Rigid mould for moulding rubber tyres, constituted by a core 3 for defining the inner shape of the tyre, lateral portions 2 and a ring 1 of sectors. So as to be able to close such a mould, all the parts are designed to slide over each other during the final phase of their closing movement.

The manufacture of a reinforcement for a tire comprises the following steps: (a) a continuous cord is hooked to retention means disposed in two circles which are a distance apart which corresponds to the length of the path of a 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 m...

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 c...
