Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous label sheet in which a plurality of label sheets in which a pair of label sheets are releasably attached are connected to each other, and a method for producing the same.

[0002]

2. Description of the Related Art In recent years, there is a label paper in which label sheets, which are separated from each other by die-cutting or the like, are detachably attached to each other on the back surface coated with an adhesive, and required printing is performed. The printed label pieces are provided on the front and back sides without using release paper. And a single label paper with this pair of label sheets on the front and back is provided as a continuous label paper which is made by connecting a plurality of these, and this continuous label paper can be loaded into a printer or used together with other continuous paper. I am doing it.

FIG. 2 shows the continuous label paper 1 in which a pair of strip-shaped label sheets 3 each of which is capable of separating the label piece 2 by die cutting or the like are releasably attached with their back surfaces facing each other. The folding perforations 4 are formed in the width direction of the strip-shaped label sheet 3, and a plurality of single label sheets 5 are connected to each other through the folding perforations 4. To bond the pair of strip-shaped label sheets 3, as shown in FIG. 3 (A), adhesives 6 and 6 having different adhesive strengths are applied to the back surface of the strip-shaped label sheet 3, and the applied adhesives 6 and 6 are applied. The adhesive strength between the two makes it possible to attach them in a state of causing peelability, or
As shown in FIG. 3B, the adhesive 6 and the release agent 7 are alternately applied to the back surface of each strip-shaped label sheet 3, and the adhesive 6 of one strip-shaped label sheet and the release agent of the other strip-shaped label sheet are applied. 7 and 7 are attached so as to correspond to each other.

Further, in making the continuous label paper 1, the folding perforations 4 are punched as shown in FIGS. 4 (A) and 4 (B). That is, a plurality of sewing machine cylinders 9 having sewing machine blades 8 are arranged in the feeding direction of the belt-shaped label sheet while changing the vertical position, and a pair of belt-shaped label sheets 3 are passed between the sewing machine cylinder 9 and the receiving cylinder 10. A folding perforation 4 is formed in the folding perforation planned portion 11.

[0005]

As described above, the continuous label paper has perforations formed by a plurality of perforation cylinders whose positions are vertically changed. As shown in FIG. 5, the folding sewing machine is used for folding. This is to facilitate the valley fold a and the mountain fold b from the eye 4. That is, the place where the perforation blade is inserted from above with respect to the pair of strip-shaped label sheets fed in the lateral direction is the valley perforation perforation, and the place where the perforation blade is inserted from below is the perforation perforation for mountain folding. When a continuous label sheet having perforations is stacked in a box or the like, the portion having the perforations for the valley folds is valley-folded, and the folds for the mountain folds have the perforations. The part is mountain-folded and folded. In addition,
The arrow indicated by the symbol Y represents the direction in which perforations are inserted.

However, as shown in FIG. 5, when the folding perforations are punched, the adhesive 6 between the strip-shaped label sheets is on the opposite side of the folding perforation 4 from the cut face to the insertion surface 12. When the continuous label paper 1 is slightly protruded on the surface 13 and is folded as shown in FIG. 6, the adhesive 6 is exposed to the outside, and the folded continuous label paper is pulled out. When it is sent to a device such as a printer, the adhesive that comes out comes into contact with the guide plate of the paper feed mechanism and adheres, which piles up and impairs the smooth feeding of continuous label paper. Therefore, it is necessary to remove the adhesive from the sliding contact portion such as the feed plate as maintenance of the equipment.

In view of the above situation, the present invention has an object to prevent the adhesive from sticking out and adhering to the surface opposite to the insertion surface when the perforation for folding is perforated. It is an object of the present invention to make it possible to continuously and continuously feed continuous label paper by a feeding mechanism in a device such as a printer.

