  • Patent number: 5143254
    Abstract: The material to be metered drops onto a plate 21 which is driven in rotation. This plate 21 is provided on its edge with a cylindrical wall 22 pierced by recesses 24. The plate 21 turns in a cylinder 3 which masks the recesses 24 except at a place where a hole 5 is provided. When the recesses 24 pass opposite the hole 5 they pass behind a screen 4. Each recess 24 is emptied when it passes behind the screen 4 and is otherwise filled under the effect of centrifugal force.

  • Patent number: 4963207
    Abstract: The rubber products forming a part of the structure of a tire are laid onto a rigid core by means of a volumetric extruder having an outlet orifice of small size positioned close to the surface on which the rubber is to be applied. The rubber products are built up by a meridian displacement of the orifice relative to the receiving surface with the extrusion of a controlled volume of rubber.

  • Patent number: 4952259
    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.

  • Patent number: 4895692
    Abstract: A mold for molding and vulcanizing a rubber tire comprises a rigid core defining an interior surface of the tire, two side parts and a peripheral ring divided into a plurality of segments. In order to be able to close the mold, all the members are designed to slide on each other during final phase of their closing movement.

  • Patent number: 4801344
    Abstract: The manufacture of a reinforcement for a tire comprises the following ste s:(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 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 assured, the retention means are released.

  • Patent number: 4068829
    Abstract: A head for mixing and discharging at least two ingredients comprising distributor valves to mix the products, each valve having a stem associated with a lever pivoted to be controlled by a rod which cooperates with a cam ramp carried by a sliding member capable of being displaced within the head and the slide member being movable to stop distribution of the mixed product and recycle the ingredients into their separate storage reservoirs, the machine being particularly useful in connection with the making of polyurethane.
