本発明はロールからの巻き戻し性が良好で、し
かも被着体面に貼着後剥離テープの除去が簡単な
ロール状両面接着テープの巻き戻し方法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for unwinding a roll-shaped double-sided adhesive tape, which has good unwinding properties from a roll and also allows easy removal of the release tape after adhering to the surface of an adherend.
両面接着テープは、指圧程度の圧力で物品を目
的とする被着体面に強固に接着できるので汎用さ
れている。 Double-sided adhesive tapes are widely used because they can firmly adhere articles to the intended adherend surface with pressure similar to finger pressure.
これまで、両面接着テープの接着層を保護する
のに用いられている剥離テープは、クラフト紙の

テープを仮着してなる両面接着テープを用いると
物品又は被着体面と両面接着テープとの界面の有
効接着面積が減少し、充分な接着強度が得られな
いという欠点があつた。 Until now, release tapes used to protect the adhesive layer of double-sided adhesive tapes are made by forming a thin plastic layer on both sides of a paper base material such as kraft paper, and forming a release treatment layer on top of this. things dominate. The surface of this release tape has minute irregularities due to the surface shape of the paper base material, and since these irregularities are transferred to the adhesive layer, a double-sided adhesive tape made by temporarily attaching such a release tape is used. When used, the effective adhesion area at the interface between the article or adherend surface and the double-sided adhesive tape decreases, resulting in a drawback that sufficient adhesion strength cannot be obtained.

ある。 This disadvantage becomes more noticeable when the article to be adhesively fixed is an automobile emblem or side molding, and the adherend surface is a curved surface.

があつた。 Therefore, attempts have been made to use a plastic film, such as polyethylene or polypropylene, which has a weak affinity for the pressure-sensitive adhesive layer, as a release tape, instead of the above-mentioned paper material. Since the release tape made of such a film has a smooth surface, the surface of the adhesive layer after peeling also becomes a mirror surface, thus eliminating the above-mentioned drawbacks. However, to remove the release tape after it has been rewound and attached to the surface of an article or adherend via the exposed pressure-sensitive adhesive layer, the tape can be removed by peeling off the end with a pin to create a grip, or by Alternatively, it is necessary to perform a complicated operation such as attaching a strong adhesive tape to the end of a release tape and peeling it off.

生じるものである。 In order to solve the trouble of removing the release tape, a release tape with a release treatment layer formed on one surface of the plastic film is used, and the treatment layer of the tape is temporarily attached to the double-sided adhesive tape, and then the treatment is performed. I tried winding it into a roll with the layers inside.
The double-sided adhesive tape with release tape formed in this way can be easily removed after it has been applied to an article or adherend surface, but when unwinding, as shown in the figure, the release tape can be easily removed. There is an inconvenience in that the release tape temporarily attached to the inside of the double-sided adhesive tape that is being rolled is peeled off from the roll of double-sided adhesive tape and hangs in a peeled state on the back side of the adhesive tape that is being rewound. As unwinding progresses, the tape becomes longer and completely covers the back side of the adhesive tape.

た状態で巻き戻してなることである。 The present invention provides a novel method for unwinding a rolled double-sided adhesive tape using a release tape formed with a release treatment layer on one side, and the gist thereof is as follows: , a double-sided adhesive tape comprising a pressure-sensitive adhesive layer on both sides of a tape-shaped support, and an untreated side of a release tape comprising a release-treated layer on one side of a plastic film that has a weak affinity for the adhesive layer. In the double-sided adhesive tape obtained by temporarily attaching the adhesive layer and rolling it into a roll with the treated layer on the outside, the outermost release tape is removed and the adhesive layer and the treated layer are rewound with the adhesive layer temporarily attached. It is what happens.

ものである。 According to the present invention, since the outermost portion of the release tape is removed, the surface side adhesive layer of the double-sided adhesive tape is exposed when unwinding from the roll tape.
The adhesive layer on the back side is protected by a release tape, that is, the adhesive layer and the treated layer are temporarily attached.The length of the release tape is shorter than that of a double-sided adhesive tape due to the radius of curvature, When both are unwound in the same way, the release tape is given greater tension than the double-sided adhesive tape, and that tension is applied toward the center of the tape roll. The release tape temporarily attached to the back side of the tape will not sag.

なるものが用いられる。 The tape-shaped support used in carrying out the present invention may be a rubber and/or synthetic resin foam sheet or film, nonwoven fabric, cloth, paper, etc., and the pressure-sensitive adhesive layer may be a rubber and/or synthetic resin foam sheet or film. The main ingredient is a substance that has pressure-sensitive adhesive properties at room temperature. Release tapes include plastic tapes such as polyethylene tapes, polypropylene tapes,
A tape made of ethylene-vinyl acetate copolymer or the like coated with a release agent such as a long-chain alkyl acrylate copolymer, a silicone resin, or a fluororesin is used.

た状態で巻き戻されるものである。 The double-sided adhesive tape constructed in this way and the non-treated surface of the release tape are overlapped, and the release layer of the release tape is rolled into a roll on a paper tube or the like, with the release layer facing outward, and exposed. The outermost release tape is removed, and the tape is rewound with the adhesive layer and treatment layer temporarily attached.

てもよいものである。 However, the release tape on the outermost periphery may be temporarily attached without being peeled off until just before use, and then removed immediately before use. For this purpose, perforations etc. are made at the outermost edge of the release tape. It is a good idea to provide one.
