Abstract: A cord is supplied continuously and on demand by a suitable distributor. The apparatus is used with a revolving form (1) on which the reinforcement is progressively built up by depositing sections of the cord along a desired trajectory for the cord on the surface of the form. The apparatus comprises an element for depositing the cord on the surface of the form (1), describing an alternating path between two turning points, pressers close to the turning points in order to apply the cord to the form at the ends of the trajectory, acting synchronously with the depositing element, a mobile guide (5) disposed opposite the form, in the space between the form and the path described by the depositing element, a fixed guide (6) substantially parallel to the mobile guide (5), control means for moving the mobile guide (5) in a circumferential direction, and motorization means for synchronously piloting the depositing element, the pressers, and the control means of the mobile guide (5).

Abstract: An apparatus for producing a pneumatic tire reinforcement, said apparatus being intended to produce a reinforcement consisting of a thread (2) delivered substantially continuously and on demand by an appropriate delivery device, said apparatus being intended to be used in cooperation with a substantially toroidal form (1) on which said reinforcement is progressively built up by depositing arches (3) of said thread along a desired path for said thread on the surface of said form. The apparatus includes: a thread guide (4) in which the thread can slide; means (5) for moving said guide along the desired path for said thread; and first and second pressing means (7, 8) placed respectively on either side of the form and capable of holding the thread against the form substantially at the ends (6) of said arches, wherein the pressing means comprise, at least on a side (B) of the form, a rotary pressing arm (9).

Abstract: An apparatus for manufacturing a tire reinforcement from a cord, cooperating with a substantially toroidal form on which arches of the cord are deposited according to a desired trajectory for the cord on the surface of the form, the apparatus having depositing members arranged on a support, the depositing members including a guide member in which the cord may slide freely, a mechanism for actuating the guide member in a cyclical, to-and-fro, movement, to bring the guide member in successive oscillations into the vicinity of each of the desired ends for the cord in the trajectory. The apparatus further includes a first motor imparting the desired movements to the actuating mechanism and a second motor for imparting to the depositing member support a cyclical movement synchronized with the actuating mechanism, allowing deflection of the final trajectory of the cord on the form.
