Next, how to use it will be explained.

The spacer 3 is set in the clamping frame 1A of the punching blade die 1 so as to extend in both width directions of the label to be cut, while the spacer 4 is set in the clamping frame 1B so as to extend in the label feeding direction. do. That is, openings 9,
10, spacers 3 and 4 are inserted in the cutting direction of the label, respectively. In this way, multiple spacers 3,
4 into the recesses 5 and 6, and finally the presser pieces 13 and 14 are inserted. With the spacers 3 and 4 and the holding pieces 13 and 14 inserted in this manner, the tightening bolts 1 are attached to the tightening frames 1A and 1B.
By screwing bolts 5 and 17 together in the tightening direction, a state is obtained in which the tips of the tightening bolts 15 and 17 abut against the holding pieces 13 and 14, respectively. Further, through the screwing action of the tightening bolts 15, 17, a state in which the spacers 3, 4 are arranged in layers in the recesses 5, 6 can be obtained. In this state that the spacers 3 and 4 are arranged in layers in the recesses 5 and 6, one
By fitting the second punching blades 11 and 12, respectively, a state is obtained in which the punching blades 11 and 12 extend in the cutting direction. In addition, with the first punching blades 11 and 12 set in this manner, the second punching blades 11 and 12 are inserted into the spacer 3 and the second punching blades 11 and 12 with an appropriate distance between them. 3 and between the spacers 4 and 4, the double punching blade 1
1, 11 and 12, 12 extend parallel to each other in the cutting direction of the label with spacers 3 and 4 interposed therebetween. By interposing an appropriate number of spacers 3, 4 between the punching blades 11, 11 and 12, 12 in this manner, the distance between them can be adjusted. Then, with the spacing between the punching blades 11, 11 and 12, 12 adjusted, the tightening bolts 15, 17 are screwed together in the tightening direction, so that the tips of the tightening bolts 15, 17 are attached to the presser piece 13. , 14 is gradually pressed. Tighten the holding pieces 13 and 14 in this way and bolt 1.
5 and 17, the spacers 3 and 4 are pressed by the tightening bolts 15 and 17 via the holding pieces 13 and 14. In this way, the spacer 3,
By pressing 4, the punching blades 11 and 12 can be crimped between the spacers 3, 3 and between the spacers 4, 4, respectively. After the punching blades 11 and 12 are set in the punching die 1 in this way, the punching die 1 is attached to the ram of the press by an excitation action in alignment with the cutting direction. An endless sheet of tack paper is set on the press table. With the cutting blade die 1 and the tack paper set in this manner, the ram of the press is reciprocated toward the tack paper in conjunction with the intermittent feeding of the tack paper, so that the cutter die 1 is removed from the tack paper. A state for cutting paper labels is obtained. More specifically, the cutting blade 11 set in the clamping frame 1A cuts the label printed with a sticker on the label paper along both width directions, while the cutting blade 12 set in the clamping frame 1B cuts the label. The portion along the feeding direction of the label is cut at different positions, separately from the cutting in both width directions of the label. Then, in the next step, the label paper is intermittently fed, so that a state is obtained in which the punching blade 11 faces the label that has already been cut in the feeding direction by the punching blade 12 in the previous step. Also, in this state, by sliding the ram of the press in the punching direction,
The label is cut in both width directions by the punching blade 11, thereby cutting the label over its entire circumference. That is, label cutting is performed in two steps in this way. After sequential cutting is performed in this manner, the tack paper is separated into a backing paper to which a label piece is attached and a cut-out portion thereof, and the cut-out portion is wound up into a roll.

In this embodiment, two punching blades 11 and 12 are pressed onto the clamping frames 1A and 1B, but the number is not limited to two, and any number of punching blades may be used. Further, by crimping a plurality of punching blades in parallel in a staggered manner, it is also possible to cut the label in a stepwise manner. Multiple punching blades are not set only in the label feeding direction and both width directions; for example, by crimping the punching blades against the clamping frame and then attaching them diagonally to the ram of the press. , the label cutting direction can be freely set. Furthermore, the clamping frame is not limited to being an integral part as in this embodiment, but can also be provided separately. That is, in addition to being able to attach separately formed clamping frames to the same ram, they can also be attached separately to a plurality of presses. By attaching the clamping frame to multiple presses in this way at an appropriate angle of inclination, it is possible to cut complex shapes formed only by line segments, such as hexagons. becomes. Further, the spacers 3 and 4 are not limited to the same thickness dimension, but by using spacers gauged to various thickness dimensions, the spacing can be adjusted more accurately. Furthermore, the above-mentioned crimping means is not limited to the tightening bolts 15, 17, but may be, for example, springs or the like.

The present invention is constructed as described above.
As described above, a plurality of clamping frames formed in a substantially rectangular frame shape are provided, and each clamping frame has a plurality of punching blades extending parallel to the cutting direction of the label, the number of which is formed into a long strip shape. By interposing two spacers and crimping them so that the space between them can be freely adjusted, it has become possible to extremely easily set the punching blade to the punching blade die.

In addition, in the present invention, the plurality of punching blades arranged in parallel as described above are provided with an appropriate number of spacers formed in a long strip shape so that the distance between them can be adjusted freely. The interval between the punching blades can be freely set according to the size of the label, making it possible to obtain a versatile punching blade mold.

Furthermore, in the present invention, as described above, a plurality of clamping frames are attached to the press machine at different angles so that the cutting lines of the punching blades are square or polygonal. By combining the clamping frames, it has become possible to cut labels with complex shapes consisting only of line segments.
