Abstract

A universal unit esp. suitable welding machines producing articles from PVC sheet, such as filing cases, envelopes, etc., delivers the welded prods. on to a conveyor for stacking, boxing, etc. It comprises two pairs of draw rollers with a conveyor belt between them, and adjustable in the horizontal direction relatively to each other. The pressure exerted by each pair of rollers is also adjustable. After welding, the prod. is cooled, a stamping operation may be effected on itm and as it travels with the belt it may be released by a jet of air. The unit fits in behind a HF welding machine to make the operation fully automatic. The machine works by tension, clamping the band of material at each stroke and drawing the welded prod. free.
