VORRICHTUNG ZUM VARIIEREN DES ABSTANDES ZWISCHEN DEM SCHWEISSELEMENT UND DEM GEGEN-SCHWEISSELEMENT IN VERPACKUNGSMASCHINEN.

摘要

In machines for the continuous packaging of products inside a film of a plastic material, folded above said products, so as to form a continuous tubular wrapping, a device for changing the opening between the welding (12) element and the counter-welding element (13) makes it possible the operating distance between said elements (14, 13) to be changed as a function of the height of the products in course of packaging, thus ensuring the highest packaging speed for both low- and high-thickness products.
