  The bonding means C is a means for bonding the pressure-sensitive adhesive surfaces 2 of the pressure-sensitive adhesive tape 2 with the side edges 2S folded back to each other, and is provided between the folding mechanism B and the cutting means 14. In the present embodiment, the bonding means C is composed of a rubber pressure roller 28. The pressing roller 28 contacts and presses the non-adhesive surface side of the adhesive tape 2 with the side edge 2S folded back, and presses and adheres the adhesive surface 2a of the adhesive tape 2 to the object to be applied. A part of the outer peripheral surface of the main body case 16 is slightly protruded and exposed to the outside from the outlet 18 of the main body case 16, and is provided on the side of the cutting means 14. The pressing roller 28 is attached to a pair of opposing side plate portions 17 of the main body case 16 so that both ends thereof are rotatably supported. A guide roller 32 for smoothly guiding the pressure-sensitive adhesive tape 2 to the pressure roller 28 while being in contact with the pressure-sensitive adhesive surface 2a side of the pressure-sensitive adhesive tape 2 is provided between the pressure roller 28 and the cutout block 26b.

It is pivotally supported. Then, the swing lever 14a is disposed in close proximity with the inner surface side bent in the shape of the U facing the pressing roller 28, and one end side to which the cutting blade 14b is attached swings in a direction away from the pressing roller 28. The other end side is close to the pressing roller 28, and the bent inner surface comes into contact with the outer peripheral surface of the pressing roller 28 to function as a brake mechanism that restricts the rotation of the pressing roller 28.

  Here, as shown in FIGS. 3 and 4, the main body case 16 is made of a pair of transparent plastics having a substantially symmetrical shape, with the central portion in the width direction of the adhesive tape 2 housed therein being a dividing line. The split cases 16a and 16b are configured to be separable in half. That is, the inner and outer diameters of the cylindrical support portions 12a and 12b protruding from the side plate portions 17a and 17b of the divided cases 16a and 16b are formed in different sizes so as to be detachable from each other. Are fitted and coupled. Moreover, the vertical walls 19a and 19b which form the surrounding wall 19 are integrally protrudingly formed in the peripheral edge of each side-plate part 17a and 17b, and the front-end | tips of the said vertical walls 19a and 19b are faced | matched. The inside of the cylindrical support portion 12 is formed so as to penetrate therethrough, whereby the support portion 12 is formed as a gripping portion 13 that can be gripped by an operator.

Next, sticking of the adhesive tape 2 performed using this tape cutter 10 will be described.
First, the main body case 16 is opened, and the adhesive tape wound body 4 is mounted and accommodated on the tape support 2. Then, from this state, the tip of the adhesive tape 2 is picked with a fingertip and pulled out from the adhesive tape wound body 4, and the pulled-out adhesive tape 2 is inserted and set between the members of the overlapping portion forming means 20, and the tip is removed. It guide | induces out of the main body case 16 from the drawer outlet 18, and the split cases 16a and 16b are fitted in this state, and the main body case 16 is closed.

And if the front-end | tip of the adhesive tape 2 is picked and it pulls out further from the adhesive tape winding body 4, a tension | tensile_strength will act on the said extracted part. At this time, the end 22a of the folding roller 22 is positioned on the adhesive surface 2a of the adhesive tape 2, and one side end in the longitudinal direction of the adhesive tape 2 is not in contact with the bending roller 22. Therefore, the adhesive tape 2 is a portion that hits the outer peripheral edge of the end portion 22a of the bending roller 22, and the side edge 2S is bent along the longitudinal direction with the adhesive surface 2a inside, It enters between the part 22a and the bending guide piece 24, and is in a state of being bent up to approximately 90 degrees at that portion.
The inclined surface 27 of the inclined block 26a is in contact with one side end of the adhesive tape 2, that is, the non-adhesive surface 2b at the side, and the one side end of the adhesive tape 2 has the adhesive surface 2a inside. It will be bent to a further acute angle.

