Usually, the continuous adhesive paper 1 is, for example, shown in FIGS.
As shown in, by forming a plurality of separation perforations 2 at predetermined intervals in the longitudinal direction of the belt-shaped form,
In many cases, the adhesive paper for each unit partitioned by the separation perforations 2 is used as various forms, and the adhesive paper for each unit is generally referred to by the name of a label paper, a sticker, or the like. It is used as a sticking paper for various purposes. Further, as a configuration of the continuous adhesive paper 1, the adhesive layer 5 of the continuous paper 3 having the adhesive layer 5 on the back surface is used.
A continuous release paper 4 is releasably attached on the surface of the sheet, and a predetermined copy of continuous paper is superimposed on the continuous paper 3 according to the purpose of use, thereby forming a copyable slip set. In some cases. When the continuous paper 3 is attached to an article or the like, the continuous release paper 4 is separated from the adhesive layer 5 on the back surface of the continuous adhesive paper 1 as shown in FIG. It is something to attach.

Next, a case where continuous adhesive paper is produced by the method for producing continuous adhesive paper of the present invention will be described with reference to FIGS. First, as shown in FIG. 4, the continuous release paper 4 in the form of a roll is transported in the longitudinal direction by the transport roller 6, and the continuous release paper 4 is cut by a rotary blade provided with a slit blade 7, which is a cutting step. Is formed. Slit 1 formed by cutting into continuous release paper 4
3 is preferably formed linearly at regular intervals with respect to the longitudinal direction of the continuous release paper 4 and at right angles to the longitudinal direction of the continuous release paper 4. When the sheet is transported in the longitudinal direction, an excessive force is applied to a part of the continuous release paper 4 to reduce the risk of an accident such as the continuous release paper 4 being cut during the transport.

On the other hand, while the rolled continuous paper 3 is transported in the longitudinal direction by the transport roller 6, an adhesive is applied to the back surface of the continuous paper 3 by the adhesive coating device 8 provided with the adhesive coating roller 8a. The pressure-sensitive adhesive layer 5 is formed. afterwards,
While superposing the continuous release paper 4 on the lower side of the continuous paper 3 provided with the adhesive layer 5 on the back surface, the continuous paper 3 and the continuous release paper 4 are separated by using at least one pair of pressure bonding rollers 9 in a bonding process. The continuous release paper 4 is stuck on the pressure-sensitive adhesive layer 5 while being sandwiched between the pressure rollers 9 so as to be peelable.

Next, the continuous paper 3 and the continuous release paper 4 bonded together are formed with a perforated perforation 2 at a predetermined interval in the longitudinal direction by a rotary blade provided with a horizontal perforation blade 10 thereafter. It is folded in a zigzag state based on the perforation 2 for cutting. In this case, a roll state may be used instead of the zigzag state. In the vicinity of both sides of the continuous paper 3 and the continuous release paper 4 in the longitudinal direction, marginal punch holes 11 are formed at regular intervals in advance for feeding paper by hooking the pins of a pin tractor when transporting each paper. Keep it.

Incidentally, in the cutting step, the slit 13 may be formed by cutting the continuous release paper 4 by another method without necessarily using the slit blade 7 by the rotary blade. Also, in the laminating step of laminating the continuous release paper 4 on the lower side of the continuous paper 3 provided with the pressure-sensitive adhesive layer 5 on the back surface, the present invention is not limited to the pair of pressure rollers 9 and may be applied by another method. You may make it match.

In the cutting step for forming the slit 13 in the continuous release paper 4, there is a method of forming slits of various shapes as shown in FIGS. 5 and 6, for example. FIGS. 5 and 6 show an adhesive provided on the back surface of the continuous paper 3 with the back side of the continuous paper 3 facing upward so that the slit 13 formed in the continuous release paper 4 can be easily understood. FIG. 3 is a perspective view of a case where continuous release paper 4 is overlapped from above the agent layer 5. FIG. 5 shows the types of slits when marginal punch holes 11 are formed near both sides in the longitudinal direction of the continuous paper 3 and the continuous release paper 4, and FIG. The types of the slits 13 when marginal punch holes 11 are formed near both sides in the longitudinal direction and the marginal punch holes 11 are formed only near one side of the continuous release paper 4 are shown.

