Abstract: A tire-assembling apparatus includes an assembling drum, radial-movement devices, and at least one axial-movement actuator. The assembling drum includes first and second halves axially opposed along a geometric axis of the drum. Each of the halves includes a plurality of circumferentially-distributed radial sectors. The radial-movement devices associated with each of the halves selectively translate corresponding radial sectors between a contracted condition and an expanded condition. The at least one axial-movement actuator translates the halves relative to each other between an approaching condition and a spaced-apart condition. Each of the radial sectors includes a holding member and a supporting member. The holding member defines an engagement seat of an annular anchoring structure to a bead-part of a carcass sleeve fitted on the drum.

Abstract: The present invention relates to an apparatus for the automatic cutting of an element (50) made of elastomeric material, comprising: a rotary blade (11) having a continuous and curvilinear cutting profile, at least one cooling unit for cooling (16) said blade, a supporting structure (12) for supporting said blade, a feed device (14) for moving said supporting structure transversely relative to said element, a motor unit (15) for spinning said blade, and at least one structure (51) for supporting and feeding said element (50) to said blade. In accordance with the present invention, the ratio of the speed of rotation of said blade to the traversing speed of said feed device is between 10 and 40. Furthermore, said cooling unit (10) conveys cold air at least onto a radially outer portion of said blade, and at least one cutting surface on said blade, interacting, during the cut, with said element (50) of elastomeric material has non-stick properties.

Abstract: Tyre building drum with turn-up apparatus for building an unvulcanized tyre with tyre components (1, 2) and two bead cores (3, 4) with high bead filling strips (4′). Said drum has two ring segments (6, 7) spaced from each other in order to support a bead core, drum segments (8, 9, 10, 11, 12) placed on the outside of each ring segment in order to support the tyre components. Said drum further has means to radially expand that part of the tyre components which is situated between the ring segments.
