ASSEMBLING RADIAL TYRE SINGLE PIECE CARCASS BODY PLY AND SINGLE PIECE INNER LINER ON BUILDING DRUM

摘要

A method for manufacturing a first stage radial tire consisting of two superimposed tubular layers, of which the first, composed solely of elastomeric materials, is formed from a central innerliner, two lateral abrasion strips and two sidewalls, and the second consists of a body ply formed from a textile layer coated on both sides with elastomeric material and obtained by means of parallel textile cords lying in radial planes of the tire, the method providing for obtaining the body ply from a textile strip equal in width to the circumferential development of a tire building drum, and the cords of which strip constitute an axial warp, and for transversely cutting the aforementioned textile strip, after first coating it on both sides with elastomeric material, into portions equal in length to the axial development of the first stage tire.
