Abstract: 1506714 Moulding tyres DUNLOP Ltd 19 May 1975 [28 May 1974] 23575/74 Heading B5A Apparatus for use in moulding the tread portion of a pneumatic tyre includes a solid, elastomeric annular former 10, stretching means, e.g. platens, 29, 30, Fig. 1, to increase the former diameter and supporting surfaces 14, 15 engaging the inner periphery of the former; after positioning an inextensible breaker structure around the former, the stretching means causes the former to expand to place the breaker structure in tension and when subsequently the tread portion is moulded on to the radially outer surface of the former over the breaker structure the supporting surfaces prevent radially inward deformation of the former. The breaker structure is applied to the former after reducing the diameter of the former by opposed clamping members, not shown. As shown the former is T-shaped with an annular stem portion 16 and a rib 17. Tyre sidewall portions such as 48, Fig. 5, are located or moulded in contact with the tread portion 47 and the assembly cured. Radially extending metallic stalks 18 with enlargements 19 may be used to remove the former from the cured tyre. As shown in Fig. 5 the former may include pockets 41 at its ends formed by bending back membrane portions 45 into slits to thereby provide means to grip the edges of the breaker assembly. When the assembly and tyre sidewalls are positioned in a mould the pockets are inflated and the membrane portions forced outwardly causing the breaker edges to engage tyre sidewall reinforcements.

The temperature of material 12, such as cement, in a rotary furnace is measured by a pyrometer 5 receiving radiation through a spy hole 4 through which air is blown by a blower 7 to cool the pyrometer and clear the spy hole. The spy hole is formed in a replaceable section 3 of the furnace and may taper towards the pyrometer 5. As the furnace rotates the pyrometer sees the surface of the material 12, the body of the material 12 and the furnace gases and wall above the material 12 in turn. The pyrometer signal in each of these periods may be gated to different control means. A hole 9 is provided to allow release of pressure if the spy hole is blocked by a large piece of material. A plurality of pyrometers may be spaced along the furnace. A flap which closes when the temperature reaches a predetermined level may be provided to protect the pyrometer.

A previously extruded cable core 1 wherein a thermoplastic dielectric 3, particularly polyethylene, surrounds a central conductor 2, is drawn through a metal, preferably brass, die 4 with a conical entrance 6 and surrounded by an electric heater 7, temperature-controlled through a variable transformer. As the core passes through the hole 10, which is smaller in diameter, excess dielectric material is melted and sheared off, the core thus being sized or swaged within close tolerance. Waste material accumulates in the opening 6 and centres the core, also preheating it. A recess 12 at the die exit, by causing a time interval before the sized core comes in contact with the outside air, acts as an annealing zone. Precision guide rollers 5, 13 ensure that the core passes exactly through the die centre. A higher degree of dimensional control may be attained by drawing the core through several dies in succession. The sizing process has other applications e.g. to plastic rod and tubing.
