INRICHTING VOOR HET VORMEN VAN EEN CONTINUE STROOK UIT KORTE STUKKEN MATERIAAL.

摘要

A process and apparatus are provided for joining overlapping fore and rear ends of two pieces of deformable material which are placed in overlapping relationship through the conjunctive use of a first fixed support surface supporting a protruding rear edge of one of the pieces of material and a second rotative support surface supporting a non-protruding fore edge of the second piece of material. Each support surface is provided with associated devices for shifting an associated support edge of material to create small waves of material near the edges of the first and second pieces of material. The shifted pieces of material are overlapped by rotating the second support surface into substantial alignment with the first support surface thereby bringing the fore edge of the second piece under and in contact with the rear protruding edge of the first piece. A pressing device joins the overlapped edges of the two pieces of material by pressing them against the second support surface.
