Abstract
A process for producing a tire reinforcement is characterized by the fact that each reinforcement cord is projected individually into its place in the reinforcement. For this purpose, a machine is used which comprises laying members comprising essentially a rotary conduit which projects the cord by a radially outer extremity of the conduit and rollers which impose a linear speed of laying of the cord.
Claims6
A process for producing a tire reinforcement, the reinforcement comprising adjacent, substantially parallel cords, characterized by the fact that each reinforcement cord is projected individually to move in a plane and through an arc into its place in the reinforcement, the reinforcement being produced on the outer surface of an element which defines the geometry of the reinforcement, the cord being projected across the outer surface of the element, the outer surface of the element and the cord having self-adhering properties.
A process for producing a tire reinforcement, the reinforcement comprising adjacent, substantially parallel cords extending across the width of the surface of the tire to receive the reinforcement, characterized by the fact that a continuous cord is advanced to the surface of the tire to receive the reinforcement and a cut end is projected through an arc into its place on the reinforcement and the cord is cut to produce the cut end of the next reinforcement cord to be projected, the surface of the tire and the cord having self-adhering properties.
