The production (of these types) of artifacts made of synthetic material can be set-up adopting a "continuous" system process organization. The synthetic material is supplied in rolls or spool usually up to 1400mm wide that can be cut with appropriate equipment, named “slitting” into several parts and spooled. Starting from material in coils in the two types provided, one for the right of the article and the other for the lining, you can arrange an island work for the obtaining of belts, straps and the like.
