The width of plastic sheets is limited, using a calender, to 3 m. max. producing and cutting open a tube it is 16 m max. for polyethylene and 4 m max. for PVC sheets. Welding is used to obtain sheets of greater width. In the presently used method, sheets are laid down side by side with the necessary overlap for welding. The welding machine is as wide as the resulting sheet. It is proposed that the strips to be joined are placed one above the other in parallel planes and the welding is carried out in the vertical plane, requiring space and labour.(0/0)
