APPARATUS FOR MOUNTING TREAD RING ON TIRE BASE AND METHOD FOR MANUFACTURING RETREADED TIRE

摘要

An apparatus 1 for mounting an annular tread ring R on an outer peripheral surface TS of a tire base T, which includes a tire base holding section 2 which is movable between a first position P1 and a second position P2 while holding the tire base T, and a tread ring mounting section 3 for mounting the tread ring R on the outer peripheral surface TS of the tire base T. The tread ring mounting section 3 comprises a tread holder 10 for holding the inner circumferential surface of the tread ring R, and a tread pushing-out device 11 for pushing out the tread ring R in the axis direction. At the second position P2, after placing the tread ring R on the outer peripheral surface TS of the tire base T in the tire base holding section 2, the tread ring mounting section 3 pushes out the tread ring R from the tread holder 10 toward the first position P1 by the tread pushing-out device 11. And the tire base holding section 2 moves toward the first position P1 at the same speed as the pushing-out speed of the tread pushing-out device 11. Thereby, the tread ring R is mounted on the outer peripheral surface TS of the tire base T.

1. An apparatus for mounting an annular tread ring made of vulcanized rubber on an outer peripheral surface of a tire base, characterized by comprising
a tire base holding section for holding the tire base which is movable in an axis direction of the tire base between a first position and a second position, and a tread ring mounting section for mounting the tread ring on the outer peripheral surface of the tire base which is disposed on the second position side of the tire base holding section, the tread ring mounting section comprising a tread holder for holding the inner circumferential surface of the tread ring, and a tread pushing-out device for pushing out the tread ring held by the tread holder in the axis direction, wherein at the second position, after placing the tread ring on the outer peripheral surface of the tire base in the tire base holding section, the tread ring mounting section pushes out the tread ring from the tread holder toward the first position by the tread pushing-out device, and at the same speed as the pushed-out tread ring, the tire base holding section moves toward the first position, whereby the tread ring is mounted on the outer peripheral surface of the tire base.
