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.
