Abstract

The tool which contains:
a support, and an arm bearing a strip extrusion member and a strip applicator roller, wherein the arm is articulated with respect to the support about a first axis parallel to a geometric axis of the roller and about a second axis tangential to a circumference of the roller, of the first and second axes at least one passing through a centre of gravity of the arm.

First claim

The invention claimed is:

1. Tool for laying a strip for producing a green tire blank comprising:
a support,
an arm bearing a strip extrusion member and a strip applicator roller, the arm being articulated with respect to the support about a first axis parallel to a rotational axis of the roller and about a second axis tangential to a circumference of the roller, the first and second axes passing through a center of gravity (G) of the arm, and
a cradle, the cradle having a half-cylinder shape with its cross-section in the form of an arc of a circle, open at a top of the circle, with the opening forming a cavity, and the cradle bearing the arm via the cavity such that pivoting of the arm about the second axis occurs relative to the cradle and is guided by an arc-shaped rack borne by the cradle.

2. Tool according to claim 1 , which comprises a bracket, the arm being articulated to the bracket about the first axis, the bracket being articulated to the support about the second axis .

3. Tool according to claim 1 , wherein the arm is articulated to the cradle about the first and second axes and the cradle is mounted such that it can slide with respect to the support in
a direction parallel to the axis of the roller, and
two directions perpendicular to one another and the direction parallel to the axis of the roller.

4. Tool according to claim 1 , wherein the support bears the cradle, and the cradle bears a bracket.
