  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows a continuous labelless body 10 of the present embodiment. The label-less continuous substrate 10 is a type in which a mount (release paper) is not provided on the exposed surface of the adhesive applied to one side of the substrate 20.

  The boardless label continuous body 10 is formed by continuously forming a plurality of boardless labels 11 in a strip shape, and each boardless label 11 can be separated from the label perforation 12. In the same figure, the strip-like non-backing label continuous body 10 is shown in a roll-up state, and the base-less label continuous body 10 is distributed in the market in such a state that it has been wound up in a roll-like manner. Is used by setting a roll-like uncontinuous label continuous body 10 in a printer (not shown). Moreover, the branch continuous label 10 of this embodiment does not use a branch pipe that becomes a winding core when winding the label continuous body 10.

  As shown in FIG. 2, the label-less continuous body 10 includes a base material 20, a release agent layer 21 provided on the front surface (lower surface in the figure) 20 a of the base material 20, and the rear surface (upper surface in the figure). ) The pressure-sensitive adhesive layer 22 provided on 20b and at least a three-layer structure.

  As the base material 20, for example, a paper base material made of high-quality paper, coated paper, or art paper, or a synthetic material made of PET (polyethylene terephthalate), PE (polyethylene), PP (polypropylene), or PS (polystyrene). A resin film can be used. In addition to these materials, it may be a sheet combining a plurality of types of the above-mentioned synthetic resins, a composite sheet combining a synthetic resin film and a paper base material, and a thermal print capable of thermal printing. It may be paper.

  As the release agent layer 21, for example, an ultraviolet curable silicone, a thermosetting silicone, a solvent type silicone, an alkyl pendant polymer, a fluorine-based release agent, or the like can be used.

  Examples of the pressure-sensitive adhesive layer 22 include pressure-sensitive adhesives such as emulsion systems (in which the pressure-sensitive adhesive is dispersed in water), solvent systems (in which the pressure-sensitive adhesive is dissolved in a solvent), and hot melt systems (using thermoplasticity). Can be used. Examples of the material include pressure sensitive adhesives such as synthetic rubber type, natural rubber type, acrylic resin type, polyvinyl ether resin type, urethane resin type, and silicone resin type. The adhesive strength of the adhesive is arbitrarily set according to the application.

  By the way, when manufacturing the label continuous body 10 without the mount, first, the wide label continuous body is cut into a desired width while pulling out the winding end portion of the roll in which the roll is thickly wound. A small length is wound around a winding shaft of a small winding machine (not shown). By this small roll, the roll-like baseless label continuous body 10 shown in FIG. 1 is formed. Then, as shown in FIG. 3A, in the state where the continuous label body 10 without backing paper is pulled out from the thick winding roll and divided into small portions, the leading end portion that is pulled out becomes the winding side end portion 10a when performing the small winding. 3A to 3C, the pressure-sensitive adhesive layer 22 is the upper surface and the release agent layer 21 is the lower surface, and the thickness is omitted for convenience.

  Here, as shown in FIG. 3B, the winding-side end portion 10a of the non-mounting label continuous body 10 has a turn-back length L (see FIG. 3C), for example, at least within the wound-up end. A turn-back portion 13 is provided that turns back so as to be longer than the length l of the circumference 10b (see FIG. 3D) (L ≧ l). And when the winding side edge part 10a is folded back from the folding | returning part 13, the adhesive layer 22 of the winding side edge part 10a and the adhesive layer 22 which overlaps and overlaps are mutually bonded together. That is, by sticking the adhesive layers 22 together, the outer surface of the winding side end portion 10a is brought into a non-adhesive state.

  In the present embodiment, the folded portion 13 is formed by a perforation 13m extending in the width direction of the non-mounting label continuous body 10. The folded portion 13 is not limited to the perforation 13m, and may be any structure that facilitates folding, such as a V-shaped groove or a thin portion. For example, a crease line formed by pressing predetermined teeth or a half cut line formed by cutting to a predetermined depth in the thickness direction of the label with a cutting blade may be used.

  In this way, the adhesive layer 22 is bonded together by folding the winding-side end portion 10a from the folded portion 13 in the direction of the arrow α in FIG. At this time, the upper surface of the wound-up winding side end portion 10a is a release agent layer 21, and this release agent layer 21 is the innermost circumference of the continuous labelless body 10 without a mount.

  And as shown in FIG.3 (d), the label continuous body 10 without board | substrate is made into the same direction (arrow (beta) direction in FIG.3 (d), (e)) as a whole by making the folding | turning part 13 the winding front-end | tip 10c. By winding up and winding up to a desired length, the roll-less baseless label continuous body 10 shown in FIG. 1 is completed.

