Title:
RUBBER SHEET MEMBER JOINING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/239681
Kind Code:
A1
Abstract:
Provided are a rubber sheet member joining device and method with which end surfaces of unvulcanized rubber sheet members are positioned precisely and rapidly at predetermined positions so as to enable efficient joining. A contact member 5 is placed on at least one of opposing surfaces 3a, 4a of a pair of gripping parts 3, 4, and the contact member 5 has a contact surface 5a that protrudes toward the opposing surface of the other gripping part. An area near end surfaces 13a, 13b is gripped by the gripping parts 3, 4 in a state where the end surfaces 13a, 13b respectively protrude from the opposing surfaces 3a, 4a toward the other opposing surface. The sum of end surface protrusion amounts d1, d2, which are the amounts by which the end surfaces 13a, 13b protrude from the opposing surfaces 3a, 4a, are set to be greater by a prescribed length B than the distance L of separation between the opposing surfaces 3a, 4a when the contact member 5 is sandwiched and held between the opposing surfaces 3a, 4a. By sandwiching and holding the contact member 5 between the opposing surfaces 3a, 4a, the movement by which the gripping parts 3, 4 approach each other is stopped, and the end surfaces 13a, 13b are joined together.
