Embodiment Construction

[0046] In the context of this application, a material or compound that is a very weak conductor means a material or compound with a resistance greater than or equal to 10 8 Ohmic material, conductive material or compound is one with a resistance of less than 10 6 ohmic material.

[0047] In the present invention, the term longitudinal or longitudinally is used to denote the direction corresponding to the longitudinal direction of the tread, which is in the form of a flat strip before being added to the green annular tire assembly. The term transverse means a direction perpendicular to the longitudinal direction of the tread.

[0048] figure 1A strip laying device according to a first embodiment of the invention is shown. The device comprises means 3 for supporting the tread 2 and a frame 4 for supporting the components of the device. The mechanism 3 comprises a plurality of support rollers 5a, 5b, 5c mounted at a distance from each other and free to rotate about axes paral...

Abstract

A device for fitting a strip (12) to the reception surface of the tread base (2a) of a tread (2) with a longitudinal axis X-X', comprising: -a frame (3) for supporting the tread, extending in a direction parallel to the axis X-X'; -a strip distribution module (90) cooperating with a fitting head (60) provided with at least one roller (73, 74) for applying the strip to said reception surface, the fitting head being supported by a carriage (61) that is translationally movable in a direction parallel to the plane of the reception surface; -the fitting head comprising means for cutting a section of the strip. The fitting head comprises means for continuously retaining the strip, before and after the cutting of a section of the strip.

Description

technical field [0001] The present invention relates to a device and a method for fitting a partial conductive strip to a tread made of an elastomeric compound, preferably a device and a method for fitting a partial conductive strip to a tire tread method. Background technique [0002] The tire generally comprises a bead extending through a sidewall connected to a crown region comprising a crown reinforcement covered radially on the outside by the tread. Treads are generally made from a non-conductive elastomeric compound. More specifically, in order to reduce the rolling resistance of the tire, the tread is made of an elastomeric compound with a small amount of carbon black filler, and the elastomeric compound contains, by way of the main filler, a non-conductive filler such as silica. Such treads do not allow the removal of static charges, which thus build up inside the tire and cause shocks experienced by the driver, tire aging, and the like. Therefore, there is a need...
