Description

The present invention relates to a wallpaper pasting machine that draws in sheet-like wall covering material (hereinafter also referred to as "wallpaper") to be applied to indoor walls etc. from the rear of the pasting machine body while continuously applying glue to the backside of the material. In particular, the present invention relates to a wallpaper pasting machine that can fold up the legs while a roll of cross-cut tape is set in the machine body even with a small pasting machine body.

Currently, the application of wall coverings to interior walls in building interior construction is generally done at the interior construction site by continuously applying glue to sheet-like wall coverings using a dedicated wallpaper pasting machine. The general configuration of this wallpaper pasting machine is that the main body of the pasting machine, which is mainly composed of an upper structure and a lower structure with multiple rollers inside, is placed on a base supported by legs, and while the wallpaper sandwiched between the upper and lower structures is transported by the rollers, the glue is scooped up from the glue tank by a glue pick-up roller journaled inside the glue tank and transferred to the glue roller, which then applies the glue to the back of the wallpaper.

Wallpaper pasting machines are available in manual and automatic types. In one example of a specific configuration, a cloth unrolled from a roll is placed on the lower structure with the tip hanging down over the front of the main body, and the upper structure is closed, with the cloth sandwiched between specified rollers on the lower and upper structures. In a manual wallpaper pasting machine, the worker holds the tip of the cloth in his or her hand and pulls it forward, causing some of the rollers to rotate in response and causing other rollers to rotate in tandem via gears. In an automatic wallpaper pasting machine, the shaft of a specified roller is typically connected to a drive source such as an electric motor and rotated, causing the other rollers to rotate in tandem via gears (see, for example, Patent Document 1).

Figure 8 is an explanatory diagram showing the internal structure of a conventional automatic wallpaper pasting machine. As shown in the figure, within the upper structure 140 that constitutes the glueing machine main body 110, there are an upper pinch roller 141 that constitutes a pinch roller for taking the cloth into the glueing machine main body from the rear side, a drive roller 143 that applies tension to the cloth C to send it forward toward the front of the glueing machine main body, and a pressure roller 142 that presses the cloth C from above between the upper pinch roller 141 and the drive roller 143 and rotates to follow the movement of the cloth C. These are each supported on a shaft on the side plate of the upper structure 140 so that they are arranged parallel to each other at a predetermined interval.

Also, within the lower structure 130, which also constitutes the main body 110, the lower pinch roller 132, which forms a pair with the upper pinch roller 141 to form a pinch roller, the gluing roller 131, which applies the glue liquid in the glue tub 150 to the back of the cloth, the doctor roller 133, which comes into contact with the gluing roller 131 to adjust the amount of glue, and the leveling roller 134, which applies an appropriate tension to the cloth together with the drive roller 143 to send it forward, are supported on the side panels of the lower structure 130 so that they are arranged parallel to each other at a specified distance from each other. Also, the glue-up roller 151 is supported on both inner sides of the glue tub 150 and transfers the glue liquid in the glue tub 150 to the gluing roller 131.

Of these rollers, those arranged in the lower structure 130 are normally all linked via gears. On the other hand, those arranged in the upper structure 140 are such that the drive roller 143 is linked via gears to the gear system of the lower structure 130, and the upper pinch roller 141 and the pressure roller 142 come into contact with the cloth C being transported from rear to front by the rotational drive of the other rollers, and rotate following it due to surface friction.

In the pasting operation using a wallpaper pasting machine with such a configuration, first the upper structure 140 is opened relative to the lower structure 130, the tip of the cloth C is pulled out from the cloth roll R axially supported at the rear of the pasting machine main body 110, passed through two tension bars and a slitter 170 attached to the rear of the pasting machine main body, and then the cloth is placed on the lower pinch roller 132, pasting roller 131, and smoothing roller 134 so that the tip hangs down toward the front of the main body, and the upper structure 140 is closed to sandwich the cloth. A cloth receiving plate 180 inclined forward is installed below the front of the pasting machine main body 110, with a hook piece protruding laterally from the upper edge hung between the two legs supporting both sides of the pasting machine main body.

