Abstract
Abstract An endless reinforcement comprising a unitary strip positioned across the width of the reinforcement from one side to the other at an angle to the edges of the reinforcement, the unitary strip including a multiplicity of continuous filaments surrounded and separated by rubber disposed in a contiguous undulating relationship throughout the length of the strip. Also, apparatus for forming a unitary strip including interdigitating gripper means arranged in an oval path, means for advancing the gripper means around the oval path, and means for increasing the degree of interdigitation of the gripper means during a portion of their advancement around the oval path.
