Abstract:
An apparatus for manufacturing a tire reinforcement, said apparatus being intended for manufacturing a reinforcement constituted from a cord supplied continuously and on demand by a suitable distributor, said apparatus being intended for use in cooperation with a substantially toroidal form on which said reinforcement is built up progressively by laying down arches of said cord, according to a desired trajectory for said cord, on the surface of said form, said apparatus comprising:a guide member in which the cord may slide freely, means for displacing said guide member in a cyclical, to-and-fro, movement, to bring said guide member in successive cycles into the vicinity of each of the desired ends for the cord in said trajectory, pressers close to each end of said trajectory, for applying the cord onto the form at said ends, characterized in that: the displacement means comprises at least one base arm, said base arm comprising a center of rotation and a conveying head, and control means for imparting to said base arm an oscillatory movement about said center of rotation, the apparatus being arranged so that the conveying head of said base arm conveys the guide member from one end to the other of said trajectory, the geometric axis of said center of rotation is, in the working position, entirely exterior to the form.
