Abstract

391,253. Extruding rubber articles. GARE, T. and GARE, G., c/o Hazel Grove Rubber Co., Bramhall Moor Lane, Stockport. Dec. 15, 1931, No. 34699. [Class 87 (ii).] Ribs formed on extruded rubber articles by the extrusion nozzle are converted into studs by moving moulds which operate before the articles have attained their final degree of elasticity. The extrusion nozzle 1 is formed with longitudinal internal ribs 4 and has a projecting lip 2 which is detachably secured thereto by screws 23 and forms a guide channel 3 to support the tyre &c. extruded from the nozzle 1. A wheel 5 is adjustably mounted in slots 7 in a bracket 8, detachably fitted on the nozzle 1. The periphery of the wheel 5 has a number of blunt cross ribs 12, 13 which are pressed into the surface of the extruded rubber to mould it. The ribs 12, 13 may either be offset or may extend right across the wheel. If more than one surface is required to be moulded, as in pedal rubbers, several wheels 5 may be employed and the lip 2 may be dispensed with. The nozzle 1 and wheel 5 may be heated by a burner or jacket. Either revulcanized waste rubber or fresh rubber dough may be used.
