METHOD AND APPARATUS FOR PRESS-BONDING TIRE COMPONENT MEMBER, TIRE MOLDING APPARATUS

摘要

PROBLEM TO BE SOLVED: To stably obtain enough press-bonding force and to make the press-bonding force of a joint uniform when the joint of a tire component member wound onto a molding drum is press-bonded.;SOLUTION: An apparatus 1 for press-bonding the joint 31 of the tire component member 30 is equipped with a press roller 10 being rotatable around the axis and having a core member 12 made of an elastomer such as rubber and a plurality of annular disks 13 which are laid in the axial direction to overlap each other and arranged around the core member 12. The press roller 10 is pushed against the joint 31, each annular disk 13 is displaced in the radial direction to correspond to the unevenness etc., of a pushing position by the elastic deformation of the core member 12, and the press surface of the press roller 10 is made to follow the shape of the joint 31 and deformed. The press roller 10 is made to tumble along the joint 31, its press surface is deformed in accordance with the shape of the joint 31, and the whole joint 31 is pressed and press-bonded.;COPYRIGHT: (C)2008,JPO&INPIT
