に巻き取って製造していた。BACKGROUND OF THE INVENTION Adhesive tapes include single-sided adhesive tapes without a release sheet and single-sided or double-sided adhesive tapes with a release sheet. In the case of attachment, it is manufactured by winding it together with a release sheet on a paper tube or the like, and cutting the wound adhesive tape into tapes of a predetermined width in round slices. Each manufacturing method will be specifically described with reference to FIG.
As shown in, the single-sided adhesive tape 20 without the release sheet is
Adhesive is directly or indirectly applied to the tape base material 21 that has been treated to make it difficult for the adhesive to adhere to one surface, to form a two-layer structure consisting of the tape base material and the adhesive layer 22, and a paper tube or the like. It was rolled up and manufactured.

0 is a double-sided release sheet 23 whose both sides have been subjected to an easy release treatment, coated with an adhesive on one side, and the tape base material 21 is bonded to the surface of the adhesive coated on the double-sided release sheet, and the ordinary adhesive is applied. By applying the agent directly or indirectly to the surface of the release sheet or tape base material on which the ordinary adhesive is not adhered, the double-sided release sheet 23 / adhesive 22 / tape base material 2
1 / Adhesive 22 was formed into a four-layer structure and wound around a paper tube or the like to manufacture.

易であった。As can be seen from FIGS. 3 and 4, when these tapes are wound around a paper tube or the like, in a single-sided adhesive tape without a release sheet, the adhesive coated on the tape base material is one inner layer. It is bonded to the surface of the tape base material on the side that has been treated to make it difficult for the adhesive to adhere, and adheres to this surface. Further, in the double-sided pressure-sensitive adhesive tape with a release sheet, the pressure-sensitive adhesive coated on the tape base material is one surface of the release sheet provided with the pressure-sensitive adhesive on the tape base material on the inner layer side. Bonding occurs, and also here, adhesion between the release sheet and the tape substrate occurs. In this way, since the inner and outer layers of the wound tape are subjected to an easy peeling treatment, etc., they are weaker than the adhesive strength of the tape base material and the adhesive, but they are sticky to some extent and do not slip. Therefore, the winding state is maintained without causing the collapse of the winding. Therefore, when manufacturing a tape having a narrow width by cutting a wide material into a predetermined width, it is possible to manufacture these tapes by cutting the material wound around a paper tube into a ring slice. It was easy.

る。However, as shown in FIG. 5, in the one-sided pressure-sensitive adhesive tape 40 with a release sheet, a normal pressure-sensitive adhesive is applied to the surface of the release sheet 23 which has been subjected to the easy-release treatment, and then the tape base material is joined. The release sheet 23 and the tape base material 21 have a three-layer structure in which the pressure sensitive adhesive 22 is sandwiched between the release sheet 23 and the tape base material 21 and are wound on a paper tube or the like to be manufactured. Since the surface of the tape base that does not have the adhesive adheres to the surface of the release sheet that does not have the adhesive, the contact surface is slippery and naturally collapses. Is likely to occur.

片面粘着テープ原反をそのまま輪切りに切断する方法で
は、切断の際にかかる力によって巻きずれを生じ、一定
の幅に切断することは困難であった。Therefore, when a single-sided pressure-sensitive adhesive tape having a wide release sheet is cut to produce a single-sided pressure-sensitive adhesive tape with a release sheet having a predetermined width, a single-sided pressure-sensitive adhesive tape without a release sheet and a double-sided pressure-sensitive adhesive tape can be used. In the method of cutting the wound single-sided pressure-sensitive adhesive tape raw material into circular slices as it is, it was difficult to cut into a constant width due to winding deviation due to the force applied at the time of cutting.
【0007】そのため、幅の狭い剥離シート付きの片面

いた。Therefore, when manufacturing a single-sided adhesive tape with a narrow release sheet, the slitting device is used to unwind the single-sided adhesive tape with the release sheet wound on a paper tube to a predetermined width. Manufacturing by cutting into multiple tapes and winding each tape around another paper tube, or by piercing a roll wound around a paper tube with a nail or roughening the tape surface It was manufactured by cutting it into round slices as it is to prevent winding misalignment.

壊につながる上に、手作業に使用される場合が多いこと
も原因して巻き崩れを起こしやすいものであった。The single-sided pressure-sensitive adhesive tape with a release sheet produced in this manner is very slippery, and particularly in the case of a tape having a narrow width, even a slight displacement due to a lateral force will cause collapse of the winding and also manual work. Due to the fact that it is often used, it was prone to collapse.

