ル。[Scope of Claim for Utility Model Registration] (1) A heat roll 1 having a welding blade 2 around it and heated by a heater, and the welding blade 2
It is a heat-sealing roll equipped with a rotatable support roll 11 whose circumferential surface can be brought into contact with the cutting edge of the welding blade 2, and a pressing body 4 is provided along the cutting edge on both sides of the welding blade 2. The distance l between the lower end of the body 4 and the cutting edge of the welding blade 2 is such that the multilayer thermoplastic resin sheet A to be welded is lightly pressed, and the upper surface of the sheet A is pressed against the sheet A at the time of welding, and a predetermined pressure is applied to the sheet A. A welding heat seal roll that allows the addition of (2) The welding heat seal roll according to claim 1, wherein the receiving roll 11 has a peripheral surface 12 covered with a heat-resistant elastic material. (3) Claim 1 or 2, wherein the pressing body 4 is made of a heat-resistant elastic body, and can be applied to thermoplastic resin sheets A of various thicknesses due to its own elasticity.
Welding heat seal roll as described in section. (4) The welding heat seal roll according to any one of claims 1 to 3, further comprising a cooling means 5 for cooling the pressing body 4. (5) The welding heat seal roll according to any one of claims 1 to 4, wherein both a melt seal and a hot plate seal can be achieved by appropriately selecting the heating temperature and pressing pressure.
