Abstract:
An apparatus for producing a tire carcass, comprising:a substantially toroidal carrier for supporting a rubber member of a tire; an indexing mechanism for causing an indexing movement of the carrier by a predetermined angle about a rotational axis of the carrier; a feed mechanism having a cord outlet guide for feeding a carcass cord toward an outer surface of the carrier, said feed mechanism being reciprocable in the axial direction of the carrier within a surface region thereof, that extends axially of the carrier between positions of the carrier corresponding to a bead portion and a tread end portion of a tire, respectively; and pressure mechanisms forming at least a pair and arranged adjacent to opposite ends of said surface region of the carrier, respectively, so that the carcass cord fed from the feed mechanism is wound about the respective pressure mechanisms and urged thereby toward the outer surface of the carrier, wherein each pressure mechanism of said pressure mechanisms forming the pair further comprises a pin for the carcass cord to wrap around, and a block for restraining the carcass cord, wherein the pin and the block are coaxial, and the pin and the block are urged in respective sequence towards the outer surface of the carrier.