  Next, the continuous labelless body 10 and its winding method will be described. 3 (a) to 3 (e) show a series of steps for winding the continuous paperless label continuous body 10 subdivided from the thick roll onto the winding shaft of the small winding machine, and FIG. 3 (a) shows the subdivided baseboard. The state where the continuous label body 10 is drawn out in a band shape is shown.

  FIG. 3 (b) shows the folded portion forming step, and the position where the folded length L is longer than at least the wound inner peripheral length l at the winding side end portion 10a of the mountless label continuous body 10. The folded portion 13 is provided. Then, it transfers to the folding | turning process of FIG.3 (c), the winding side edge part 10a is folded back from the folding | turning part 13, and adhesive layer 22 is bonded together (refer FIG. 4). Thereafter, the process proceeds to the winding process shown in FIGS.

  In the winding process, first, as shown in FIG. 3D and FIG. 5, the wound winding side end portion 10 a is wound inward on the winding shaft of the small winding machine in the β direction. At this time, the folded-back portion 13 becomes the winding tip 10c. Next, as shown in FIGS. 3 (e) and 6, with the winding side end 10a wound around the winding shaft, the baseless label continuous body 10 is wound up in the same direction β as a whole. . Then, when the continuous labelless continuous body 10 is wound up by a predetermined length (11 desired labels without the baseboard), the continuous labelless continuous body 10 is cut (not shown). In addition, the cross-sectional views of FIGS. 4 to 6 show the enlarged thickness of the continuous labelless body 10 for easy understanding.

  According to the continuous labelless body 10 of the present embodiment, when the continuous labelless body 10 is pulled out from the large roll and rolled, the winding side end portion 10a is folded back from the folding portion 13 so that the winding side The pressure-sensitive adhesive layer 22 at the end 10a and the pressure-sensitive adhesive layer 22 in the general part of the non-mounting label continuous body 10 are bonded together. In this way, the folded-back end portion 10a is folded back to the pressure-sensitive adhesive layer 22 side, whereby the folded-back portion 13 becomes the leading end. After the folded-back portion 13 is formed as the rolled-up leading end 10c, The direction can be wound in the same direction β as the rotational direction β of the winding shaft of the small winding machine.

  At this time, the release agent layer 21 of the folded-up winding side end portion 10a is exposed on the inner periphery 10b of the non-mounting label continuous body 10 by setting the return length L to be longer than the inner peripheral length l. Since the non-adhesive state can be achieved, it is possible to prevent sticking of the innermost circumference of the continuous labelless continuous body 10 that does not use a branch pipe. Further, since the label continuous body 10 without the mount can be wound around the winding shaft in the same direction β from the beginning to the end of winding, the winding operation can be simplified and the structure of the small winding machine can be simplified. . Furthermore, since the innermost stickiness prevention is performed at the winding side end portion 10a which is a part of the non-mounting label continuous body 10, it is possible to prevent the number of parts from increasing.

  Moreover, according to this embodiment, the folding | returning part 13 is the perforation 13m extended in the width direction of the label continuous body 10 without mount. For this reason, when the separation part of the continuous label 11 without the mount is formed by the label perforation 12, when the label perforation 12 for separation is formed by a label processing machine or a perforation forming device, The perforation 13m of the folded portion 13 can be easily formed by a series of processes for forming the label perforation 12.

  The perforations 13m are formed with a pitch in units of the length of the label 11 having no mount, but the folded portion 13 can be formed using the label perforations 12. In this case, the label perforation 12 that is used as the turn-back portion 13 is the label perforation 12 that is the closest to the length of the inner circumference of the continuous labelless body 10 from the front end of the continuous labelless body 10 without the mount.

  Furthermore, according to the present embodiment, when winding the continuous label-less continuous body 10, the folded-back portion forming step is provided with the folded-back portion 13 at the winding-side end 10 a of the continuous paper-less label continuous body 10, and the next folding step. Then, the winding-side end portion 10a is folded and the pressure-sensitive adhesive layers 22 are bonded to each other, and in the next winding process, the non-mounting label continuous body 10 is entirely wound in the same direction with the folding portion 13 as the winding tip 10c. It is supposed to take. Therefore, the series of processes can efficiently manufacture the continuous labelless continuous body 10 that eliminates the stickiness of the innermost circumference while simplifying the process of winding the continuous labelless continuous body 10 while preventing the number of parts from increasing. .

