Embodiment Construction

[0045] exist figure 1 and figure 2 shows a green tire ply turn-up device 2 according to the invention. The device 2 is used to realize the ply turn-up of the green tire blank 3, the tire is provided with a crown 4 and two sidewalls 5, the general shape of the crown 4 is close to cylindrical, and the sidewalls 5 are located on the tire The crown 4 extends oppositely on both sides and from the crown 5 along the main axis of the green tire 3 . The device 2 is capable of ply turning up any type of tire.

[0046] The device 2 comprises a base 6 for receiving a green tyre. The receiving base 6 comprises a shaft 7 , here substantially cylindrical in shape, with a main axis 8 . The shaft column 7 is mounted rotatably about an axis 8 relative to a frame 10 of the device 2 . The shaft column 7 has a bearing 12 on the outer surface, said bearing 12 is in figure 1 is shown schematically in , and serves to receive the green tire 3 for its ply turnup. The receiving base 6 is part of...

Abstract

The invention relates to methods for controlling a tyre blank turn-up method, in which the longitudinal and radial movements of turn-up arms (20) are controlled, independently of one another, relativeto a main axis (8) of the blank (3) in order to apply a gum element on at least one sidewall (5) of the blank (3). The radial movement of the arms is controlled using a speed set-value.

Description

technical field [0001] The present invention relates to ply turnup of a green tire for a tire. [0002] The manufacture of a green tire for a tire includes a ply turn-up step involving the application of a layer of raw rubber on the sidewalls of the green tire carcass. The objective of this step is on the one hand to fix the plies of raw rubber on each sidewall of the carcass green and on the other hand to bind the bead wires, which serve to improve the mechanical properties of the tyre. Background technique [0003] A device is known comprising a shaft, a support mounted to slide relative to the shaft, an arm hinged to the support, and a guide mechanism fixed to the shaft Post to guide the free end of the arm. [0004] Such a device works as follows. Install the green tire of the carcass on the axle post. The rubber layer is initially arranged cylindrically and covers the arms applied along the shaft column and parallel to each other. A drive mechanism slides the suppo...
