来る。According to the present invention, since the cutting portion of the band-shaped member is shaped by the heated pressing die, the thickness of the cutting portion is reduced and the cutting is performed by the cutting blade, even the wide band-shaped member is formed. The problem that the central portion and the like are not sufficiently cut does not occur. Further, even when cutting an adhesive band-shaped member, for example, an unvulcanized rubber sheet, the pressure applied to the pressing die can be made smaller than before, so that the unvulcanized heated die is not vulcanized. It is possible to prevent the crushed rubber from adhering to the rubber sheet in a powder form on the surface in contact with the rubber sheet, and to suppress the adhesion of the cut rubber sheet to the pressing die, enabling continuous and efficient cutting work. .

The cut portion S1 of the belt-shaped member S is modeled with a, and the cut portion S
Since the thickness of 1 is cut by the cutting blade 11 after the thickness is reduced, there is no problem that the central portion or the like of the wide band-shaped member is not sufficiently cut, and it is possible to cut reliably and easily. Since the imprinting and the cutting are separated, it is not necessary to press the heated pressing die 5a with high pressure, the cutting device D is small, and the tip of the pressing die 5a is less worn, and the life of the pressing die 5a is kept long. Can be done.

As a result, the cutting portion S1 can be appropriately shaped and cut. The cutting blade 11 is not limited to a round blade shape that is rotatably supported. For example, a plate-shaped knife or the like can be run without rotating, and the cutting means 9 or a guillotine-type cutter or the like can be used. The belt-shaped member S may be dropped at the cutting portion S1 to be cut once. Further, since the cutting portion S1 of the belt-shaped member S is easily cut with a smaller load, it is possible to heat the cutting blade 11.
