Description

DETAILED DESCRIPTION OF THE INVENTION (1) Object of the Invention (Industrial field of application) The present invention relates to a sticking device for sequentially sticking a wound long tape to an adherend. .

(Problems to be Solved with Prior Art) When only a tape is separated from a tape laminated member obtained by attaching a separator (lining member) to an adhesive tape and adhered to an adherend, conventionally, for example, As shown in the figure,
The tape stacking member T including the separator 1 and the tape 2 is pressed down onto the adherend 3 placed on the base plate 4 by the head 5 to press the tape at once. It has been customary to adhere the adherend 3 and then separate the separator 1 from the tape.

At the same time, since the tape has a flexible structure, such a sticking means has a structure such that the sticking surface and the head surface facing the sticking surface are warped, bent, uneven, etc. Inevitably, there is a drawback that air is enclosed between the attachment surfaces, which weakens the adhesive strength.

In order to avoid such drawbacks, the tape side of the tape laminated member is adhered and abutted to the adhering surface, and the separator head is squeezed to run the separator surface to adhere the tape to the adhering surface. Some of them are proposed, for example, in Japanese Utility Model Publication No. 51-6381.

However, in such a device, the tape head is cut while the tape head is cut by the cutter after the end attachment is completed by running the sticking head while the long tape stack member is in contact with the adherend surface, and the tape stack member and the cutter are cut. No matter what the arrangement of the tape is, it is impossible to completely match the position where the sticking head presses the tape stacking member with the position where the cutter cuts the tape. A tape that adheres to the surface to be adhered in the vicinity, a separator that separates from the tape and even separates the surface to be adhered, in other words, a separator that acts to peel the tape from the surface to be adhered, and a tape laminated member. It is possible to avoid the problem that the relational action between the sticking head that presses against the sticking surface as a whole does not match well and that the end of the tape remains peeled off after the sticking is completed. The fact is that there was no A.

The present invention has been made to cope with such a current situation, and when the tape is completely attached to the surface to be attached, the running of the tape is stopped and the tape to be attached next by the cutter is used. (EN) Provided is a sticking device capable of performing accurate and beautiful sticking by cutting a part so that a tape is already stuck to a separator and cut to a predetermined length when sticking. The purpose is.
