Abstract

PURPOSE: To allow a tape to be cut while the edges of the mating end parts are formed in taper shape by providing a fixed member for supporting either one of a lower blade member and an upper blade member, and a movable member for moving the other member vertically. CONSTITUTION: With the movement of a movable member 16, the respective cutting edges 171 of a pair of upper blade members 17 come in contact with both ends of a tape on a lower blade member 13 from the lower side end parts so as to press and bend the tape in inverted V-shape along the down-inclined faces 132 on both sides of the cutting edge of the lower blade member 13. The respective cutting edges 171 cut into the tape from both sides obliquely along the wedge shape on the tip part 133 side of the lower blade member 13 and cut into both sides of the downward inclined tape vertically downward along both vertical planes on the tip side of the lower blade member 13. With this operation, the tape is cut into such shape that the tip part is of wedge shape of 90 deg. and that both side edges to be the cut faces are inclined downward to the side.

The first type is a method of directly attaching to the lower mold, where the upper mold streaks are transferred to the lower mold in advance using carbon paper, and the tape is taped to a predetermined size according to each streaks, In addition, the end portion of the tape to be joined is cut into a 90 ° square wedge shape. Then, the release paper on the back surface is peeled off, and the groove at the center of the tape is attached through the transparent film while aligning with the stripes. Further, the cut surfaces of the mating portions of the respective tapes are brought into contact with each other.

In this case, a tape having an auxiliary member on the surface is used. The auxiliary member has a groove on the front surface into which a blade for forming an upper die can be fitted, and has a protrusion on the back surface that can be fitted into the groove on the tape surface, and is entirely ribbon-shaped. It is attached to the surface of the tape. The tape is cut into a predetermined size with a tape cutter for each blade for forming the folds of the upper die, and the end portion that is the mating portion is cut into a wedge shape of 90 ° angle, and the tape is cut using the groove on the surface of the auxiliary member. It is attached to the blade for forming the upper fold line. After the tape is mounted at the required location, the release paper is removed from the back surface of each tape, and the punching machine is pressed once to attach the tape to the lower mold via the adhesive layer on the back surface.

なく、実効ある問題解決にまで至っていない。As described above, in the conventional punching of thick paper of this kind, the crease forming tape to be adhered to the lower mold is made to have a predetermined length, and the end portion to be the mating portion is formed. It is cut into a 90 ° square wedge shape, and a tape cutter is used for the cutting. However, in the above-mentioned conventional tape cutter, the tape is cut vertically from the surface by pressing and cutting, so that the mating end portion becomes a vertical cutting surface, and when the mating end portions are combined, the entire cutting surface is in contact. Due to the continuous use of the lower mold for contacting, there is a problem that the cut surfaces at the mating end portions of the tape are pressed against each other by the repeated pressing of the tape surface against the press board, and are gradually separated. In order to deal with this, in the past, the edges of the mating end were cut diagonally by hand to form a tapered shape so that the cut surfaces do not hit each other, but the cutting work is easy. Moreover, effective problem solving has not been reached.

First, the tape is fed along the groove on the surface center along the cutting edge of the lower blade member. By moving either the upper blade member or the lower blade member vertically with respect to the other by moving the movable member in the vertical direction, the cutting edge of the upper blade member moves downward from its lower end. It hits both sides of the tape on the blade member and is pressed to bend the tape in an inverted V shape along the downward inclined surfaces on both sides of the cutting blade of the lower blade member. When the lower end of the cutting blade reaches both vertical planes of the tip of the lower blade member, the tape is inclined from both sides of the tape along the wedge shape of the tip portion of the lower blade member, and is inclined downward. Cut vertically on both sides of the surface along both vertical planes of the lower blade member end. As a result, the tip portion of the tape is, for example, 90
It is wedge-shaped with an angle of ∘, and both side edges thereof are cut on a taper inclined downward in the lateral direction.

The tape is pressed against both sides of the upper tape, and the tape is bent in an inverted V shape along the downward inclined surfaces on both sides of the cutting blade of the lower blade member 13. When the tape is completely folded and the lower end of each cutting edge 171 reaches both vertical planes 134 of the tip of the lower blade member 13, each cutting edge 171 moves the tape from both sides to the lower blade. The member 13 is cut diagonally along the wedge shape on the side of the tip 133 of the member 13, and is vertically cut along both vertical planes 134 on the tip side of the lower blade member 13 with respect to both sides of the tape surface that is inclined downward. as a result,
The tape is cut along the shape of the vertical flat surface 134 at the tip of the lower blade member 13 while cutting the corners on the surface side of the cutting surface. By this operation, the tip portion of the tape is cut into a wedge shape with a 90 ° angle, and both side edges, which are cut surfaces thereof, are tapered so as to be inclined downward in the lateral direction.

The lower blade member 13 having the inclined surface 132 formed on the upper surface and the vertical flat surface 134 which has a wedge shape in its front end side and is joined to both sides thereof at an opening angle of 60 °.
And is attached to the base member 11 via the movable member 16, and the cutting blades 171 are formed in a V shape in the vertical direction along each vertical plane 134 of the lower blade member 13 from the narrow side to the wide side. Upper blade member 1 arranged to be gradually inclined downward
7 and the tape is bent in an inverted V shape and cut into a wedge shape from the vertical direction, the tape can be formed into a wedge shape and, at the same time, its side edges can be cut into a taper shape. In this embodiment, the movable member 16 is driven by an electric drive means to vertically move the upper blade member 161 with respect to the lower blade member 13, so that the tape is used as the lower blade member 13. The work can be carried out very simply by feeding it into the upper blade member 16 according to the set dimension and operating the operation button.

A base member and a vertical surface which is arranged on the base member and has an inverted V-shaped cross-section at the upper part, inclined surfaces formed on both sides of the top, and a wedge-shaped plane shape, and is joined to both sides at an angle of 60 °. On the lower blade member having a flat surface, and the base member, a cutting blade is formed in the vertical direction along each vertical plane of the lower blade member.
An upper blade member arranged in a letter shape and gradually inclined downward from a narrower side to a wider side, and a fixing member supporting one of the lower blade member and the upper blade member and the other vertically. Since the tape is bent in an inverted V shape and cut in a wedge shape from the vertical direction, the tape can be cut while the edges of its mating ends are tapered. By using this tape cutter, workability in cutting the tape can be significantly improved.
