The S411 machine was designed and built by studying directly “in the field”, the needs of the most experienced manufacturers of pvc covers. Solving the slow and laborious manual processes has always been a firm point of Alfredo Coli who, with satisfaction, offers the fully automatic and minimum-sized machine for welding PVC fabrics. Our innovative patented transport system TVP® guarantees superior quality welds on all types of plastic fabric and in any processing phase. Completely electro-pneumatic and very simple to use, the S411 reduces production times, making life easy even for the less experienced.