ける作業をしなければならなかった。Therefore, the work of sticking these one-sided adhesive tapes with release sheets, which are likely to be rolled up, is performed while holding the one-sided adhesive tapes with release sheets with one hand while preventing the rolls from collapsing, and at the same time pinching the release sheet and holding the other hand. Therefore, it was necessary to attach a tape base material having an adhesive coated on one surface to an object.

い。However, the method of using a slitting device for producing an adhesive tape with a release sheet having a narrow width from a single-sided adhesive tape stock with a release sheet is more complicated than a process of cutting into a circular slice as it is. And it requires a long time, a large energy requirement,
Moreover, since the equipment cost of the slitting device is large, an increase in manufacturing cost cannot be avoided, and it is used only in special cases.

損失が生じていた。Further, a method of cutting the raw fabric as it is by applying a nail or the like to the raw fabric of the single-sided adhesive tape with a release sheet to prevent winding misalignment by roughening the tape surface and cutting the raw fabric as it is is applicable. There is a limit to the thickness of the original fabric, and when cutting the original fabric, if the remaining amount of the original fabric decreases and the width decreases, it is no longer possible to prevent winding deviation, and the remaining portion should be discarded. There was no choice but to lose a lot of money.

うに製造せざるを得なかった。On the other hand, in the conventional one-sided pressure-sensitive adhesive tape with a release sheet, which is apt to collapse, as described above, the one-sided pressure-sensitive adhesive tape with a release sheet has to be attached to an object while preventing the one-sided pressure-sensitive adhesive tape with a release sheet from rolling. In consideration of workability, the manufacturing method had to be manufactured so as not to exceed the thickness of the circumference that can be held with one hand.

が生じていた。Therefore, it is difficult to manufacture a long tape, especially for a single-sided adhesive tape with a release sheet having a thick tape base material, and after the tape is attached to an object, the length of the remaining tape is the object. A large amount of unusable residue of a length that cannot be used shorter than the length was generated, resulting in waste of resources and energy.

危険性も大きかった。In addition, since the sticking work is a work method that requires the use of both hands without fail, the workability is poor and, for example, when it is used as a building exterior such as a gap prevention tape or a heat insulating tape to be stuck to a window frame. There was a great danger especially when working in high places.

ている。On the other hand, a single-sided adhesive tape with a release sheet is printed, and the tape base material is die-cut, for use as a seal or label, or for applying a pressure-sensitive adhesive porous material There are widely used applications such as a gap filling tape based on a tape substrate and an impact-absorbing packing inner tape, which must be a single-sided adhesive tape with a release sheet.

The surface not subjected to is formed from a resin layer having a property of being removably attached to the tape base material,
It is characterized in that it is bonded to the surface of the tape base material on which the usual adhesive is not formed.

としている。It can be seen that in order to prepare a wound body in which the winding is not broken by using the single-sided adhesive sheet with the release sheet, it is necessary to increase the adhesive force between the release sheet and the tape base material. If a normal adhesive is applied to the base material, the adhesive strength is too strong and it is not easy to attach the tape, and there are many inconveniences such as the adhesive remaining on the tape base material. It was not possible to use such an adhesive. The present invention can be re-peeled on a tape substrate such as a resin having a Vicat softening temperature of 0 ° C. or higher, which is not generally called an adhesive, or a re-peeling pressure-sensitive adhesive having an extremely low adhesive force, without using such an adhesive. It is characterized by using an adhesive resin having a property of sticking to the adhesive sheet to impart an adhesive force between the release sheet and the tape base material to prevent winding collapse.

る。The single-sided pressure-sensitive adhesive tape with a release sheet of the present invention has a structure as shown in FIGS. 1 and 2, and FIG. 1 shows a case where the release sheet is wound inside (hereinafter referred to as "inner winding").
2), and FIG. 2 shows a case where the release sheet is wound outside (hereinafter referred to as “outer winding”). As can be seen from the figure, when the single-sided pressure-sensitive adhesive tapes 1 and 2 with a release sheet of the present invention are considered as a wound body in a wound state,
In both cases of inner winding and outer winding, the easily peelable surface R of the single-sided release sheet 3 is joined to the tape base material 5 with the ordinary pressure-sensitive adhesive 4 sandwiched between them, and the easy release treatment of the release sheet 3 is performed. The surface not applied is made of an adhesive resin 6 having a property of being removably attached to the tape base material. On the other hand, when pulling back the tape and looking at the structure of the tape itself, the positional relationship between the release sheet and the tape base material is reversed,
For inner winding, the surface R of the single-sided release sheet 3 subjected to the easy release treatment
However, while it is bonded to the ordinary pressure-sensitive adhesive 4 formed on the tape base material, it can be re-peeled on the tape base material which is the surface of the single-sided release sheet 3 which has not been subjected to the easy peeling treatment in the outer winding. The adhesive resin 6, which has the property of sticking to, adheres to the surface of the tape base material 5 on the side where the adhesive layer is not formed.