With the cloth C set in this way, it is driven by a drive control device (not shown) equipped with a drive motor, and the glue lifting roller 151 scoops up the glue in the glue tub via a gear and transfers the glue to the gluing roller 131. The glue transferred to the surface of the gluing roller 131 is adjusted to a specified amount by the doctor roller 133, and then transferred and applied to the back side of the cloth that is sent to the top of the gluing roller 131 via the pressure roller 142.

The glued cloth C is then pulled under tension by the drive roller 143 and the smoothing roller 134, the glued surface is smoothed by the smoothing roller 134, and the cloth C with the glued backside is sent out to the front of the main body. At this time, a core rod is placed at the center of the axis of a roll 189 of cross-cut tape, also known as "curing tape" or "underlay tape," which is necessary when performing the "overlap cutting" construction method, and the roll is attached to the bottom of the gluing machine body and laminated on one or both sides of the cloth C.

Japanese Patent Application Publication No. 5-193300

In recent years, small wallpaper pasting machines that can be mounted on small, maneuverable vehicles have become popular. On the other hand, cross-cut tape has recently become mainstream with long rolls and is becoming larger. As a result, small wallpaper pasting machines have narrow legs, and they need to be removed when folded for transportation and then reattached when used. As mentioned above, in machines that place the axis of the tape roll on a core rod, when placing the roll on the axis of the tape on the core rod that extends from the side of the wallpaper pasting machine toward the center, the tape itself needs to be clamped between a pair of side panels to prevent it from unraveling and coming off the core rod, making installation, transportation, and other handling cumbersome.

In addition, this cross-cut tape is commercially available in a variety of widths, such as 60 mm, 50 mm, 45 mm, 38 mm, 35 mm, and 25 mm, and in order to properly apply tapes of different widths, alignment is required, and as mentioned above, handling the cross-cut tape when sandwiched between a pair of side panels is cumbersome.

FIG. 2 is a side view including a cross section of a portion of the automatic wallpaper pasting machine of FIG. 1 . FIG. 2 is a side cross-sectional view of a main body of the automatic wallpaper pasting machine of FIG. 1 . 2A and 2B are perspective views of a cross-cut tape holder attached to the rear surface of the main body of the automatic wallpaper pasting machine of FIG. 1, in which FIG. 2A shows the state when the pasting position is being performed, and FIG. 2B shows the state when the legs are folded up. 5A and 5B are diagrams showing the cross-cut tape holder of FIG. 4, in which FIG. 5A is a diagram showing the tape holder, and FIG. 5B is a diagram showing the components in exploded form. 11A and 11B are explanatory diagrams of another cross-cut tape holder, where FIG. 11A is an exploded perspective view, FIG. 11B is a perspective view of one of the hanging members and a holding portion, and FIG. 11C is an exploded perspective view of FIG. FIG. 2 is an explanatory diagram showing the configuration of a cross-cut tape guide that guides a cross-cut tape in front of the automatic wallpaper gluing machine of FIG. 1, where FIG. 2A shows two components that make up the tape guide, and FIG. 2B shows the two components assembled together. FIG. 1 is an explanatory diagram showing the internal configuration of a conventional automatic wallpaper pasting machine.

In the present invention, the wallpaper pasting machine includes a pasting machine main body that moves a sheet-like wall covering from the rear of the main body along a predetermined path using multiple rollers that are driven to rotate in tandem, while continuously applying glue from a glue tub to the back side of the wall covering using a gluing roller and discharging the glue to the front of the main body, and a base section that has a pair of foldable legs that support the lower part of the pasting machine main body. The machine also includes a cross-cut tape holder that supports a roll of cross-cut tape, which is laminated by applying it along the edge of the glued wall covering, at the lower part of the pasting machine main body, and the cross-cut tape holder is slidable in the longitudinal direction of the pasting machine main body. As a result, the cross-cut tape holder can be slid to the cutting position of the slitter to apply the cross-cut tape.

