Abstract
The laying of pieces 40 of cord 4 is assured by a laying tube 30 which receives the cord by placing its inlet facing the outlet of a cord distributor, the knife 85 of which cuts the cord just upstream of the laying tube 30. At the end of the laying tube 30 there is disposed a laying head 32 which is displaced transversely along the support 1 on which the reinforcement is built. The angle of laying of the cord is adjusted by judiciously coordinating the transverse speed of displacement of the head 32 and the speed of rotation of the support 1.
Claims14
A machine for the manufacture of a crown reinforcement for tires, comprising a cord distributor, members for laying a cord at the desired place on a support and means for driving the support in rotation around its axis of symmetry of revolution, characterized by the fact that the outlet of the cord distributor delivers the cord to the laying members at a point fixed in space, located radially above the support, and by the fact that the laying members comprise
- at least one laying tube arranged downstream of the cord distributor, the cord delivered being threaded into the inlet of the laying tube while the inlet is substantially opposite said outlet of the cord distributor and at a slight distance from it, the cord moving within the laying tube to the outlet thereof
- laying head connected to the outlet of the laying tube to lay the cord on the support and
- means for transversely displacing the laying head across the support and further comprising cord cutting means intermediate the outlet of the distributor and the inlet of the laying tube.
A machine for the manufacture of a crown reinforcement for tires comprising a support which is rotatable on an axis, the outer surface of the support receiving different components of the tire in the order and place required by the architecture of said tire and on which a crown reinforcement is formed by laying individual pieces of cord diagonally and transversely across the support, the pieces of cord being adhesively maintained on the support, a laying head carried transversely across the support, a tube having an inlet end for receiving the cord and an outlet end for directing the cord to the laying head, means for adjusting the length of the tube to adapt it to the length of the cord to be laid, means for feeding the cord from a source to a fixed point in space and for introducing the cord into the inlet of the tube at that fixed point and cutting means located intermediate the feeding means and the tube inlet at such fixed point for cutting a length of cord.
