Abstract
A molding method for a seamless crawler is provided in which the number of production steps is few, embedding of spiral reinforcement cords and a circumferentially uniform strength property are made possible, high-speed traveling can be accommodated, and a uniform, reliable pressure for an outer mold is enabled. The crawler molding method is structured such that a crawler is integrally molded and vulcanized between an endless ring-shaped outer mold and an inner mold . After structural components of the crawler are molded at an outer periphery of the inner mold which is dividable in an axial direction, the outer mold which is divided in a circumferential direction and is slidable in a radial direction is disposed at an outer side an the structural components of the crawler . The outer mold is contracted in the radial direction by pressure applied thereto. Accordingly, the structural components of the crawler are vulcanized.
