Claim:
A method of manufacturing a tire reinforcement from a cord supplied continuously and on demand by a cord distributor, using a revolving form having an axis of rotation and on which the tire reinforcement is progressively built up, the method comprising: depositing on the revolving form a layer of raw rubber at least in zones where ends of the tire reinforcement are anchored, wherein the revolving form is driven in rotation continuously, the cord is held on the revolving form in an anchoring zone, a depositing element in which the cord is threaded is made to describe a reciprocating motion about the revolving form and to synchronize with the rotation of the revolving form in order to deposit progressively a first cord section during an outward movement of the depositing element and a second cord section during a return motion, the ends of each the first and second cord sections are temporarily pressed against the revolving form in the anchoring zones, and while the depositing element performs its reciprocating motion, a mobile guide is so acted on as to move, in a circumferential direction, a portion of the first and second cord sections disposed between the depositing element and the revolving form, in order to form part of a final trajectory made by cord sections deposited on the revolving form, and repeating the aforesaid movements to deposit additional cord sections on the revolving form, along the final trajectory for the cord sections on the revolving form.
