Process and apparatus for manufacturing tyres for vehicle wheel

摘要

A process and apparatus for manufacturing tires for vehicle wheels includes the step of building, on a forming support, a belt structure including at least one reinforcing structure of the so-called zero-degree type. The reinforcing structure is formed by depositing a continuous elongated reinforcing element on a deposition surface arranged in a radially outer position with respect to the forming support. The aforementioned deposition includes the step of exerting, through at least one element made from magnetic material, a magnetic attraction on a portion of the continuous elongated reinforcing element arranged at at least one pressing member and moving said at least one pressing member toward the forming support until the continuous elongated reinforcing element is brought into contact with the deposition surface.

1. A process for manufacturing a tyre for vehicle wheels, the tyre comprising a belt structure arranged between a carcass structure and a tread band, wherein the belt structure comprises at least one zero-degree reinforcing structure, comprising:
building said zero-degree reinforcing structure by depositing a continuous elongated reinforcing element on a deposition surface arranged in a radially outer position with respect to a forming support, the deposition comprising: exerting a magnetic attraction on a portion of the continuous elongated reinforcing element via at least one deposition pressing member;
wherein said deposition pressing member comprises at least one pressing roller;and wherein said magnetic attraction is generated through at least one element made from magnetic material arranged on said at least one pressing roller; moving said at least one deposition pressing member toward the forming support until the continuous elongated reinforcing element is brought into contact with said deposition surface; moving said at least one deposition pressing member away from the forming support; and depositing the continuous elongated reinforcing element on the forming support by feeding the continuous elongated reinforcing element while keeping said at least one deposition pressing member in the moved-away position and while exerting the magnetic attraction on the continuous elongated reinforcing element through the at least one element made from magnetic material arranged on said at least one pressing roller of said at least one deposition pressing member.
