A pressing body 3 is provided on at least one side of the blade along the cutting edge, and the distance l between the lower end of the pressing body 3 and the cutting edge is such that it can lightly press the multi-layered thermoplastic resin sheet to be cut by melting. 1. A seal blade for fusing, characterized in that the gap is such that it can press against the upper surface of the sheet and apply a predetermined pressure to the sheet during fusing. (2) The seal blade for fusing according to claim 1, wherein pressing bodies are provided on both sides. (3) The sealing blade for fusing according to claim 1, wherein the pressing body 3 is a heat-resistant elastic body and can be used with thermoplastic resin sheets of various thicknesses due to its own elasticity. (4) The melt cutting device according to claim 1, wherein the pressing body 3 is made of a heat-resistant member, is provided so as to be movable toward the cutting edge, and is biased toward the cutting edge by the urging means 4. Seal blade. (5) A sealing blade for fusing according to any one of claims 1 to 4, further comprising a cooling means 5 for cooling the pressing body 3. (6) Claims 1 to 3, wherein the pressing body 3 is provided so as to be movable forward and backward toward the cutting edge, and can be fixed at a predetermined position.
The seal blade for fusing described in 4. (7) A sealing device using the sealing blade according to any one of claims 1 to 6, wherein the sealing blade temperature during sealing is set lower than the sealing blade temperature during fusing sealing, and the pedestal 21 supports the thermoplastic resin sheet. The temperature of the sealing blade (lower blade) is set higher than the temperature of the pedestal 21 (lower blade) at the time of sealing, and the pressure of the sealing blade at the time of sealing is set to a pressure that does not melt the thermoplastic resin sheet. A sealing device characterized by:
