Abstract

<PICT:0978013/C3/1> <PICT:0978013/C3/2> A method of vulcanizing rubber comprises passing a vulcanizable rubber composition through a heated bed of fluidized solid to heat the composition to its vulcanization temperature then passing the composition through a heating chamber maintained at a temperature substantiall equal to the vulcanization temperature. As shown in Fig. I sheet rubber composition from an extruder 17 is vulcanized on passing verticall through a fluidized bed 7 and a heating chamber 10 in a cylinder 1. The bed 7 is supported by a porous tile 6 above a chamber 8 which is supplied with a heated fluidizing gas or vapour through an inlet 9, a pair of electric heating elements being positioned in bed 7. Further pairs of heating elements 12 and 13 are located in the heating chamber 10 to maintain its temperature at that of the bed 7. As shown in Fig. III the fluidized bed is supported by a porous tile 34 in a pan 31 having a gas inlet 33 the rubber 40 from an extruder 41 is passed with the aid of rollers 44 45 and 46 horizontally through the bed and then through a heating chamber 35 having a heating element 36. The chamber 35 may be horizontal as shown or oblique or vertical as indicated by the dotted lines 51 and 50 respectively. In Fig. II (not shown) the fluidize bed and heating chamber are separated by a small distance, only part of the fluidizing gas from the bed being supplied to the heating chamber.
