Apparatus with a combination of movements for manufacturing a tire reinforcement from a single cord

A process for manufacturing a tire reinforcement constituted from a cord supplied continuously and on demand by a suitable distributor, using a substantially toroidal form on which said reinforcement is built up progressively by depositing arches of the cord according to a desired trajectory for the cord on the surface of said form, and using an apparatus comprising depositing members arranged on a support wherein said depositing members comprise:

• (a) a guide member in which the cord may slide freely and
• (b) a mechanism for actuating said guide member in a plane of movement so as to bring said guide member in successive oscillations from one end of said cord trajectory to the opposite end of said cord trajectory, said process comprising:
• (i) actuating the form with rotation at a speed which is not zero;
• (ii) moving the guide member in a first direction in said plane of movement to a first end of said cord trajectory;
• (iii) applying the cord to the form at said first end by means of a first presser;
• (iv) holding said cord to said form at said first end;
• (v) actuating said support in synchronism with the movement of said guide member so as to deflect the final cord trajectory;
• (vi) moving said guide member in a direction opposite to said first direction to a second end of said cord trajectory;
• (vii) applying the cord to the form at said second end by means of a second presser device;
• (viii) holding said cord to said form at said second end;
• (ix) actuating said support in synchronism with the movement of said guide member so as to deflect the final cord trajectory;
• (x) repeating steps ii to ix until the desired number of arches is deposited on the surface of the form.
