Abstract (en)
[origin: WO2007057234A1] Pulley, in particular for use in the drive system of a clothes washing machine to rotatably drive the drum thereof, produced by injection moulding using a plastic material filled with reinforcing glass fibres, said pulley (10) being comprised of a central hub (12) connected through a plurality of radially extending spokes (16) with a peripheral rim (18), around which there is capable of being wrapped a driving belt or the like. The plastic material is injected into the mould through a hot runner (20) a plurality of nozzles (24) arranged close to the central hub (12), so that the joining or welding spots of the plastic material are caused to occur and lie along the peripheral rim of the pulley at the melting temperature of the same plastic material, i.e. approx. 2500C.
