Abstract: A process for coating vegetable-tanned leathers is provided. The process includes depositing a coating layer composed of an aqueous dispersion of polyurethane resin on a support having anti-adhesion properties, curing the coating layer on the support, depositing an adhesive layer composed of an aqueous dispersion of polyurethane resin onto the cured coating layer, applying a leather piece onto the adhesive layer, the leather piece being a vegetable-tanned leather piece, in a continuous oven curing the adhesive layer to attach the leather piece to the coating layer, and removing the coated leather piece from the support. Within the continuous oven the leather piece reaches a maximum temperature comprised between 65° C. and 75° C., with a dwell time in the oven comprised between 180 and 210 seconds.

Abstract: A tyre including two toroidal bead portions housing an annular bead bundle (121); a toroidal body ply, folded, about a respective bead bundle forming a respective turn-up; two bead fillers, each in contact with a respective bead bundle and at least partly enclosed by a respective turn-up, and two elastomeric crack control members, one for each bead portion. Each crack control member extends at a body ply ending, and each crack control member is made by a couple of strips having a differentiated stiffness along their transversal section, with a lower stiffness at a first strip adjacent to the body ply ending and a higher stiffness at a second strip in contact with the respective bundle, so that the first lower stiffness strip defines a preferential propagation path for any tyre crack originating at the body ply folded ending.

Abstract: A tire (1) has two annular beads, a toroidal body ply (2) which is wound about the two beads (3) to form two turn-ups, and two bead fillers (8). Each bead filler (8) contacts a bead (3) and is at least partly enclosed in a turn-up (4) of the body ply (2), and comprises an elastomer filler strip (9) which is wound about the bead (3) and is interposed between the bead (3) and the body ply (2) and has two opposite ends (10, 11) located on opposite sides of the bead (3) and contacting each other. An outer end (11) of the filler strip (9) of each bead filler (8) is folded into a “U” about the corresponding end of the body ply (2) so as to enclose the end of the body ply (2).

Abstract: A tyre (1), comprising: two toroidal bead portions (12), each housing an annular bead bundle (121); a toroidal body ply (10), folded, at each of its transversal ending portions (101), about a respective bead bundle (121) forming a respective turn-up (14); two bead fillers (20), one for each bead portion, each in contact with a respective bead bundle (121) and at least partly enclosed by a respective turn-up (14), which tyre (1) further comprises two elastomeric crack control members (21), one for each bead portion (12), wherein each crack control member (21) extends at a body ply ending (101), externally to the respective turn-up (14), and each crack control member (21) is made by a couple of strips having a differentiated stiffness along their transversal section, with a lower stiffness at a first strip (201, 211) adjacent to the body ply ending (101) and a higher stiffness at a second strip (202, 212) in contact with the respective bundle (121), so that the first lower stiffness strip defines a prefe

Abstract: A tyre (1) having: an at least partially turned-up body ply (3); two beads (4) arranged on opposite sides of the body ply (3) and surrounded by the body ply (3); a tread (7) supported by the body ply (3); two side walls (11) arranged outside the body ply (3) between the tread (7) and the beads (4); and two abrasion gum strips (12) located externally below the sidewalls (11) and at the beads (4); wherein a joining surface (13) between each side wall (11) and the corresponding abrasion gum strip (12) has in cross-section a “U”-like shape (FIG. 3).

Abstract: A tyre (1) and method for building a tyre (1), wherein the tyre has: two annular beads (3); a toroidal body ply (2) which is wound about the two beads (3) to form two turn-ups (4); and two bead fillers (8), each one thereof contacts a bead (3), it is at least partly enclosed in a turn-up (4) of the body ply (2) and comprises an elastomer filler strip (9) which is wound about the bead (3), it is interposed between the bead (3) and the body ply (2) and has two opposite ends (10, 11) located on opposite sides of the bead (3) and contacting each other; an outer end (11) of the filler strip (9) of each bead filler (8) is folded into a “U” about the corresponding end of the body ply (2) so as to enclose the end of the body ply (2).
