TRANSFER WHEEL AND METHOD FOR TRANSFERRING A STRIP TO A TIRE BUILDING DRUM
20220332070 · 2022-10-20 ·

Disclosed is a transfer wheel, a transfer device and a method for transferring a strip, in particular a run-flat reinforcement strip or a sidewall strip, to a tire building drum, wherein the transfer wheel defines a retaining area that is divided into a first end section for retaining the leading end, a second end section for retaining the trailing end and a main section for supporting the strip body. The transfer wheel has a first mounting member that defines first mounting positions for receiving a first group of retaining segments at the first end section, wherein the first group of retaining segments includes first body retaining segments for retaining the strip body and a first end retaining segment for retaining the leading end, wherein the first mounting member is arranged for interchangeably receiving one first body retaining segment or the first end retaining segment in each first mounting position.

TIRE HAVING IMPROVED UNIFORMITY AND METHOD FOR MANUFACTURING SAME
20230158762 · 2023-05-25 ·

A method for manufacturing a tire comprising a carcass reinforcement comprising a carcass layer and a working reinforcement comprising a single working layer comprising forming, around a support, a wound carcass assembly (52) intended to form the carcass layer and a wound working assembly intended to form the working layer, and then deforming the support. The wound carcass assembly (52) is formed so as to form either a junction (56) by abutment without forming a superposition, or a junction (56) by overlapping, or without forming a junction.

APPLICATOR ROLL, TIRE COMPONENT SERVICER AND METHOD FOR APPLYING A STRIP TO A DRUM
20230070473 · 2023-03-09 ·

An applicator roll, a tire component servicer, and a method for applying a strip to a drum are provided. The applicator roll includes an outer ring that is rotatable about a rotation axis and that defines a retaining surface. The applicator roll is provided with suction openings for retaining the strip to the retaining surface. The applicator roll includes a follower that is rotatable inside the outer ring to follow a part of the strip on the retaining surface. The follower defines a chamber that extends in the circumferential direction over a retaining arc along the outer ring. The follower is rotatable about the rotation axis independently of the outer ring to a first retaining position on the outer ring in which the chamber is arranged in air communication with one or more suction openings within said retaining arc.
