Abstract: An apparatus for detaching a supporting fabric from a substantially-elongated piece of elastomeric material includes at least one plane for supporting the piece, first rollers located close to an exit edge of the plane, at least one second roller, and at least one actuator for moving the second roller. The second roller moves between a first position, not in proximity to the first rollers, and a second position, in proximity to the first rollers. In the second position, the first rollers and the second roller detach the fabric from the piece.

Abstract: A method for detaching a supporting fabric from a substantially-elongated piece of elastomeric material includes the steps of setting heights of a distributor and a feed device, transferring the piece from the distributor towards the feed device, and detaching the fabric from the piece during the transferring step. The heights are set before the transferring step so that, during the transfer, the piece moves along a substantially-continuous and substantially-horizontal path. A related apparatus includes at least one plane for supporting the piece, first rollers located close to an exit edge of the plane, at least one second roller, and at least one actuator for moving the second roller. The second roller moves between a first position, not in proximity to the first rollers, and a second position, in proximity to the first rollers. In the second position, the first rollers and the second roller detach the fabric from the piece.

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: The present invention relates to a method for detaching a supporting fabric (51) from a substantially long piece of elastomeric material (50) to which it is attached, prior to transferring said piece to a tyre manufacturing drum. Said method includes the steps of automatically detaching the supporting fabric from the elastomeric piece and, at the same time, moving said elastomeric piece towards a feed device (30) located upstream from said manufacturing drum in order to effect said transfer. The present invention also relates to a device (10) for performing said detachment automatically.
