Embodiment Construction

[0043] In different figures, the same or similar parts bear the same reference signs. Therefore, descriptions of the structures and functions of these same or similar components are not systematically repeated.

[0044] pass figure 1 The basic principle of the method and device according to the invention can be seen.

[0045] The method of the invention is a substantially continuous method comprising firstly converting a straight reinforcing strip 20 into a corrugated strip 21 , which is then laid in corrugated form to the tire blank 50 . These two steps are carried out sequentially, preferably in succession. The corrugated strip is wound on the green tire step by step with multiple turns. The undulations and movement of the corrugated strips 21 towards the surface of the green tire extend in a plane perpendicular to the axis of the green tire, ie to the axis 32 of the building drum 3 supporting and controlling the rotation of the green tire 50 . It will be understood tha...

Abstract

The invention relates in particular to a method for the manufacture of tires, said method comprising in sequence the steps of successively transforming a flat reinforcing strip (20) into a corrugated reinforcing strip (21), pressing the crests (211) of the corrugated strip one by one onto the surface (501) of a tire blank (50) which is rotated by the building drum (3) about its axis (32) and the corrugated reinforcing strip is wound onto the tire blank , the straight reinforcing strip is transformed into a corrugated strip in the immediate vicinity of the building drum, the undulations of the corrugated strip and the movement of the crests towards the surface of the green tire lie in a plane substantially perpendicular to the axis of the building drum.

Description

technical field [0001] The invention relates to the field of manufacture of tires for passenger vehicles or utility vehicles, and more particularly to an assembly method for laying all the constituent parts of said tires continuously and substantially without changing the diameter of the lay. Background technique [0002] In these methods, all operations for assembling a green tire are carried out on a building drum, the diameter of which preferably corresponds substantially to the inner diameter of the tire (commonly referred to as the "rim seat diameter", which is the standard diameter of the rim on which it is mounted during use). Thus, not only the carcass, beads and sidewalls, but also the crown reinforcement and the tread can be laid on the assembled drum, the diameter of which substantially corresponds to the diameter of the rim well. One advantage of these types of methods is the ability to keep the green tire on the same building drum throughout the assembly proces...
