发明名称 Method and apparatus for producing a tyre carcass
摘要 An apparatus (1) for producing a tire carcass having bead portions which are substantially free from cut surfaces of carcass cords. The apparatus includes a substantially toroidal carrier (2) for supporting a rubber member (18) of a tire. An indexing mechanism causes an indexing movement of the carrier by a predetermined angle about a rotational axis of the carrier. A feed mechanism (3a,3b) continuously feed a carcass cord (7) toward an outer surface of the carrier, wherein the feed mechanism are reciprocable in the axial direction of the carrier within a surface region (9) thereof, that extends axially of the carrier at least between positions of the carrier corresponding to a bead portion and a tread end portion of a tire, respectively. Pressure mechanisms (4a-4d) forming at least a pair are arranged adjacent to opposite ends of the 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. <IMAGE>