In other words, by positioning the cross-cut tape holder that holds one cross-cut tape so that it can slide in the longitudinal direction of the gluing machine body, in conventional systems where the axis of the cross-cut tape roll is placed on the core rod, the tape itself needs to be clamped between a pair of side plates to prevent it from unraveling and coming off the core rod. This made handling cumbersome, but by making the cross-cut tape holder itself slidable in the longitudinal direction of the gluing machine body, the tape does not unravel, making operation easier and enabling various other innovations.

That is, the cross-cut tape holder preferably comprises an attachment plate that is placed across the short side of the gluing machine body, a rotating part that is rotatably attached to the underside of the attachment plate, and a pair of hanging members that suspend a roll of cross-cut tape attached to the underside of the rotating part, the roll having shaft parts that pivotally support the cylindrical shaft hole part of the roll from both sides, and the rotating part is capable of rotating switchably between a gluing position where the winding direction of the roll of cross-cut tape is parallel to the short side of the gluing machine body, and a folding position where the winding direction of the roll of cross-cut tape is parallel to the long side of the gluing machine body and does not come into contact with the leg folding process. This provides the advantage that the cross-cut tape can be mounted on a small vehicle with the legs folded while still set, without having to remove it.

This means that even a small wallpaper gluer that can be mounted on a maneuverable small vehicle can easily visit several interior construction sites in a day. In other words, by rotating the holder that holds the roll of cross-cut tape so that the roll of tape does not hit the legs when folding them, the cross-cut tape can be left set and the legs folded without having to be removed, allowing the machine to be mounted on a small vehicle.

The cross-cut tape holder of the wallpaper pasting machine of the present invention is provided with a mounting plate that is placed across the short side of the pasting machine body, a rotating part that is rotatably attached to the underside of the mounting plate, and a pair of hanging members that suspend a roll of cross-cut tape attached to the underside of the rotating part and have shaft parts in opposing positions that support the cylindrical shaft hole part of the roll from both sides, thereby supporting the roll of cross-cut tape on the bottom of the wallpaper pasting machine.

The cross-cut tape roll is suspended from a pair of suspension members on the underside of the rotating part, so there is a rotating part above the roll. This means that the tape will not fray due to wind, etc., and is easier to handle, compared to conventional methods in which a roll of cross-cut tape is attached to the bottom of the gluing machine body with a core rod that matches the axis of the roll.

Currently, the cylindrical core hole of commercially available cross-cut tapes is mainly 38 mm, but there are also 25 mm. It is possible to devise a way to hold two diameters of tape by attaching and detaching an adapter to accommodate these two types of tape with inner diameters. In a preferred embodiment, the cylindrical core hole of the roll of cross-cut tape is supported from both sides via an adapter with a diameter larger than the diameter of the shaft parts attached to the shaft parts provided at opposing positions of a pair of hanging members of the cross-cut tape holder.

In other words, by making the diameter of the shafts at the opposing positions of a pair of hanging members large enough to accommodate the inner diameter of the shaft core of a 25 mm tape, and the diameter of the adapter large enough to accommodate the diameter of the core of a 38 mm tape, it is possible to use tapes of two different diameters. When tapes of other diameters are released, if the diameter is 25 mm or more, it is possible to use tapes of the new diameter by using a different adapter. Also, when tapes of diameters smaller than 25 mm are released, it is possible to accommodate them by making the diameter of the shafts of the hanging members smaller and providing an adapter that can hold a 25 mm tape and an adapter that can hold a 38 mm tape.

As mentioned above, cross-cut tapes are also available in a variety of widths, such as 60 mm, 50 mm, 45 mm, 38 mm, 35 mm, and 25 mm. These various widths may be adjustable with a single touch. In other words, a preferred embodiment is one in which the distance between a pair of hanging members of the cross-cut tape holder can be changed to each of the widths.

