Abstract

1337564 Moulding endless belts J S HEATON J J S HEATON and J R S HEATON [trading as JOSEPH DEWHIRST & CO] 3 Nov 1970 [29 April 1970] 52151/70 Divided out of 1335811 Heading B5A A rod 18 of polyurethane elastomer (which is cut and joined by fusion at its opposite ends to form an endless belt e.g. as in Specification 1,335,811, is extruded as a circular or "V" section from a die head 16; cooled by a water spray 26 and by passage through a cold water tank 20; and is then stretched between two roller sets, 32 and 34, within a water tank 28, which may optionally be heated by an electric immersion heater 30, prior to coiling on a windup roller 36. The roller sets 32, 34, each comprise an upper driven roller, 48 or 60, and lower idler rollers, 62 or 64, all provided with helically grooved peripheries around which the rod 18 coils. The upper roller 48 is driven from an infinitely variable gear-box 42, and the upper roller 60 is driven from the roller 48, through a further infinitely variable gear-box 54. Stretching may occur between the die 16 and the rollers 32, but is preferably effected in the tank 28 e.g. at a drawing ratio of four to one, with relaxation to substantially the original dimensions between the rollers 34 and wind-up roller 36. Maximum elasticity is obtained if the rod 28 is drawn in cold or cooled water in the tank 28, the effect of heating by the heater 30 being to reduce the elasticity of the rod 18. The rod 18 passes through sealing glands at either end of tank 20, from which water issuing is collected in a trough 22 connected to a drain 24.
