Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 In the present invention, when a sheet-like material such as a synthetic resin film is wound into a roll-shaped roll, a tapping tape is spread between the final layer or several layers of the roll-wrapped sheet so that the tail end can be easily peeled off. The present invention relates to a structure of a rolled sheet having a lead-out tape which is inserted in the central portion of the direction and whose end is exposed, and particularly to the structure of the lead-out tape.

[0002]

[Prior art]

 . Conventionally, when a sheet-like material having adhesiveness such as a single-sided adhesive tape or a sheet-like material having physical self-adhesiveness such as polyethylene film is wound into a roll under appropriate tension, the end of the unwinding end is directly below. It is well known that it has the inconvenience of adhering to layers and not being easily peeled off.

Therefore, in such a case, it is possible to eliminate the above-mentioned inconvenience by inserting a lead tape on the final one-roll layer or several-roll layer, and some devices have already been proposed. However, in the case of narrow rolled sheets, there is no problem if a small length of lead tape is inserted, but in the case of a wide film used for packaging seals, the entire width is covered. Since it is possible to increase the cost by increasing the number of materials to insert the output tape for a considerable length, it is adopted to insert the output tape having an extremely narrow width as compared with the sheet-like material. The method disclosed in Japanese Utility Model Publication No. 54-26360 is proposed, that is, a sheet P such as a synthetic resin film is wound around a roll 1 as shown in FIGS. Sheet When S is obtained, before the end of the constant length winding leaving one or several winding layers, an output tape T having an extremely narrow width as compared with the sheet P is fed to the winding center position of the width center of the sheet P, A technique has been put into practice in which the end portion Ta of the sheet P is protruded from the tail end of the sheet P, and the slightly tail end P'of the rolled sheet S is bent together with the tape T.

[0004]

[Problems to be Solved by the Invention] However, the rolled tape sheet obtained by the above method has a relatively small friction resistance such as normal paper or cellophane, and therefore the rolled tape is used as a sheet. If the operator pulls only the bent end Ta of the output tape without pinching and pulling it together with the bent portion P ′ of the winding tail, only the output tape T slips through and the winding end of the bent corner cannot be reliably peeled off. is there.

Therefore, the present invention pays attention to such an actual situation, and further improves the material of the output tape so that even if only the bent end of the output tape is pulled, the tape does not slip through and the winding tail of the sheet is always kept. The purpose is to easily peel off together with the bent portion of the end, and to ensure peeling of the rolled sheet.

[0006]

[Means for Solving the Problems]

 That is, according to the present invention which meets the above-mentioned purpose, the above-mentioned sheet is wound around a roll, a tape is inserted at the tail end of the sheet, and the end of the sheet is bent along with the length of the tail end of the sheet to expose it. In the case of a rolled sheet, the tape is inserted by using a tape having at least a tape surface subjected to a treatment for increasing frictional resistance against the tape as the tapping tape and preventing the tape from slipping through.

[0007] Here, the process of increasing the frictional resistance with respect to the sheet means a process of being inserted between the sheets and peeled off together with the sheets. Specifically, a resin coating such as vinyl chloride coating is generally used. . However, it is not limited to resin, and processing such as fine powder coating is also possible, and flocking tape can be used.

[0008]

[Embodiment of device]

 Hereinafter, specific embodiments of the present invention will be described. The present invention relates to the output tape T in the rolled sheet material S as shown in FIGS. 1 and 2, as described above, in which the sheet P is wound around the roll 1 and the output tape T is inserted in the winding tail portion. The structure of the rolled sheet itself, which is inserted and bent at the end portion Ta with a slight length P'of the rolled sheet tail portion and exposed on the outer surface, is similar to the conventional rolled sheet material.

However, in the present invention, the tape used as the output tape T is treated on the tape surface so that the frictional resistance against the sheet is great, and when the bent end Ta of the output tape is pulled, the tape is applied to the outer surface of the output tape T. Both the sheets P that come into contact with each other can be easily peeled off.

Various treatments such as a synthetic resin coating on the tape surface, a flocked tape with flocked surface, or a fine concave-convex surface on the tape are applied as the treatment for increasing the frictional resistance to the sheet. Although possible, the most simple and practical treatment is resin coating such as vinyl chloride resin coating. These surface treatments are sufficient only on the surface side that comes into contact with the output tape sheet, but it can be applied to both the front and back sides as long as it does not cause any problems. However, the preferred embodiment is the treatment of only the tape surface.

In this way, when the output tape whose surface has been treated to have a large frictional resistance is used, even if only the end of the output tape is pulled, the sheet in contact with the surface is frictionally slid. By joining them together, they are joined together and peeled off together, and only the tape does not slip through, and the conventional problems are solved.

[0012]

[Effect of device]

 As described above, the present invention is a tape having a surface treated so as to have a large friction resistance against the sheet as an output tape inserted at the tail end of the rolled sheet, and the large friction of the tape surface Even if only the bent end of the extra-thick lead tape is pulled by the resistance, only the tape does not slip through, the sheet and tape peel together, and the unwinding tail of the rolled sheet can be easily and reliably separated. It has a remarkable effect. The present invention is particularly effective when applied to the dissociation of a rolled sheet made by rolling a packaging film such as a polyethylene film.