More specifically, as shown in the examples described later, a T-shaped locking piece is formed on the rotating member side as the rotating part of the hanging member to prevent the hanging member from falling, and a rail-shaped groove is formed in the rotating member to hold this T-shaped locking piece. On both sides of the T-shaped locking piece of the hanging member, a pair of locking pieces are formed that are locked into locking grooves formed opposite both wall parts formed on both outside sides of the rail-shaped groove of the rotating member via slit grooves.

A knob piece is formed on the outside of each pair of hanging pieces of each hanging member, and by pinching the knob pieces inward, the pair of hanging pieces will be released from the hanging groove, and will be able to move along both walls of the rotating member. The hanging groove has seven slit grooves so that the width can be selected with one touch from 60 mm, 50 mm, 45 mm, 38 mm, 35 mm, and 25 mm.

In the present invention, the cloth is preferably cut to a predetermined width by a slitter and then glued, and the cross-cut tape is applied to the glued surface of the side of the glued cloth up to a length equivalent to the height of the interior wall. In a preferred embodiment, the cross-cut tape holder is made slidable in the longitudinal direction of the gluing machine body, so that the cross-cut tape can be applied in accordance with the cutting position of the slitter.

More specifically, as shown in the examples described below, the cross-cut tape is held in place by a mounting plate that is slidably mounted on the upper edges of the longitudinal shafts that face in the short direction of the base that supports the lower part of the gluing machine body, so that the cross-cut tape can be applied in accordance with the cutting position of the slitter.

In addition, in a wallpaper pasting machine of another invention, a tape guide that guides both sides of the unraveled cross-cut tape is provided on the front of the pasting machine body or base, and the tape guide has a hook piece that is hooked onto the front of the pasting machine body or base, and a sliding piece that is held slidably relative to the hook piece, and is provided with a guide piece that guides one side of the cross-cut tape formed on one side of the hook piece in the longitudinal direction of the pasting machine body, and a guide piece that guides the other side of the cross -cut tape formed in a position opposite the guide piece of the hook piece of the sliding piece, so that cross-cut tapes of various widths can be slid and reliably guided.

1. Overall configuration of an automatic wallpaper pasting machine Fig. 1 is a front view of an embodiment of the automatic wallpaper pasting machine of the present invention. Fig. 2 is a side view including a cross section of a portion of the automatic wallpaper pasting machine of Fig. 1. Fig. 3 is a side cross section of the main body of the automatic wallpaper pasting machine of Fig. 1. As shown in Figs. 1 to 3, the automatic wallpaper pasting machine of this embodiment comprises a pasting machine main body 1, a base part 15 on which the pasting machine main body 1 is placed, and legs 2 consisting of a pair of front legs 21 and rear legs 22 arranged at the lower left and right ends of the base part 15 in front and rear to support the pasting machine main body 1 at a predetermined height.

The main body 1 and the base 15 are fixed with snap locks 16 that are hooked onto two hooks on the lower side walls of the gluing machine main body 1. The base 15 and the pair of legs 2 are equipped with a folding mechanism that allows the left and right legs 2 to be folded so that they face each other, and a cover 23 is formed at the folded portion of the base 15 and the legs 2. The bottom of this cover 23 is formed with a grounding part 24 that comes into contact with the ground when folded.

The gluing machine body 1 is composed of a lower structure 3, mainly a glue tub 5, and an upper structure 4 that is placed on top of it so that it can be opened and closed. A controller 6 is attached to the lower structure 3 on one side panel 11, and a removable slitter 7 is disposed on the rear side of the lower structure 3, and the upper structure 4 is disposed so as to cover the upper part of this lower structure 3.

As the gluing roller 31 rotates due to the drive shaft of the drive source (not shown) in the controller 6, the other rollers to which the rotational motion is transmitted via gears also rotate, transporting the cloth C, one end of which has been unwound, from the roll R sandwiched between the upper and lower structures 4 and 3 from rear to front, and as it is transported over the gluing roller 31, the glue pulled up from the glue tub 5 is transferred and applied to the back of the cloth.

