Patent number: 11207857Abstract: A method for controlling the thickness of a continuous elongated element made of elastomeric material, applied according to coils wound on a forming support, includes: advancing a head end of the continuous elongated element toward the forming support; subjecting, during the advancement, the continuous elongated element to a first stretching with a first stretch coefficient before applying on the forming support; and subjecting, during the advancement, the continuous elongated element to a second stretching with a second stretch coefficient during the application on the forming support. During the first stretching, a span of the continuous elongated element adjacent to the head end is stretched with a supplementary stretch coefficient greater than the first stretch coefficient, in a manner so as to confer, also to the span adjacent to the head end, a stretch and a section similar or substantially equivalent to those of the rest of the continuous elongated element.Type: GrantFiled: November 14, 2018Date of Patent: December 28, 2021Assignee: PIRELLI TYRE S.p.A.Inventors: Marco Fabbretti, Andrea Crepaldi, Cesare Emanuele Amurri, Maurizio Marchini

Patent number: 10926501Abstract: A reinforcement annular structure of a tyre being processed is formed by arranging a forming drum externally carrying a deposition surface; arranging an application member supported in thrust relation toward the deposition surface; longitudinally guiding a continuous elongated element toward a point of application between the deposition surface and a work surface presented by the application member; and winding the continuous elongated element circumferentially around the deposition surface in order to form coils that are axially side-by-side each other. During winding, the work surface of the application member operates in abutment relation against at least one of the cons previously formed by the continuous elongated element.Type: GrantFiled: November 26, 2015Date of Patent: February 23, 2021Assignee: PIRELLI TYRE S.p.A.Inventors: Maurizio Marchini, Cesare Emanuele Amurri, Marco Fabbretti, Andrea Crepaldi
