Abstract

12,943. Jackson, W. J. Mellersh-, [Rubber Regenerating Co.]. Sept. 9. Pug-mills.-In order to remove air which may be incorporated in rubber prior to its vulcanization, the rubber, together with the vulcanizing- agent is subjected to a treatment by which it is continually opened up in the presence of an enveloping vacuum. Fig. 1 shows the application to a tubing-press. The mixture is introduced through the hopper 19 into the chamber 16 provided with a screw 7 by which the material is opened up and finally extruded through the opening 3. Pipes 21 connected to an air-pump maintain the vacuum. In another form of apparatus, the hopper is provided with a feedscrew.
