Method of joining the ends of lengths of material

摘要

In a process for joining the ends of rubber or elastomeric strip (1) having a thin cross-section, esp. thin edges (3) the strip ends (1) are cut to an angled profile and immediately before joining together are prestretched to a given amount in the thinner areas. Process equipment is also claimed including elements (5) for gripping the front end of a material strip (1) at points across the width. Those gripping the material in the thinner areas have controlled movement in the strip (1) direction.
