1 is a schematic view showing an adhesive tape cutting device according to an embodiment of the present invention, and FIG. 2 is a sectional view of the adhesive tape used in the example shown in FIG.

The long adhesive tape 10 used in the example shown in FIG. 1 is formed by continuously forming a plurality of display portions 12 in a strip shape, and each of the display portions 12 is cut at the boundary between the display portions 12. It is configured so that one tape strip is formed.

The long adhesive tape 10 has a pressure-sensitive adhesive layer 16 formed on the back surface of the long tape base material 14 forming the adhesive tape 10 and a release agent on the front surface side of the tape base material 14. A layer 18 is formed, and a printing layer 20 is formed on a part of the surface of the tape base material 14 on the front surface side of the tape base material 14 between the tape base material 14 and the tape base material 14. The print layer 20 separates the boundaries of the display units 12 from each other.
Are formed at regular intervals between the respective display parts 12 so as to form

As shown in FIG. 2, the adhesive tape 10 is a tape base material such that the release agent layer 18 side and the pressure-sensitive adhesive layer 16 face each other and are temporarily attached before cutting and use. 14 is wound in a roll. In addition, on the surface of the tape base material 14 on the release agent layer 18 side, the thermosensitive coloring layer 2
2 is formed.

The adhesive tape 10 is wound in a roll shape, loaded into an appropriate adhesive tape unwinding portion 31 of the adhesive tape cutting device 30 shown in FIG. 1, and rolled into the unwinding portion 31. While the adhesive tape 10 is being rewound, it is transferred to the belt 32 that constitutes the first transfer means. The belt 32 is an endless ring wound around rollers 34 formed at appropriate intervals, and is configured to rotate in the transfer direction of the adhesive tape 10 by the rotational force of a motor 33 connected to the rollers 34. There is.

The belt 32 has a tape contact surface 32a which comes into contact with the surface of the pressure sensitive adhesive layer 16 of the adhesive tape 10 and is subjected to a releasing treatment so that the surface of the pressure sensitive adhesive layer 16 of the adhesive tape 10 becomes tacky. It is formed so as not to be completely adhered even if it is transferred while being carried. Also, this belt 32
Is formed wider than the width of the adhesive tape 10, and is formed so that the adhesive tape 10 can be accurately cut when it is cut further downstream without curling in the width direction. The belt 32 may be released by forming a release layer made of silicone resin or the like on the surface 32a for contact with the tape, and applying a release agent on the surface 32a for contact with the tape. A device (not shown) may be provided in the vicinity of the belt 32 so that the contact surface 32a of the belt 32 with the tape always has releasability.

In order to adhere lightly to the surface of the contact surface 32a of the belt 32 with the tape, a pressing roller 35, which is relatively elastic or flexible, is formed facing the contact surface 32a with the tape. At 35, the surface of the adhesive tape 10 is lightly pressed to the belt 32 side.

A cutter 38, which is a cutting device for cutting the adhesive tape 10 fed by the belt 32, which is the first transfer means, is formed in the vicinity of the direction changing portion 36 of the belt 32. Then, by operating the cutter 38, the adhesive tape 10 sent by the operation of the belt 32 and the roller 34 that constitutes the first adhesive tape transfer means constitutes a tape strip having an appropriate length. Thus, the boundaries between the display units 12 are continuously cut. The operation of the cutter 38 is performed by a sensor 39 such as a photo switch formed near the direction changing portion 36 or the cutter 38.
It suffices to perform this in response to the electric signal of.

The belt 40 forming the second transfer means is formed at a position relatively close to the cutter 38. The belt 40 is rotated by a motor 41 so that the tape strip 10a is moved downward at a constant interval from the vicinity of the cutter 38 to the attachment position, and the contact surface with the tape strip 10a. 40a is inclined toward the attachment device. And the belt 40 is
In the vicinity of the sticking portion where the display unit 12 is stuck to the sticking object A, the roller 42 is wound around and rotated so as to have a substantially front acute angle shape.

Further, the tape of the belt 40 is attached to the belt 40 so that the tape strip 10a can be fed while being in contact with the surface of the pressure-sensitive adhesive layer 16 of the striped tape strip 10a while lightly adhering the tape strip 10a. The adhesive surface 40a with the strip 10a is subjected to a releasing treatment similar to that of the first transfer means.
The contact surface 40 of the belt 40 with the tape strip 10a
To lightly adhere the tape strip 10a to the surface of a,
A pressing roller 43 having a relatively high elasticity or flexibility is formed so as to face the belt 40, and the pressing roller 43 is configured to lightly press the surface of the tape strip 10a.

The tape strip 1 sent by the belt 40

Therefore, the tape strip 10a sent by the belt 40 has the display portion formed by the coloring of the thermosensitive coloring layer 22 and can be attached to the adherend A. The timing of sticking to the adherend A is controlled by controlling the rotation of the belt 40 by an electric signal from a sensor 45 such as a photo switch.

When a delayed tack type adhesive is selected as the pressure sensitive adhesive layer of the adhesive tape 10, the first transfer means does not need to be released, but It is necessary to form an activation device that heats and activates the delayed tack type adhesive during the transfer in the transfer means, and activates the pressure-sensitive adhesive layer of the tape strip to give tackiness. There is.

The present invention can be variously modified without being limited to the above embodiment. For example, as shown in FIG. 3, innumerable convex portions 6 are scattered on the surface of the contact surface 62a of the adhesive tape 10 of the belt 62 as the first transfer means.