  In the present embodiment, the case where the label perforation 12 is provided in advance as the separation portion of each mountless label 11 has been described. However, the cutting device provided in the printer without forming the label perforation 12 in this way. For example, the non-mounting label continuous body 10 may be separated for each non-mounting label 11.

  FIG. 7 shows another embodiment, and the same components as those in the above embodiment are denoted by the same reference numerals and redundant description is omitted.

  In the present embodiment, as shown in FIG. 7 (d), a refolding portion 14 is provided by further folding the folded tip portion 10d to the folded tip portion 10d of the winding side end portion 10a folded from the folded portion 13. It has become.

  The refolding part 14 of this embodiment is formed through the process shown to Fig.7 (a)-(d). FIG. 7A corresponds to FIG. 3A, and shows a state before the winding side end portion 10 a is folded back from the folding portion 13. Note that FIG. 7 is shown opposite to that in FIG.

  In forming the refolding portion 14, first, as shown in FIG. 7A, the folding portion 13 is separated from the winding-side end portion 10 a by a certain distance D with the folding portion 13 as a boundary (symmetric axis). A pair of first fold lines 15a and 15b are provided in parallel. The fixed distance D corresponds to the folding allowance of the refolding portion 14 as will be described in detail with reference to FIGS. Of course, the folded portion 13 is perpendicular to the longitudinal direction of the labelless continuous body 10 without mount.

  Then, the pair of first fold lines 15a and 15b are directed to the other side 10E2 with a predetermined angle θ in a direction away from the folded portion 13 from the points P1 and P2 where the pair of first fold lines 15a and 15b intersect with the one side 10E1. A pair of second fold lines 16a and 16b are provided. In this embodiment, θ is set to 45 degrees, but is not necessarily limited to 45 degrees.

  The first fold lines 15a and 15b and the second fold lines 16a and 16b are formed by crease lines or half-cut lines. The crease line is formed by pressing predetermined teeth. The half-cut line is formed by cutting to a predetermined depth in the thickness direction of the label with a cutting blade. Note that the first fold lines 15a and 15b and the second fold lines 16a and 16b may be perforated if there is no restriction in terms of design when printing with a printer. Still further, the first fold lines 15a and 15b and the second fold lines 16a and 16b can be selectively used as crease lines, half cut lines, perforations, and the like depending on the location.

  Next, as shown in FIG. 7 (b), the winding-side end portion 10 a is folded back from the folding portion 13. This state corresponds to FIG. At this time, the first fold lines 15a and 15b provided as a pair with the folding portion 13 as the axis of symmetry overlap with each other, and the second fold lines 16a and 16b provided as a pair also overlap with each other.

  FIGS. 7C and 7D show a substantial formation process of the refolding portion 14. First, as shown in FIG. 7C, the second folding lines 16 a and 16 b are viewed in the valley folding direction (FIG. 7 (b) γ direction). In this state, the leading end 10d of the folded leading end 10d protrudes from one side 10E1 of the continuous label body 10 without mount (corresponding to the distance D). At this time, the first folding lines 15a and 15b are connected to the one side 10E1. Match. Next, as shown in FIG. 7 (d), the leading end portion 10e is folded back in the valley folding direction (δ direction in FIG. 7 (c)) from the first fold lines 15a and 15b, so that the leading end portion 10e is a non-mounting label continuous body. It is folded back within a width of 10 to complete the refolding portion 14.

  Therefore, according to the present embodiment, since the refolding portion 14 is provided at the folding front end portion 10d of the winding side end portion 10a, the refolding portion 14 serves as a reinforcing portion, as shown in FIG. It is possible to maintain the strength of the inner periphery 10b of the continuous paperless label continuous body 10 wound up. For example, if D is made small, L ′ can be secured larger than the innermost circumference, but the strength is reduced. On the other hand, if it is large, the strength is increased, but L ′ is shortened. Therefore, it is desirable to form the maximum D while securing L ′.

  Further, the refolding portion 14 is folded twice from the first fold lines 15a and 15b and the second fold lines 16a and 16b, thereby being doubled by the leading end portion 10e folded back within the width of the label 10 without mount. Since the folded portion can be provided, the reinforcing effect on the inner peripheral surface 10b can be further enhanced.

  Needless to say, even in the present embodiment, when the continuous paperless label continuous body 10 is wound, the refolding portion 14 is wound as a whole in the same direction. At this time, the length of the L ′ portion in FIG. 7D is at least the length of the inner periphery 10 b of the non-mounting label continuous body 10.
