Embodiment Construction

[0046] The present invention relates to figure 1 , image 3 and Image 6 The machine 1 shown in particular is intended for the automatic manufacture of tires, more preferably pneumatic tires.

[0047] Said machine 1 comprises a first area 2, called "tyre building area" 2, which is designed to produce a first annular body 3 forming part of a tire (this is called "carcass body" 3), said first An annular body 3 comprising at least one carcass ply 4 provided with a first set of filiform reinforcing elements 5 called "carcass reinforcements" 5, such as figure 2 , Figure 4 and Figure 7 especially visible.

[0048] An element referred to as "filamentary" means an element extending longitudinally along a main line and having a cross-section perpendicular to said main line, wherein the largest dimension, referred to as "transverse dimension" G, is the same as that considered along said main line. The dimension called "longitudinal dimension" L is relatively small in comparison...

Abstract

The invention relates to a machine (1) for automatically manufacturing tyres. The invention relates to a tyre comprising a shaping area (2) for creating a carcass entity (3) comprising a carcass ply (4) with carcass reinforcements (5) on a drum (6), a finishing area (20) for creating a crown entity (21) comprising a tread (22), a shaping system (30) for radially expanding the carcass entity (3) to have a toroidal shape, a method for assembling the crown entity (21) on the carcass entity (3) The invention relates to a tyre (1) comprising a drum (6), an assembly area (40) thereon, a biasing system (50) for combining a biasing structure (51) with a carcass entity (3), said biasing structure (51) being provided with a biasing reinforcement (52) designed to interact with a carcass reinforcement (5) during forming in order to vary the angular orientation of said carcass reinforcement (5) with respect to the circumferential direction (C6) of the drum (6), and an automatic control unit (60), the automatic control unit (60) thereby enables a tire with a biased crown to be manufactured while providing a production of a crown entity (21) to be performed in parallel with the preparation of a carcass entity (3).

Description

technical field [0001] The present invention relates to the field of the manufacture of pneumatic tires. Background technique [0002] It is known to manufacture pneumatic tires by combining a first annular entity called "carcass entity" on the one hand and a second annular entity called "carcass entity" on the other hand ” comprising at least one carcass ply containing reinforcing threads extending in a plane that is radial with respect to the central axis of the tire and is preferably shaped by inflation so as to exhibit a torus shape, The second annular entity, called "crown entity", comprises the tread and a reinforcing ply called "crown ply", each of which is called "crown ply". Each has reinforcing filaments that are parallel to each other and inclined at an angle called the "ply angle" relative to the circumferential direction of the tire. [0003] The two crown plies with different ply angles superimposed on the carcass ply, and thus the respective diagonal reinfor...
