摘要

Improvements in machine to make the vacuum and automatically weld with simultaneous hermetic sealing bags of thermoplastic materialscharacterized because it has a delivery system consisting of a hollow chamber that communicates on the bottom with the vacuum regulator tank through the solenoid valves and goes joined to the table by its sides of greater diametromediante other membranes while it is loose by the shorter sides; in the upper part of the hollow chamber there is a sheet with one or more holes which supports an elastic rubber gasket on which rests a moving metal part with a longitudinal groove that carries a hardened rubber and is provided with terminals where it connects a resistance d sheets with protective fabric to constitute the clamp of the drive mechanism.
