<p><P>PROBLEM TO BE SOLVED: To provide a method for manufacturing an elastic crawler, in which the elastic crawler can be vulcanized and bonded strongly and to provide a vulcanizing/molding apparatus using the method. <P>SOLUTION: A band-shaped rubbery body 7 is vulcanized/molded in a metallic die 8, which is divided into a heating zone H and a cooling zone C in the longitudinal direction thereof, while keeping one end of the band-shaped rubbery body in the longitudinal direction thereof non-vulcanized or semi-vulcanized. The non-vulcanized or semi-vulcanized joint surface 14 of one end of the band-shaped rubbery body 7 is joined to the other non-vulcanized or semi-vulcanized end of the same band-shaped rubbery body 71 or another band-shaped rubbery body 72 in the longitudinal direction thereof and the joined part is vulcanized and bonded. A product is manufactured by integrating one end of a single or a plurality of band-shaped rubbery bodies 7 with the other end thereof into one body. The joint surface 14 is bonded to the other end of the band-shaped rubbery body 7 while being vulcanized in such a state that a boundary line B between the joint surface 14 of the band-shaped rubbery body 7 and the outside surface 2A of the product is located in a position that is within the cooling zone C and is parted from the heating zone H. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
