Abstract
Apparatus for making a reinforcement for a tire including: (a) cord retention means disposed in two circles which are a distance apart which corresponds to the length of the path of the cord from one side of the reinforcement to the other so that the cord, disposed in this way, defines a cylinder by a plurality of passes back and forth from one retention means to another, (b) by a suitable movement of the retention means, the cord which is disposed in this way is folded back on and around a core defining the shape of the inner surface of the tire, (c) the anchoring of the cord being assumed, the retention means are released.
Claims12
An apparatus for the manufacture of a tire having at least one reinforcement formed from a continuous cord, comprising:
- (a) two rings of support arms the axially inner end of which
- can be displaced axially and radially
- bears retention means for the cord;
- (b) a rotary arm
- whose axis of rotation is
- substantially perpendicular to the axis of the rings
- located substantially axially midway between the retention means
- which bears delivery means making it possible to hook the cord to the retention means upon each passage of the rotary arm, the two rings turning through an angle corresponding to the distance between two adjacent retention means, upon each turn of the rotary arm;
- (c) means for permitting insertion of a rigid core radially within a cylinder formed by the retention means.
