Abstract

<P>PROBLEM TO BE SOLVED: To form a non-adhesive part easily peelable afterward by folding the end part of an adhesive tape inside an adhesive surface. <P>SOLUTION: Right before cutting the tape, parts to be stuck are provided in two points in the end part of the tape and an intermediate position of a peeling position of a winding tape and, when a cutter where the tape end is stuck is moved in the peeling position, the adhesion part of the tape is rotated simultaneously when one side or both-side rotors stuck with the tape are slightly rotated, and the tape is curved with the adhesive surface facing inside. When the cutter is further moved to the peeling position, the curve becomes hard and the adhesive surface approaches. The non-adhesive part can be formed in the end part of the adhesive tape by picking it between fingers. <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to bending an end of an adhesive tape so that the tape having an adhesive adhered to one side thereof can be easily peeled off after attaching the adhesive tape to each other to bond the adhesive surface.
[0002]
[Prior art]
Conventionally, there is an application in which the end is bent as in Japanese Patent Application Laid-Open No. 08-113415, but it is very difficult to bend to the adhesive surface due to the strong refraction that occurs on the opposite side of the adhesive of the tape when the tape is separated from the winding of the tape. Was unstable.
[0003]
[Problems to be solved by the invention]
In the case where the end of the adhesive tape is bent and the adhesive portion is adhered, there has been a curl in which the adhesive surface is outward, but a reverse curved surface in which the adhesive surface is inward must be made.
[0004]
[Means for Solving the Problems]
In order to achieve the above purpose, after cutting, the part where the end of the tape is adhered is brought close to the part where the tape is adhered, and the round part is formed. At that time, the adhesive part rotates (one or both). By inclining, the roundness with the adhesive surface inside is formed smoothly.
[0005]
According to the present invention, when the pressure-contact portion of the adhesive tape is provided at two places at the end of the tape (position of the cutting device) and in the middle thereof, one or both of the rotating tapers are inclined with the rotation axis, and the cutting device is moved to the middle of the tape. By rotating and tilting the rotator along the tape (or in conjunction with the movement of the cutter), the tape adhered to the rotator smoothly forms a curved surface with the adhesive surface inside.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows a side view of the entire adhesive tape cutting machine. The two adhesive parts 5, 6 for pressing the adhesive tape together are rotators. In the figure, the cutting device is pressed by a finger and the tape end is rounded.
[0007]
The operation sequence in which the tape in FIG. 1 is rounded will be described with reference to FIG.
[0008]
FIG. When the cutter is moved to the middle of the drawer, the rigidity of the adhesive tape itself is applied, and the outer periphery of the adhesive portion 6 (rotator 6a) adhered to the adhesive tape is pressed, so that the adhesive portion 6 (rotator 6a) rotates. Therefore, the end of the adhesive tape on the side of the cutter 4 is curved so that the adhesive surface is on the inside.
[0009]
FIG. An example in which the adhesive part in the middle of drawing is a rotator. As the cutter approaches, the rotator rotates due to the rigidity of the tape and induces rounding of the tape. Since the portion close to the winding portion of the tape has a tendency to curve downward as shown in the figure, it also induces bending as shown in the figure.
[0010]
FIG. The start of the operation of FIG. 1 in which FIG. 2 and FIG. 3 are combined.
When the tape is compressed by moving the cutter, the middle of the tape rises greatly.
FIG. Further, when the cutter 4 is pressed, the curve becomes stronger, and the shape is made such that the adhesive tape is stuck together with the finger and the adhesive tape 2 is easily pulled out. After this, the shape is as shown in FIG.
[0011]
【Example】
Figure 1 shows the basic form. FIGS. 6 and 7.8.9 show examples of auxiliary mechanisms that may be added to FIG. 1 when they are implemented.
FIG. An example in which the pressing guide according to claim 2 is provided. At the time of cutting, the tape, which was in the state of the dotted line, is cut and loosened, and then has a slight bend as shown in the figure due to the pressing of the guide.
[0012]
FIG. Claims 3 and 4. An example in which the rotating device on the cutting device side is turned in conjunction with the movement of the cutting device. The pulley belt system uses the rotator as a pulley.
When a part of the belt 11 was hung on the intermediate bonding portion 5 (rotator 5a) and the bonding portion 6 (rotator 6a), and further hung on a spring 12 below, the adhesive tape 2 was cut while being pulled by the cutter 4. At the time, the entire belt 11 is stretched, but when the cutter 4 is peeled off and moved to the position side, the upper part of the belt 11 is loosened and pulled by other parts, so that the rotator 6a (adhesive part 6) which is also a pulley rotates. Acts to bend the adhesive tape upward.
[0013]
FIG. 4. The example 2 of claim 3.
When the cam is pulled down by a spring and presses against the intermediate bonding portion 5 (rotator 5a) and the bonding portion 6 (rotator 6a) which also serves as a pulley, and the cutting device 4 moves in the direction of the arrow, both rotators are rotated by the cam. Works to bend the adhesive tape upward.
FIG. 3. Example 3 of claim 3.
The pulley 21 connected to the rotator 6a (adhesive portion 6) is inserted into the short elongated hole 18 of the cam 17, is inserted into the support 20 fixed to the installation table 1 in the partially inclined elongated hole 19, and the cutter 4 is removed. When moved to the side, the support 20 stops at the inclined portion of the long hole 19, and the short long hole is in contact with the rotator 6a from above, so that the pulley 21 rotates by the amount of movement in the long hole 18, and The adhesive tape in contact with the rotator 6a is bent upward, and then the support 20 moves in the elongated hole by the movement of the rotator 6a, and the adhesive tape is further bent as shown in FIG.
[0014]
【The invention's effect】
When pinching with a finger to use the tape, it is possible to fold the tape end just by pinching without fail.