[0008]

The present invention has been made in consideration of the above-mentioned problems, and comprises a pair of strip-shaped label sheets which are releasably attached so that the back surfaces coated with an adhesive are opposed to each other, In a continuous label paper in which a plurality of label sheets are connected in the length direction of the strip-shaped label sheet via folding perforations formed in the width direction of the strip-shaped label sheet, the perforations for folding are punched. To provide a continuous label paper characterized in that a protective layer having a peeling property with respect to the pressure-sensitive adhesive is provided on the surface opposite to the inserting surface of the sewing machine blade. It will be resolved. Still another invention is a pair of strip-shaped label sheets that are releasably attached to each other with the back surfaces coated with an adhesive facing each other, and perforation perforations are formed in the width direction of the strip-shaped label sheet. When creating a continuous label paper in which a plurality of label papers are connected in the lengthwise direction of the strip-shaped label sheet through the folding perforations, at least on the insertion surface of the perforation of the perforation portion of the perforation for folding. On the opposite side, a protective layer having releasability with respect to the pressure-sensitive adhesive is provided in advance, and then perforations are formed in the folding perforation planned portion from the insertion surface side. A method of producing a continuous label sheet, which is a feature of the present invention, is provided to solve the above problems.

[0009]

In the present invention, the continuous label paper does not have an adhesive agent attached to the protective layer having peelability, and since the folding perforation is formed after the protective layer is provided, the sewing blade is inserted. The adhesive that sometimes wraps around to the protective layer side returns to the cut end face side when the sewing machine blade is removed.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an embodiment shown in FIG. That is, in the present invention, as shown in FIG. 1, the continuous label paper 1 has a protective layer 14 having a peeling property such as silicon or varnish on a surface 13 opposite to the insertion surface 12 of the folding perforation 4. Is provided by printing or the like, and the pressure-sensitive adhesive that easily comes out from the cuts of the folding perforations 4 does not adhere to the protective layer 14. Then, in order to produce this continuous label paper 1, in a pair of strip-shaped label sheets which are releasably stuck together, the surface 13 opposite to the insertion surface 12 of the perforated perforated portion 11 for folding is to be formed. After the protective layer 15 is provided in advance by printing or the like, the folding perforations 4 are punched from the insertion surface 12 side. As a result, even if the adhesive may wrap around to the protective layer when the sewing blade is inserted, the adhesive returns to the end face side of the perforation and remains on the protective layer 15 when the sewing blade is removed. Disappears. The protective layer may be provided on the insertion surface 12 side in consideration of the efficiency of the production process, or may be provided on the band-shaped label sheet before being laminated.

[0011]

As described above, the continuous label paper of the present invention is composed of a pair of strip-shaped label sheets which are adhered to each other so that the back surfaces coated with the pressure-sensitive adhesive are opposed to each other. A plurality of label sheets are connected to each other in the length direction of a strip-shaped label sheet through folding perforations formed across the width direction, and a perforation blade for forming perforations for folding is inserted. On the surface opposite to the surface, since the protective layer having a peeling property with respect to the pressure-sensitive adhesive is provided, the pressure-sensitive adhesive does not remain on the protective layer, When the continuous label paper is pulled out from the folded state, the folds are not adhered to each other smoothly, and the feed mechanism such as a printer smoothly flows.

Another aspect of the present invention is that a pair of strip-shaped label sheets, which are adhesively coated with their back surfaces facing each other and are releasably attached, have folding perforations extending across the width of the strip-shaped label sheet. At the time of making a continuous label paper in which a plurality of label sheets are pierced and are connected in the length direction of the strip-shaped label sheet through the folding perforations, at least the perforation blade of the folding perforation perforation planned portion A protective layer having releasability with respect to the pressure-sensitive adhesive is provided in advance on the surface opposite to the insertion surface, and then the perforation is planned to be perforated from the insertion surface side in the perforated portion for folding. It is characterized by installing, by this,
Adhesive that easily wraps around the protective layer when the sewing machine blade is inserted will also be pulled back when the sewing machine blade is removed, making it possible to obtain continuous label paper without adhesive on the protective layer. It has a great effect.
