ABSTRACT:
A strip of resilient material is clamped uniformly across the width of the material at a first position by vertically spaced clamps which are separated to stretch a section of the material beyond the elastic limit. The stretched section of material is released and transported on a horizontal conveyor to a second position where the stretched section is cut by a cutter providing edges of reduced thickness which are suitable for overlapping other stretched edges of reduced thickness for splicing.
