Apparatus and a method for manufacturing rubber crawler of rubber crawler

摘要

PROBLEM TO BE SOLVED: To prevent fall of a preform arranged at a housing recessed part of a mold outer peripheral surface when a rubber crawler is manufactured.;SOLUTION: A plurality of housing recessed parts 15 are formed at fixed intervals in a peripheral direction on the outer peripheral surface of the drum-shaped mold 11. After the preforms for forming a driving protrusion are respectively arranged at these housing recessed parts 15, a rubber sheet member is wound up over a whole outer peripheral surface of the mold 11, then the rubber sheet member is pressurized over its whole periphery from the outside in a radial direction and the rubber sheet member and the preform are vulcanized by heating them in a state where an inner peripheral surface of the rubber sheet member is brought into close contact with the preform to form the rubber crawler. In this manufacturing apparatus 10 of the rubber crawler, a fall prevention section of the preform is provided at the housing recessed part 15.;COPYRIGHT: (C)2009,JPO&INPIT
