On the downstream side of the portion of the first conveying path 21 inclined in the width-shifting direction, the sheet 3a is placed in parallel with the second conveying path 22 by another conveying belt provided in parallel with the second conveying direction. It is a conveyance path for conveyance.

  The other (GS side) second transport path 22 of the bonding transport apparatus 20 is composed of transport belts 24, 24, and a feed roller 25 is in rolling contact therewith. And the conveyance surface of this is the same plane as the said 1st conveyance path 21 from the start end to the termination | terminus, and is the same length. A flip-up machine 27 that changes the height of the inner edge of the sheet 3b is provided in the middle portion of the second transport path 22. Further, on the downstream side of the flip-up machine 27, a first jump-up part holding machine 28 for holding the jump-up part of the inner end part jumped up by the flip-up machine 27, and the subsequent jump to the downstream part. A second flip-up holding machine 28a for holding the raising part and a glue margin part spreading machine 29 for spreading the glue margin part of the sheet 3b that has been flipped up and held inward in the width direction of the sheet 3b are provided. It has been.

Said flip-up machine 27, the inner end portion of the sheet 3b that is conveyed by the second conveying path 22, a spatula member 30 flipping up onto the side following the transfer operation of this, splashing at the spatula member 30 It consists of a pressing member 31 that presses the upper surface outside the part to be raised. The upstream side of the pressing member 31 is warped upward.

  The first and second flip-up unit holders 28 and 28a are composed of two guides 32a and 32b that guide both sides of the flipped-up pieces in the transport direction.

  The glue margin portion spreader 29 is moved obliquely downward from the outside to the inside at a position lower than the second flip-up portion holder 28a. In this state, the glue margin portion which is the inner end portion of the second sheet 3b is spread with the roller 33 in a state of moving inward. A plurality of the rollers 33 are provided at intervals on the shaft 34. The roller 33 may be elongated in the axial direction.

  The pressing member 31 of the jumping mechanism 27, the first and second flip-up part holding machines 28 and 28a, and the adhesive margin pressure spreader 29 are supported above the second transport part 22 by a support mechanism (not shown). Yes. The first and second flip-up unit holders 28 and 28a may be integrated in the length direction.

  The operation of this embodiment will be described below.

  The first and second sheets 3a and 3b are fed one by one from the paper feeder 1 toward the laminating and conveying apparatus 20 at the same time. At this time, the first stopper 4 moves in and out, and the sheets 3a and 3b are fed in parallel after the leading ends are aligned.

  The first sheet 3a on the near side is in the first conveyance path 21 of the bonding conveyance apparatus 20, and the second sheet 3b on the back side is the second conveyance path 22 in the conveyance apparatus 20. Then, the sheet is conveyed until the tip abuts against the second stopper 15 provided at the end portion of the bonding and conveying apparatus 20.

At this time, the first sheet 3a transported through the first transport path 21 is shifted inward to a position where it abuts on the guide plate 23 according to this transport operation. At this time, the inner edge of the sheet 3a is prevented from entering the lower side of the eaves provided at the tip of the guide plate 23 and turning up. The first sheet 3a is guided by the guide plate 23 and conveyed downstream in parallel with the second conveyance path 21 .

The paste 16a is applied to the filament.

On the other hand, while the second sheet 3 b conveyed through the second conveyance path 22 is conveyed along the second conveyance path 22, the inner edge of the second sheet 3 b faces the spatula member 30 of the flip-up machine 27. Then it is transported while being lifted up. At this time, since the upper surface on the outer side of this portion is pressed by the pressing member 31, the inner edge is flipped up by the spatula member 30.

  Then, the second sheet 3b in this state is conveyed to the midstream portion of the laminating and conveying apparatus 20, so that the above-mentioned bounce-up portion enters the guides 32a and 32b of the first bounce-up portion holder 28. It is guided and transported while maintaining this state of jumping. Further, even during the conveyance to the downstream portion, the bounce-up portion is kept in the bounce-up state by the second bounce-up portion holding machine 28a, and hits the second stopper 15 in this state and is stopped.

  At this time, since the first and second transport paths 21 and 22 are transported synchronously, the first and second sheets 3a and 3b transported on both transport paths 21 and 22 are At the same time, they abut against the second stopper 15 and are positioned. Then, the paste margin pressure spreader 29 is operated in such a state that the both sheets 3a and 3b are positioned and the leading ends are aligned, and from the position shown in FIG. 4A to the position shown in FIG. That is, the lower side of the second flip-up part holding machine 28a is moved obliquely from the upper side to a position where the glue margin part, which is the inner end of the second sheet 3b, is pressed. The inner edge of the sheet 3b in a state of being flipped up by the holding machine 28a is developed inward, and this portion is spread by the roller 33 to the glue margin portion of the first sheet 3a. The pressure applied by the roller 33 at this time is in a temporarily attached state, and this glue is absorbed while the second stopper 15 is immersed and the both sheets 3a and 3b are conveyed from the laminating and conveying apparatus 20 to the intermediate conveying path 17. The surrogate is pressed and bonded by the press roller device 18.

As described above, in this embodiment , one of the first and second sheets 3a fed from the paper feeder 1 is transported through one transport path 21 of the bonding transport device 2. In the meantime, the width is shifted toward the other conveyance path 22. Then, while the inner edge (adhesive margin) of the second sheet 3b transported on the second transport path 22 is transported on the other transport path 22, it is flipped up by the flip-up machine 27. Thus, this portion is vertically separated from the inner end of one sheet 3a, and the inner ends of both sheets 3a and 3b are opposed to each other in an overlapping manner.

  In these embodiments, the overlap of the inner end portions (adhesive allowances) of the first and second sheets 3a and 3b and the overlapping action to the overlapping possible state is as follows. This is performed while the transport devices 2 and 20 are transported, that is, according to the transport operation of the sheets 3a and 3b transported through the transport paths 5, 6, 21, and 22.

In the above-described embodiment, the flip-up machine 27 that flips up the inner end of the second sheet 3b, the spatula member 30 that jumps up the inner end of the sheet 3b as shown in FIG.

In addition, the spatula member 30 'is curved so that the front end thereof is lower than the conveying surface of the sheet 3b. Further, the tip of the guide 32'b located on the outside is bent downward so that the lower surface is positioned slightly higher than the conveying surface to form a pressing member 31 '. The two members 30 'and 31' constitute a flip-up machine 27 '.

  According to this configuration, the second sheet 3b conveyed through the second conveyance path 22 is flipped up by the spatula member 30 'of the flip-up machine 27'. At this time, the outer side of this portion is pressed by the pressing member 31 ′, and the inner end portion of the sheet 3 b is flipped up, and the first flip-up unit holding machine 28 ′ keeps the flip-up state. It is conveyed in the state.

  At this time, as shown in FIG. 6, the height of the guide 32'a on the inner side of the flip-up portion holding machine 28 'is made higher than that of the outer guide 32'b to increase the step difference. The flip-up posture of the flip-up end can be brought close to an upright state.

  In this embodiment, the guides 32b and 32'b on the outer side of the upstream flip-up unit holders 28 and 28 'are set so as to approach the upper surface of the conveyed sheet 3b. You may make it guide the upper surface of the sheet 3b conveyed by 32b and 32'b.
