Abstract

PROBLEM TO BE SOLVED: To eliminate collapse caused by winding deviation by aligning a plurality of narrow non-adhesive tapes around a winding core in a rolled state and collectively winding them. SOLUTION: A collective roll tape 11 is so formed that a plurality of narrow- width non-adhesive tapes 13 are aligned around the outer circumference of a winding core 12 in a rolled state. In this case, the core 12 which is composed of a paper tube, a metal core such as aluminum, a synthetic resin core, etc., is set to equal to or longer than the collecting width of a parallel-arranged non-adhesive tape 13 group. The winding-start tip of each non-adhesive tape 13 is fixed to the core 12 by a pressure sensitive adhesive double coated tape and the winding-end tip is also fixed by the pressure sensitive adhesive double coated tape in the same way. The core 12 is thus set long and each tape 13 side face is superposed on each other so that the roll-end attitude of each non- adhesive tape 13 can be surely held.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a narrow-width collective tape capable of forming a narrow-width non-adhesive tape into a roll, and a method of manufacturing the same.

[0002]

2. Description of the Related Art For example, an elastic narrow tape is used for cushioning a frame of a display such as a notebook personal computer or a word processor.

As such a tape, a tape having a width of 2 to 3 mm and a narrow width is used, and precision of width is particularly required.

FIG. 5 shows an example of the cross-sectional structure of the tape. A double-sided pressure-sensitive adhesive layer 2 is provided on one side of an elastic tape 1 using silicone rubber or the same synthetic resin.
Has a cross-sectional structure in which is protected by a separator 13 made of PET or the like so that the separator 3 is peeled off at the time of use, and the elastic tape 1 is affixed to a target portion with an adhesive layer 2. In state 4, both surfaces are non-adhesive.

In a conventional tape manufacturing method, a roll wound tape is manufactured by rotating an original roll obtained by rolling a sheet serving as a tape material around a paper tube and cutting the original at a predetermined interval with a slitter blade. ing.

[0006]

However, when a non-adhesive narrow tape is manufactured by the conventional manufacturing method as described above, since the tape is narrow, as shown in FIG. 4 (B), since the tape overlaps with each other because the overlapping surface of the tape is not sticky, the roll 4 is broken by the roll gap 7, and the roll 4 is broken. It was not possible to maintain a rolled appearance, and thus it was not possible to produce a non-adhesive, narrow tape in roll form.

[0007] For this reason, at present, conventional non-adhesive, narrow tapes are manufactured by punching out a sheet using a blade.

[0008] In recent years, however, the demands of users for the above-mentioned tapes are high-precision, long, low-cost products, and production by punching cannot meet any demands in any aspect.

An object of the present invention is to provide a non-adhesive, narrow tape which can be held in the form of a roll, and which can produce a long product with high precision in the width dimension at low cost. An object of the present invention is to provide a collective winding tape and a method for manufacturing the same.

[0010]

Means for Solving the Problems In order to solve the above-mentioned problems, the invention of claim 1 employs a configuration in which a plurality of narrow non-adhesive tapes are wound around a core in a rolled state. It was done.

According to a second aspect of the present invention, there is provided a construction in which a running non-adhesive sheet is cut into a narrow tape by a slitter, and the tape is wound around a core at different positions for each of a plurality of parallel units. It has been adopted.

The non-adhesive tape has a cross-sectional structure in which a separator is superimposed on a double-sided pressure-sensitive adhesive layer provided on one surface of an elastic tape, and when wound on a paper tube or an aluminum core, the winding end is a double-sided tape. At the same time, the terminal at the end of the roll is also affixed with double-sided tape to maintain the rolled appearance.

[0013] Further, the tapes wound collectively on the core do not collapse due to the slippage due to the side faces overlapping each other, and the core is widened by the number of tapes and does not slip out or collapse.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 (A) and 1 (B), the collective winding tape 11 has a narrow width non-adhesive tape 1
3 is formed by being wound so as to be lined up in a roll wound state, the width W of the non-adhesive tape 13 is about 2 to 3 mm,
The number of collective windings is arbitrary, but is, for example, about 3 to 5 windings.

As shown in FIG. 5, the non-adhesive tape 13 comprises an elastic tape 1, a double-sided pressure-sensitive adhesive layer 2, and a separator 3.
The core 12 is made of a paper tube, a metal core such as aluminum, a synthetic resin core, or the like, and is equal to or longer than the set width of the non-adhesive tapes 13 arranged in parallel. .

The winding start end of each of the non-adhesive tapes 13 with respect to the core 12 is fixed to the core 12 with a double-sided adhesive tape, and the other end of the winding end is also fixed with a double-sided adhesive tape.

The collective winding tape 11 has a plurality of narrow non-adhesive tapes 13 arranged side by side, and the side surfaces of the tapes 13 overlap with each other.
Is long, so it does not collapse or fall out.
And the roll winding posture can be reliably maintained, and the roll winding can realize the elongation of the ultra-fine tape.

FIGS. 2 and 3 show a method of manufacturing the collective winding tape 11, wherein the sheet 14 is pulled out from a raw material 15 obtained by rolling a sheet 14 which is a material of a non-adhesive tape having a narrow width. A slitter device 23 is provided on the way to guide and travel sequentially from 16 to 22, and the sheet 1 passing therethrough is provided.
4 is cut into a narrow width by the slitter 23,
A winding section 24 of a narrow tape near the roller 22 at the final end,
24 are provided.

As shown in FIG. 2 (B), the slitter device 23 comprises an upper blade 27 having a number of disk-shaped blades 26 attached to a rotating shaft 25 at regular intervals, and each blade 2 of the upper blade 27.
6 is a combination of a disk body 28 in contact with the side surface of the blade edge and a lower blade 30 arranged at a fixed interval on a shaft 29, and the sheet 14 passes between the upper blade 27 and the lower blade 30 so that the blade The sheet 14 is cut at an interval L of 26, and a large number of narrow tapes are cut out at the same time.

Accordingly, the interval L between the blades 26 is the width of the narrow tape, and the interval L is set to, for example, about 2 to 3 mm.

The narrow tape winding units 24, 24 are provided in a zigzag arrangement on a plane such that a plurality of narrow tapes arranged in parallel are taken as a unit and the adjacent units are wound alternately on both sides. ing.

Specifically, as shown in FIG. 2A, two winding shafts 31, 31 are arranged in parallel at a distance on both sides, and the two winding shafts 31, 31 are wound around the two winding shafts. The cores 12 are mounted so as to be alternately arranged on both sides at regular intervals, and the narrow tape coming out of the roller 22 at the final end is wound into a corresponding number of cores 12 by a predetermined number of units. Thus, the collectively wound tape 11 shown in FIG. 1 can be manufactured.

By the way, if the sheet 14 has a width of 125 mm and is cut into narrow tapes of 2 mm or 2.5 mm in width and wound in a group of five narrow tapes, a collective winding tape Can be manufactured simultaneously.

[0025]

As described above, according to the present invention, by forming a non-adhesive ultra-thin tape into a collective winding, no collapse occurs due to misalignment of the tape, and the core becomes longer. Is eliminated, and it is possible to commercialize a narrow-width tape in a rolled state, and the realization of the roll-winding makes it possible to lengthen the narrow-width tape.

Further, the process from cutting to winding of the narrow tape can be performed mechanically, and the cost can be reduced by automating the production of the collectively wound tape.
