Patent ID: 6913058

Claim:
A device for producing a body ply material for a pneumatic tire, comprising: a ribbon manufacturing device for manufacturing a ribbon of a predetermined width dimension in the form of a cord having a rubber covering applied thereto; a ribbon winding mechanism for spirally winding said ribbon on an outer peripheral surface of a drum; and a bonding mechanism for bonding lateral edges of the ribbon to manufacture a wrapper; a peripheral length dimension of the outer peripheral surface of said drum being set equal to or integral multiples of a width dimension of a body ply material for use in a tire; a winding length in a drum longitudinal direction of said wrapper being set equal to a length dimension of said body ply material for use in a tire; a wrapper cutting mechanism for cutting said wrapper along a gentle curve which is substantially orthogonal to the longitudinal direction of the ribbon to form the body ply material of a predetermined width dimension; a body ply material peeling mechanism for peeling the body ply material from the drum; and a tray for receiving and supporting the body ply material peeled from the drum, said tray having a plurality of vacuum pads for adsorbing the peeled body ply material on the tray and being transported to a direction intersecting the axial line of the drum by a tray transporting mechanism; wherein said body poly material peeling mechanism comprises a peeling tool for partially peeling an edge of a cut body ply material, following cutting of the wrapper, and a rotating peeling bar entering a gap of the cut edge, formed by the peeling tool, to transfer the body ply material onto the tray.