着性が現れるものである。In the present invention, the reason why the adhesiveness is exhibited by a resin having a Vicat softening temperature of 0 ° C. or higher, which is not a pressure-sensitive adhesive, is not clear, but these resins form a hydrogen bond or an ionic bond with the tape substrate. It is considered that this is partly due to the weak bond such as and the generation of electrostatic attraction. Therefore, as the structure of the resin, a highly polar resin such as a styrene-acrylic copolymer containing a functional group or an epoxy-modified polyvinylidene chloride is preferable, and C═O or N is included in the molecule.
A resin that contains H and OH and is moist and sticky to the touch is suitable. However, the adhesiveness of these resins significantly changes depending on the material of the tape base material, and when the tape base material does not have a functional group that causes hydrogen bonding or ionic bonding, the Vicat softening temperature is 0 ° C or higher. Resin does not exhibit much adhesion. On the other hand, when the tape base material is soft vinyl chloride containing a large amount of highly polar plasticizer such as cresol phosphate or silicone resin containing a large amount of silicic acid units, epoxy modification with a Vicat softening temperature of 0 ° C or higher is performed. Polyvinylidene chloride and styrene-acrylic copolymers show remarkable adhesion. As described above, the present invention uses a resin having a Vicat softening temperature of 0 ° C. or higher,
Even if the resin surface on the release sheet is touched, there is almost no tackiness, and the adhesiveness appears only when it is pressed against a compatible tape substrate.

でも容易に製造することができる。According to the present invention, in the pressure-sensitive adhesive tape roll, the one-sided release sheet subjected to the easy-release treatment is bonded to the tape base material with the ordinary pressure-sensitive adhesive interposed therebetween, and the release sheet is subjected to the easy-release treatment. By forming the release sheet-attached single-sided adhesive tape of the present invention, characterized in that the surface not formed is a resin having a property of being removably attached to the tape base material, Adhesiveness can be imparted to the surface on which no pressure-sensitive adhesive is formed, and there is no fear of roll collapse. Therefore,
When manufacturing a single-sided adhesive tape with a narrow release sheet from a single-sided adhesive tape with a wide release sheet, there is no need to use an expensive slitting device, and the wound wide tape is cut into round slices as it is. It can be easily manufactured simply by In addition, it is not necessary to pierce the wound roll with a nail or the like to prevent the roll from collapsing, and almost the entire amount can be cut into a narrow single-sided adhesive tape with a release sheet. Furthermore, in the method to prevent roll collapse by sticking a nail,
Depending on the length of the nail that can be driven in, there was a limit to the length of the tape that can be wound up, but there is no such limit in the pressure-sensitive adhesive sheet with a release sheet of the present invention, and it is possible to easily manufacture even a thick tape with a long tape length. it can.

短時間で作業を完成させることができる。In addition, in the conventional work of sticking a single-sided adhesive tape with a release sheet that easily collapses, while holding the single-sided adhesive tape with a release sheet with one hand while holding it, the release sheet is pinched and the other hand is held. Therefore, it was necessary to attach a tape base material having a normal adhesive applied to one side to an object. However, in the work of sticking the one-sided adhesive tape with a release sheet of the present invention, there is almost no possibility that the one-sided adhesive tape with a release sheet will collapse, so that the tape is held with one hand without particularly preventing the collapse. It becomes possible to attach it to the target object just by itself, it is extremely efficient,
Work can be completed in a short time.

The release sheet remains attached to the surface of the tape base material that is not bonded to the normal adhesive, that is, remains attached to the outside of the tape base material attached to the object, and holds the tape without the need to remove the release sheet. It is possible to attach the tape directly to the target object with one hand, and the other hand can be used by the worker to maintain his posture,
The risk, especially in working at heights, is significantly reduced.

ルギーの節約になり、経済的である。Since the single-sided pressure-sensitive adhesive tape with a release sheet according to the present invention is less likely to cause winding collapse, even a long tape having a large winding diameter can be easily handled.
The length of the remaining tape is not enough for the length of the object to be pasted, and the number of short residuals that cannot be used is reduced. In other words, it reduces the amount of waste, saves resources and energy, and is economical.