The gluing roller 31 is supported by pivot plates on both the left and right side walls of the lower structure 3, and is configured to be positioned as low as possible into the glue tub 5. The glue in the glue tub 5 is removed by a glue-up roller 51 that comes into contact with the gluing roller 31. The glue-up roller 51 is supported by pivots on both sides of the glue tub 5, closer to the rear than the center, and scrapes up the glue in the glue tub 5 as it rotates, transferring it to the gluing roller 31.

The gluing roller 31 is connected to the drive shaft of the controller 6, which is equipped with an electric motor that is a drive source that can be detachably attached to the gluing machine main body 1. The rotation shaft of the gluing roller 31 is linked via gears to the rotation shafts of specified rollers among the lower pinch roller 32, doctor roller 33, and leveling roller 34 arranged in the lower structure 3, and the upper pinch roller 41, pressure roller 42, and drive roller 43 used as length inspection rollers arranged in the upper structure 4.

As shown in FIG. 3, the smoothing roller 34 has multiple claws attached to it at approximately equal intervals in the longitudinal direction by spacer members to guide the glued cloth C sent through the smoothing roller 34 to the front of the gluing machine body 1.

In addition, on both sides of the wallpaper pasting machine, there is a lever that drives an eccentric gear that is eccentrically fixed to the rotating shaft of the doctor roller 33. This lever moves the shaft end of the doctor roller 33 held by the eccentric gear relative to the pasting roller 31, changing the relative distance between the doctor roller 33 and the pasting roller 31, making it possible to adjust the amount of paste that adheres to the pasting roller 31.

A cloth support bracket 25 is rotatably arranged on the pair of left and right legs 2, and a cloth core rod 26 that passes through the center of the original roll R is supported at the tip of the cloth support bracket 25.

The wall covering material (cloth) C unwound from the original roll R is conveyed to the slitter 7 while being bent by a first tension bar 61 installed below the slitter 7 and a second tension bar 62 installed on the rear leg 22, and both sides of the cloth C are cut off. The cloth, the back side of which has been applied with glue by the gluing roll of the gluing machine main body 1, has the tape unwound from the cross-cut tape roll located below the gluing machine main body 1, and is attached to the back side of the side of the cloth C via the cross-cut tape holder 80 installed in front of the gluing machine main body 1, and is discharged from the front onto a cloth receiving plate (not shown).

As shown in Figure 3, the second tension bar 62 of the leg is attached by forming leg tension bar holders 27 at opposing positions on the rear leg 22, each of which has a U-shaped groove formed diagonally downward toward the rear and a guide ridge protruding from its center, and fitting the guide grooves (not shown) formed on both ends of the second tension bar 62 into the guide ridges. This second tension bar 62 makes it possible to apply good tension.

The slitter 7 is mounted in an attachment opening in the upper rear wall surface of the lower frame of the lower structure 3 of the gluing machine main body 1. The slitter 7 has a guide surface portion 72 arranged in the center of the rear back surface, and at both ends of the guide surface portion 72, a cutter box set 71, which has a single rotating blade that rotates at high speed and a motor that drives it inside, is arranged so that it can slide in the directions of both ends.

On the guide surface 72 side of the slitter 7, a tension bar support 73 is provided on the side wall of the slitter, which supports a tension bar 74 that presses the cloth transported on the guide surface 72 against the guide surface 72. The tension bar support 73 has the tension bar 74 attached to one end, and the other end is provided with a fulcrum (not shown) that allows the tension bar to swing between a pressing position and a release position.

2. Cross-cut tape holder 1
Fig. 4 is a perspective view of the cross-cut tape holder attached to the back of the main body of the automatic wallpaper pasting machine of Fig. 1, Fig. 4a shows the state when pasting, and Fig. 4b shows the state when the legs are folded. Fig. 5 is a structural diagram of the cross-cut tape holder of Fig. 4. On the underside of the pasting machine main body 1, cross-cut tape holders 80 for holding a roll 89 of cross-cut tape are provided on both sides in the longitudinal direction of the pasting machine main body 1.

