HEAT SEALING MACHINE AND PROCESS FOR HEATING PLASTIC FILM EDGES |
摘要 |
A heat sealing machine for sealing polyester sheets is disclosed wherein edges of two polyester sheets are heat sealed together by being exposed to a nickel-chrome heating ribbon. The machine includes movable clamping bars for clamping polyester sheets to a work surface in a position to be heat sealed, and also includes a movable shield for shielding the freshly sealed plastic sheet from a heating element, as well as for providing an alignment guide for the next plastic sheet to be heat sealed on the machine, which cooperates with the clamping bar. |
