Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manufacturing method for obtaining a plurality of small-piece labels in a state of being collected.

[0002]

2. Description of the Related Art With the recent widespread use of electrostatic printing machines, it is possible to print information on a blank label using this electrostatic printing machine and easily obtain a label having machine-printed information. Under such circumstances, a sheet material provided with a plurality of unit label sheets in the form of small pieces that can be peeled off has been provided. FIG. 3 shows an example thereof, which is a sheet material in which a release paper 2 is attached to the back surface of a label sheet 1.
In the label sheet 1, a plurality of unit label papers 4 are formed by notches 3 reaching the adhesive on the back surface of the label sheet 1.
It is designed such that information can be printed on each of the unit label sheets 4 at once by loading the sheet material into the electrostatic printing machine.

FIG. 4 shows a method of producing the unit label paper. As shown in the drawing, a roll paper 6 is formed by a base paper 5 obtained by releasably attaching a release paper to the back surface of the label sheet 1.
The base paper 5 in the form of a strip is punched out from the label sheet side with a cutting blade reaching the adhesive from the label sheet side, and a plurality of unit label papers 4 are divided in the label sheet 1 of the strip-shaped base paper 5 by the cuts 3. Form. In the next step, the side edges of the base paper 5 are cut by the slitter 7 and the unit label is cut by the cutting machine 8 in order to make the formation area of the unit label paper have a required width, that is, to obtain a sheet product having a required width. Sheets of the required size and shape are obtained by stacking each sheet forming area.

[0004]

FIG. 5 shows the cutting by a cutting machine for obtaining the above-mentioned sheet material. That is,
A state in which both the label sheet 1 and the release paper 2 that covers the back surface of the label paper 1 in a peelable manner are cut by a cutting blade 9 extending in a direction perpendicular to the feeding direction of the base paper in order to obtain a sheet having a required size and shape. In each cutting, the adhesive or the paper powder 10 adheres to the cutting edge of the cutting blade 9 and accumulates, which deteriorates the sharpness of the blade or makes it impossible to cut the sheet material. Each time, the adhesive and paper dust are removed from the cutting edge and the cutting blade itself is replaced. Adhesion and accumulation of such adhesives and paper powder also occur in the above-mentioned slitter, and the same treatment as that of the cutting blade is required.

When cutting is performed with the adhesive or paper dust attached to the blade edge, the adhesive or the like easily attaches to the side portion of the label sheet, and the sheet material in this state is electrostatically printed as described above. When loaded in the machine, the adhesive, etc. may further adhere to the drum of the electrostatic printing machine, resulting in missing print when printing on the unit label paper. There is also a problem in that the sheets are adhered to each other by the pressure-sensitive adhesive and the paper is fed to cause double feeding.

In view of the above circumstances, it is an object of the present invention to prevent an adhesive or paper dust from adhering to the cutting edge during slitting or cutting when a sheet having a desired shape and size is obtained. The purpose is to eliminate omissions and double feeds.

[0007]

The present invention has been made in view of the above-mentioned problems, and reaches the pressure-sensitive adhesive from the label sheet side to a base paper in which the pressure-sensitive adhesive on the back surface of the label sheet is covered with release paper. Put a notch, while forming a plurality of unit label paper by the notch in the label sheet, and make a notch reaching the adhesive from the label sheet side around the formation area of the unit label paper, the label The sheet is divided into a forming surface portion and a non-forming surface portion of the unit label paper, and the label sheet of the non-forming surface portion is lifted up to expose the release paper to the side of the forming surface portion,
A method for producing a unit label sheet, characterized in that the exposed release paper is cut off leaving a portion along a side of a forming surface portion, and an overhanging portion made of release paper is provided along a side of the forming surface portion. Then, the above-mentioned problems are solved.

[0008]

In the present invention, since the non-formed surface portion is scraped up from the notch provided around the formed surface portion of the unit label paper, the label sheet of the non-formed surface portion can be removed from the release paper together with the adhesive. Since the release paper exposed around the forming surface portion is cut off so as to leave the overhanging portion along the side of the forming surface portion, adhesive or paper dust does not adhere to the cutting blade or slitter for cutting. Like

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to an embodiment shown in FIGS. The parts having the same configurations as those of the conventional example shown in FIGS. 3 to 5 are designated by the same reference numerals, and the description thereof will be omitted. FIG. 1 shows one embodiment of the method according to the present invention in the order of the steps thereof.
Label sheet 1 for strip-shaped base paper 5 pulled out from
Die cutting a is performed by a cutting blade reaching the adhesive from the side, and the label sheet 1 on the band-shaped base paper 5 is cut by the cutting 3.
A plurality of unit label papers 4 are formed inside. Although the unit label papers 4 shown in the figure are provided in a state of being separated from each other, the unit label papers 4 may be connected to each other as lattice-shaped cuts.

In the next step, in order to define the formation area of the unit label paper 4, a frame-shaped die-cutting b is performed along the periphery of the formation area with a notch 11 reaching the adhesive from the label sheet 1 side, The label sheet 1 is divided into a forming surface portion 12 that holds a plurality of unit label sheets 4 and a non-forming surface portion 13 around the forming surface portion 12.

Next, the label sheet of the non-formation surface portion 13 is lifted up c to expose the release paper 2 around the formation surface portion. After that, in order to make the sheet material to be obtained have a required width, it is exposed at the side edges of the base paper 5 in the scraped-up state, that is, the side portions extending in the length direction (upper side and lower side in the figure). The slitter 7 is applied to the release paper 2, and the side of the forming surface portion 12 in the length direction of the base paper (that is, the forming surface portion 12).
The excess release paper 2 is cut off so that the overhanging portions 14 along the upper and lower sides remain. In this way, the slitter 7 cuts the position away from the forming surface portion 12 of the label sheet 1 by providing the pouring portion 14, so that it does not come into contact with the adhesive.

First, the cutting surface 8 separates the forming surface portions 12 in a continuous state by the strip-shaped release paper. In this step, the cutting blade 9 corresponds to the front and rear sides of the forming surface portion 12 in the length direction of the base paper,
Release paper 2 exposed from the front and rear sides
The excess release paper 2 is cut off so that the overhanging portions 15 along the front and rear sides remain. As a result, the sheet material has the required shape and size, and the forming surface portion 1
2 has the pouring parts 14 and 15 around it. Even in this cutting, the cutting blade 9 cuts at a position away from the forming surface portion 12, and therefore does not come into contact with the adhesive.

[0013]

According to the present invention described above, when a sheet material including a plurality of unit label paper sheets is formed into a desired shape and dimension, an overhang portion made of a release paper is provided around the formation surface portion of the unit label paper sheet. Therefore, the edge of the slitter or cutting blade does not come into contact with the adhesive on the label sheet,
Prevents adhesive and paper dust from adhering. Therefore, the adhesive or paper dust does not adhere to the label sheet side from the cutting edge, the sheet materials do not adhere to each other at the time of loading in the printer, and they do not adhere to the drum side of the printing machine. This has an effect of excellent practicality, such as no printing omission on the upper side (on the unit label paper).