More specifically, the cross-cut tape holder 80 comprises a mounting plate 81 slidably mounted on the upper edges of the longitudinal axes opposed in the short direction of the base 15 that supports the lower part of the gluing machine main body 1, a rotating member 82 as a rotating part attached to the underside of the mounting plate 81 so as to be rotatable at least 90 degrees, and a pair of hanging members 83 that support the cylindrical shaft hole of a roll 89 of cross-cut tape attached to the underside of the rotating member 82 from both sides and hang the roll 89.

The cylindrical core hole of the cross-cut tape roll 89 is mainly 38 mm in inner diameter, but some have an inner diameter of 25 mm. The adapter 84 can be attached and detached to hold tapes of two diameters to fit the tapes in these two core holes. That is, the hanging member 83 is formed with a cylindrical holding portion 85 that supports the 25 mm core hole from both sides and holds and suspends the roll 89, and an adapter 84 that can be inserted and held in the 38 mm core hole is inserted into the holding portion 85 to accommodate this.

The distance between the pair of hanging members 83 and the rotating member 82 is changeable. More specifically, a T-shaped locking piece 86 is formed on the rotating member 82 side of the hanging member 83 to prevent the hanging member 83 from falling, and a rail-shaped groove is formed in the rotating member 82 to hold the T-shaped locking piece 86. On both sides of the T-shaped locking piece 86 of the hanging member 83, a pair of locking pieces are formed that are locked into locking grooves 87 formed opposite both wall portions formed on both outer sides of the rail-shaped groove of the rotating member 82 via slit grooves.

A knob piece 88 is formed on the outside of the pair of hook pieces of each hanging member 83, and by pinching the knob pieces 88 inward, the pair of hook pieces are released from the hook groove 87, and can move along both walls of the rotating member 82. The hook groove 87 has seven slit grooves so that the width can be selected with one touch from 60 mm, 50 mm, 45 mm, 38 mm, 35 mm, and 25 mm.

3. Cross-cut tape holder 2
6 is an explanatory diagram of another cross-cut tape holder, in which FIG. 6 is an exploded perspective view, FIG. 6 is a perspective view of one of the hanging members and the holding portion, and FIG. 6 is an exploded perspective view of FIG. 6. The cross-cut tape holder 90 of this embodiment, like the cross-cut tape holder 80 shown in FIG. 4, comprises a mounting plate 91 slidably hung on the upper edge portions of the opposing longitudinal shafts facing in the short direction of the base portion 15 supporting the lower portion of the gluing machine main body 1, a rotating member 92 as a rotating portion attached to the underside of the mounting plate 91 so as to be rotatable at least 90 degrees, and a pair of hanging members 93 that support the cylindrical axial hole portion of the roll of cross-cut tape attached to the underside of the rotating member 92 from both sides to hang the roll.

The mounting plate 91 and the rotating member 92 are configured such that the rotating member 92 is attached to the inside of a pair of peripheral members 91a along a portion of the outer periphery of the rotating member 92 at an opposing position, and four screws are screwed into the pair of peripheral members 91a, so that the edges of the screw heads prevent the rotating member 92 from falling off the mounting plate 91.

The distance between the pair of hanging members 93 and the rotating member 92 is changeable. More specifically, a T-shaped locking piece 96 is formed on the rotating member 92 side of the hanging member 93 to prevent the hanging member 93 from falling, and a rail-shaped groove is formed in the rotating member 92 to hold the T-shaped locking piece 96. On both sides of the T-shaped locking piece 96 of the hanging member 93, a pair of locking pieces are formed that are locked into locking grooves 97 formed opposite both wall portions formed on both outer sides of the rail-shaped groove of the rotating member 92 via slit grooves.

