STITCHING DEVICE AND STITCHING METHOD

摘要

An object of the disclosure is to provide a stitching device and a stitching method enabling a stitching jig to be orthogonally pressed against a predetermined surface portion of a tire intermediate member or assembly. The stitching device is characteristically structured such that a fulcrum portion is movable in the tire width direction of the tire intermediate member and/or the fulcrum portion and the stitching portion are positioned on one side and the other side with respect to the tire equatorial plane of the tire intermediate member, respectively. The stitching method characteristically includes moving the fulcrum portion in the tire width direction of the tire intermediate member in the stitching operation and/or positioning the fulcrum portion and the stitching portion to be on one side and the other side with respect to the tire equatorial plane of the tire intermediate member, respectively, in the stitching operation.

主权项

1. A stitching device for pressure-attaching a tire structural member on a tire intermediate member, wherein the device comprises:
a support portion capable of moving in the tire radial direction of the tire intermediate member; a fulcrum portion provided in the support portion; an arm connected at one side thereof with the fulcrum portion to be pivotally movable around the fulcrum portion; and a stitching portion having a stitching jig and connected with the other side of the arm, wherein the fulcrum portion is adapted to be movable in the tire width direction of the tire intermediate member in a stitching operation.
