  • Patent number: 10730198
    Abstract: Within tyre manufacturing, a reinforcing structure of the tyre, such as the zero-degree layer of the belt structure, is made by an apparatus having devices for guiding a continuous elongated element towards a forming drum, devices for applying the elongated element against a laying surface of the drum, and a cutting unit to cut off the continuous elongated element when application has been completed. Once the cutting operation has been carried out, the free end of the continuous elongated element is set to a grip position downstream of the cutting unit, through a reciprocating slider and a threading element blocking the continuous elongated element with respect to the slider when the latter moves towards the forming drum.

  • Patent number: 10710323
    Abstract: Process and apparatus for applying noise reducing elements to tyres for vehicle wheels. The apparatus includes a loading station of stacks of noise reducing elements, an extraction station of noise reducing elements from each stack placed downstream of the loading station, and a conveyor placed downstream of the extraction station and extending along a predefined path. The conveyor is configured for supporting and advancing in a row the noise reducing elements extracted from the stacks which are then applied to a radially inner surface of the tyres. The extraction of each of the noise reducing elements contemplates: retaining a first noise reducing element placed at the base of a stack; raising the remaining noise reducing elements of the stack from the first noise reducing element; moving away the first noise reducing element according to a set path; and lowering the remaining noise reducing elements of the stack.

  • Patent number: 10697762
    Abstract: An apparatus for checking tires described as a linear camera having an objective line lying on an optical plane; a first, a second and a third light source for emitting respectively a first, a second and a third light radiation; a command and control unit for selectively activating at least one from among the first, second and third light source and activating the linear camera in order to acquire a two-dimensional image of a linear surface portion of the tire synchronously with the activation of the first, second and third source. The first and second light source lie on opposite sides of the optical plane. Furthermore, the first, second and third light source include each one or more sub-sources each having a respective main extension direction parallel to the optical plane and the distance of the sub-sources of the third light source from the optical plane is less than the distance of the first and second light source from the optical plane.

  • Patent number: 10697857
    Abstract: A method and apparatus for checking tyres in a tyre production line. The method includes alternately illuminating, with a first and second grazing light radiation, a surface portion of the tyre and respectively acquiring a first and second two-dimensional digital image of the illuminated surface portion. For each point of the surface portion, the respective overall light power of the first and second light radiation incident at the point respectively comes from two half-spaces that are opposite with respect to an optical plane passing through the perpendicular to the surface at the point; and comparing the first and second image to obtain information on an altimetric profile of the surface portion.

  • Publication number: 20200198273
    Abstract: The invention relates to a toroidal forming drum and a process for building tyres. The toroidal forming drum (23) is expanded within a shaped carcass sleeve (12), for supporting the carcass sleeve (12) against an abutment surface (“S”) externally provided by the forming drum (23). An elementary semi-finished product (54a, 54b) is applied around the shaped carcass sleeve (12), by pressing said elementary semi-finished product (54a, 54b) towards the abutment surface (“S”). The abutment surface (“S”) has circumferential rows of solid portions (40) alternated with hollow portions (41). The solid portions (40), arranged along axially opposite circumferential edges of the abutment surface (“S”), have a transverse size comprised between 10% and 60% of a transverse size presented by the solid portions (40) arranged in proximity to an axial centreline plane of the abutment surface (“S”).