As with the cross-cut tape holder 80, a pair of hook pieces of each hanging member 93 has a tab 98 formed on the outside thereof, and by pinching the tabs 98 together inward, the pair of hook pieces are released from the hook groove 97, allowing them to move along both walls of the rotating member 92. The hook groove 97 has seven slit grooves formed so that widths of 60 mm, 50 mm, 45 mm, 38 mm, 35 mm, and 25 mm can be selected with a single touch.

The cross-cut tape holder 90 of this embodiment also has a holding portion 95 on each of the pair of hanging members 93 so that it can hold tapes with two types of shaft hole portions, an inner diameter of 38 mm and an inner diameter of 25 mm. The holding portion 95 consists of a small adapter 94a that is attached to the shaft hole portion with an inner diameter of 25 mm, and a large adapter 94b that is attached to the shaft hole portion with an inner diameter of 38 mm. The shaft portion of the large adapter 94b is attached to the tubular shaft portion of the small adapter 94a and integrated to form the holding portion 95. The tip portions of the shaft portions of the small adapter 94a and the large adapter 94b are tapered from the tip toward the enlarged diameter portion as a hook portion, and four rows of slits are formed evenly from the tip of the shaft portion toward each adapter portion.

To integrate the small adapter 94a and the large adapter 94b, the axial core of the large adapter 94b is attached inside the tubular axial core of the small adapter 94a. At this time, the hook portion at the tip of the axial core of the large adapter 94b is inserted into the axial core of the small adapter 94a while shrinking in diameter, and the tip reaches the inside of the adapter part of the large adapter 94b, the hook portion expands, the small adapter 94a and the large adapter 94b are integrated, and the holding part 95 is formed.

The relationship between the hanging member 93 and the holding portion 95 will now be described. The through hole 93a of the hanging member 93 is connected to a separation enlarged diameter through hole 93b above it. A border is formed around the periphery of the roughly semicircular through hole 93a, and its thickness matches the length of the axial core between the adapter portion and the hook portion of the small adapter 94a. Therefore, at the position of this through hole 93a, the hook portion at the tip of the axial core of the small adapter 94a cannot be removed.

On the other hand, the edge of the roughly semicircular separation-use expanded diameter through hole 93b has a taper formed on both the front and back that narrows toward the center. This taper allows the hook portion at the tip of the shaft of the small adapter 94a to narrow when entering or exiting the separation-use expanded diameter through hole 93b, allowing it to be attached or removed.

Between the through hole 93a and the separation enlarged diameter through hole 93b, there is a movable piece 93c that can move outward from each through hole, and the small adapter 94a attached to the separation enlarged diameter through hole 93b can be moved to the through hole 93a, or the small adapter 94a at the through hole 93a position can be moved to the separation enlarged diameter through hole 93b and locked in that position. The large adapter 94b can be attached to the small adapter 94a at either the through hole 93a or the separation enlarged diameter through hole 93b position.

4. Tape guide Figure 7 is an explanatory diagram showing the configuration of a cloth tape tape guide that guides a cloth tape to the front of the automatic wallpaper pasting machine in Figure 1, where Figure 7a shows two components that make up the tape guide, and Figure 7b shows the two components combined. As shown in the figure, the cloth tape tape guide 100 comprises a hook piece portion 101 that is hooked onto the front of the pasting machine main body 1, and a slide piece portion 106 that is held slidably relative to this hook piece portion 101.

The hook piece 101 has a roughly rectangular outer shape, and is provided with a hook portion 102 on its upper edge that hooks onto the upper edge of the glue tub 5 of the gluing machine main body 1, and a guide portion 103 on one side perpendicular to the upper edge that contacts one side of the cloth tape. An H-shaped cutout 105 is formed in the center of the roughly rectangular plate portion 104 on which the hook portion 102 and guide portion 103 are formed, and the upper and lower sides of the cutout 105 are recessed from the surface of the plate portion 104.

The slide piece 107 of the slide piece 106 enters the H-shaped cutout 105, and the guide portion 108 of the slide piece 106 on the opposite side can hold the cross tape at any width together with the guide portion 103 of the hook piece 101.
