That is, when the upper die is near the top dead center, and when the raw sheet for cutter is fed by a predetermined size between the punch of the upper die and the punch receiving hole of the lower blade, the raw sheet for peeling tape is removed. When supplied in a state of being superimposed on the lower surface,
When the upper die is lowered, the caulking foot is formed at the caulking foot forming portion, because the punch penetrates both the web sheet for the cutter and the web sheet for the peeling tape in contact with the lower surface thereof, At this time, the peeling tape sheet is tightly fixed to the lower surface of the cutter sheet via the caulking feet. After the above state, the upper die once rises, then, after the cutter raw sheet is sent out by one step by a predetermined dimension, when the upper die is lowered again, Since the raw sheet for cutter is sent out together with the raw sheet for peeling tape adhered to the lower surface thereof, the leading end portion of the raw sheet for cutter is held on the lower surface of the peeling tape. Along with the material sheet, the cutter is cut by the upper blade and the lower blade, and the cutter formed by this cutting is held down by the lower surface of the upper blade while the peeling tape generated by the simultaneous cutting is attached to the lower surface thereof. Then, it is caulked via the caulking foot to a predetermined position on the upper surface of the carton blank set on the upper surface of the lower mold.

Therefore, between the cutter caulked to the carton blank and the carton blank,
The part of the original sheet for peeling tape (peeling tape) connected to the lower surface of the cutter via caulking feet,
The raw material sheet for the peeling tape is partly protruded to the outside of the raw material sheet for the cutter in the width direction. When the anti-sheet is supplied to the cutter mounting device of the present invention, the peeling tape fixed to the carton blank as described above is
The end part protrudes from the end of the cutter, that is, it becomes a knob when peeling off the cutter,
It will be exposed outside the cutter.

The cutter mounting device according to another embodiment of the present invention has the above-described configuration, and operates as follows. That is, when the lower die is near the bottom dead center, when feeding the cutter raw sheet by a predetermined size between the punch of the lower die and the punch receiving hole of the upper blade, the raw sheet for the peeling tape is removed. When the lower die is raised, the punch penetrates both the original sheet for cutter and the original sheet for peeling tape in contact with the upper surface of the caulking foot forming portion when the lower die is raised and supplied in a state of being superimposed on the upper surface. At this time, the caulking foot is formed, and at this time, the peeling tape raw sheet is tightly fixed to the upper surface of the cutter raw sheet via the caulking foot. After the above state, the lower mold descends once, and then, after the cutter raw sheet is sent out by one step by the predetermined dimension,
Again, when the lower die is raised, the raw sheet for the cutter is sent out together with the raw sheet for the peeling tape adhered to the upper surface of the lower die. The sheet was cut by the lower blade and the upper blade together with the raw sheet for the peeling tape held on the upper surface, and the cutter generated by this cutting attached the peeling tape generated by the simultaneous cutting to the upper surface. As it is, it is held by the upper surface of the lower blade, rises, and is caulked through the caulking foot to a predetermined position on the lower surface of the carton blank set on the lower surface of the upper die.

Accordingly, in the case of the cutter mounting apparatus of this embodiment, the peeling which is connected to the upper surface of the cutter via a caulking foot is provided between the cutter caulked to the carton blank and the carton blank. A portion of the raw tape sheet (peeling tape) is directly sandwiched and caulked, and a part of the raw tape sheet is placed outside the raw cutter sheet in the width direction. When the raw sheet for the peeling tape is supplied to the cutter mounting device of the present invention in a state where the peeling tape is protruded, the peeling tape fixed to the carton blank as described above has an end portion thereof. It becomes protruding from the end of the cutter, that is,
It becomes a knob portion when the cutter is peeled off, and is exposed outside the cutter.