  Further, in the cutout block 26b, the adhesive tape 2 is contacted in a state of being bent at an acute angle by the inclined block 26a, and the pressure-sensitive adhesive surfaces 2a facing each other are substantially increased while gradually increasing the degree of bending in the cutout portion 26c. It is bent until it becomes parallel. That is, a superposed portion with the adhesive surface 2a on the inside is continuously formed at one side end of the adhesive tape 2. Further, such a series of steps is continuously performed by sequentially pulling out the adhesive tape 2a from the adhesive tape wound body 4.

  Then, the adhesive tape 2a is pulled out and cut with the cutting blade 14b until the portion where the overlapping portion is cleanly formed reaches the cutting means 14, whereby the attachment of the adhesive tape winding body 4 to the tape cutter 10 is completed.

  Here, the dimension of the overlapping part formed by the folding mechanism part B is regulated to a predetermined dimension W by the folding roller 22. That is, as shown in FIG. 6, the adhesive tape 2 is not bent at the portion in contact with the outer peripheral surface 22 b of the bending roller 22, and the size of the overlapping portion is a non-contact protruding from the end 22 a of the bending roller 22 to the side. The side edge 2S of the portion is formed so as to be maintained at a predetermined width W.

  When sticking the adhesive tape 2 to an object such as an envelope, the gripping part 13 of the tape cutter 10 is held with one hand and the tip of the adhesive tape 2 is pressed against the object to be attached by the pressing roller 28. However, the tape cutter 10 is moved along the desired affixing line as shown in FIG. 7A, and the adhesive tape 2 is affixed while being pulled out from the wound body 4. At this time, the side surfaces 2S of the pressure-sensitive adhesive tape 2a folded back and the pressure-sensitive adhesive surfaces 2a facing each other are pressed against each other, and the side edge 2S is folded back to one side end or side of the pressure-sensitive adhesive surface 2a. The adhesive tape 2 is stuck to the object while the formed overlapping portion is reliably formed.

  Then, when the adhesive tape 2 is pulled out and pasted over an envelope or the like over a desired length, as shown in FIG. It will be cut by pressing against 2. At this time, when the cutting blade 14b is pressed against the adhesive tape 2, the swing lever 14a swings in a direction in which one end on the cutting blade 14b side is separated from the pressing roller, and the other end side is close to the pressing roller and bent. The inner surface thus brought into contact with the outer peripheral surface of the pressing roller functions as a brake mechanism by restricting the rotation of the pressing roller 28. The pressure-sensitive adhesive tape 2 is wound around the outer periphery of the pressure roller 28 over a substantially half circumference, and therefore, the tension of the pressure-sensitive adhesive tape 2 generated at the time of cutting can be received by the pressure roller 28, and the tension applied to the tape winding body 4 is increased. It is possible to prevent the adhesive tape 2 from being pulled out of the tape wound body 4 as much as possible. Therefore, even if it uses the adhesive tape 2 of the type by which the release agent is apply | coated or impregnated to the base material, it can cut | disconnect reliably in desired length and a position.

  Moreover, by using this tape cutter 10, while forming the superposition | polymerization part 50 which is a non-adhesion part on the one side edge of the adhesive surface 2a of the adhesive tape 2 easily and continuously along a longitudinal direction, the said adhesive tape 2a is made. As a result, the overlapping portion 50 can be used as a picking portion, and the overlapping portion can be easily picked and peeled off from the adhesive tape.

  The adhesive tape cutter 10 described above is exemplified by the tape wound body 4 and the superposed portion forming means 20 etc. that are completely housed and enclosed in the main body case 16. Is not limited to this. For example, as shown in Patent Document 1, a tape that covers at least a portion of an adhesive tape winding body supported by a support portion and forms a gripping portion in contact with the outer peripheral surface of the adhesive tape winding body The present invention can also be applied to an adhesive tape cutter for packing, in which a cover is rotatably provided on a main body bracket.