The continuous release paper 4 shown in FIG. 5A is provided with a portion 12 where no slit is formed near one end in the width direction of the continuous release paper 4 in the cutting step.
A linear slit 13 is formed in the remaining portion in the other width direction up to the other end. FIG. 5 (b)
In the continuous release paper 4 shown in FIG. 5, in the cutting step, a portion 12 where no slit is formed is provided near both ends in the width direction of the continuous release paper, and a linear slit 13 is provided in the remaining portion in the other width direction. To form. Then, in the continuous release paper 4 shown in FIG. 5C, in the cutting step, portions 12 where no slits are formed near both ends and near the center are provided in the width direction of the continuous release paper 4, and other widths are provided. A linear slit 13 is formed in the remaining portion in the direction.

Next, the continuous release paper 4 shown in FIG.
Is a portion 12 where no slit is formed near one end in the width direction of the continuous release paper 4 in the cutting step.
And a linear slit 13 is formed in the remaining portion in the other width direction up to the other end. Further, in the continuous release paper 4 shown in FIG. 6 (b), in the cutting step, portions 12 where no slits are formed near both ends in the width direction of the continuous release paper are provided, and the remaining portions in the other width direction are provided. A linear slit 13 is formed on the substrate. Although not shown, as in FIG. 5 (c), in the cutting step, portions where no slit is formed are provided near both ends and near the center in the width direction of the continuous release paper, and the remaining portions in the other width directions are provided. You may make it form a linear slit in a part.

Further, the slit 13 is formed at a position where the continuous adhesive paper 4 is stuck on the adhesive layer 5 of the continuous paper 3 after the cutting step, and then the slit 13 is formed in the longitudinal direction by a rotary blade provided with a horizontal sewing blade 10. It is preferable to form the cut perforations 2 at predetermined intervals at positions overlapping the positions where the cut perforations 2 are formed. Therefore, in the continuous adhesive paper 1 manufactured by the method of the present invention, the slit 13 is formed at a position overlapping the cutout perforation 2 as shown in FIGS. By doing so, the appearance is similar to continuous adhesive paper on which a general perforation 2 is formed, and there is no sense of incongruity. Further, when it is separated from the perforation 2 and used as an adhesive paper for each unit. This is particularly effective because when the release paper is peeled off from the pressure-sensitive adhesive layer 5, it is not accidentally cut off from the slit portion.
The slit 13 does not necessarily have to be formed at a position overlapping the perforation 2 for cutting.

As described above, the present invention relates to a method for producing a continuous adhesive paper in which a continuous release paper is adhered on an adhesive layer of a continuous paper having an adhesive layer on the back surface. Continuous adhesive paper can be manufactured without any gaps and wrinkles between the adhesive layer and the continuous release paper, thus preventing defective products. can do.

In particular, the slit is formed at a position overlapping with a cut perforation formed in the continuous adhesive paper, so that the slit paper is separated from the cut perforation to form an adhesive paper for each unit, and then the release paper is peeled off. It is possible to peel off from the slit without being partially broken.

In the cutting step, a portion where no slit is formed near one end in the width direction of the continuous release paper is provided, and a linear slit is formed in the remaining portion in the other width direction. In particular, when a continuous release paper having a relatively narrow width or a continuous release paper having a marginal punch hole provided only on one side is applied, it is effective because it is easy to cut and the adverse effect of forming a slit is small.

In the cutting step, when a portion where no slit is formed near both ends in the width direction of the continuous release paper and a linear slit is formed in the remaining portion in the other width direction, This is effective because, when pasting continuous release paper having a general width, such as for a delivery slip, no trouble such as turning over of the edge occurs.

Further, in the cutting step, a portion where no slit is formed near both ends and near the center in the width direction of the continuous release paper, and a linear slit is formed in the remaining portion in the other width direction. In particular, when sticking a relatively wide continuous release paper, there is no problem such as widening from the slit portion, so that it can be stably stuck, which is effective.
