Abstract

The invention provides a seam allowance structure, a tire and a fitting method. The seam allowance structure is used for being arranged between a tire side and a lining layer of the tire, the seam allowance structure comprises a first fitting part, a second fitting part and a third fitting part, and the first fitting part is fitted with the tire side; the second fitting part is connected with the first fitting part; the second fitting part comprises a second fitting face used for being attached to the lining layer, the second fitting part is provided with a first pressing face and a second pressing face which are opposite to the second attaching face, and the second pressing face is arranged at the end, away from the first attaching part, of the first pressing face. The seam allowance structure provided by the invention solves the problem that the edge of the seam allowance is easy to warp when the tire is manufactured in the prior art.

Description

technical field [0001] The invention relates to the field of tire manufacturing, in particular to a sprue structure, a tire and a bonding method. Background technique [0002] The normal one-time production process of tires is as follows (taking four-drum molding machine as an example): [0003] 1) Fit drum: [0004] Position the light mark within the width a from the center, and carry out sidewall lamination; [0005] Use the width b from the center as the inner positioning light to carry out the lamination of the molded plastic parts 4; [0006] Attach the inner lining layer with the light mark at a distance of c from the center as the outer positioning; [0007] Attach the carcass with the light mark at the width c from the center as the outer positioning; [0008] Carcass rolling after compounding the above components; [0009] Use the light mark with the width f from the center as the inner positioning to perform bead walking. [0010] 2) Auxiliary drum: Carry out...
