<p>1,126,144. Mixing apparatus. WERNER & PFLEIDERER. 31 Jan., 1967 [11 Feb., 1966], No. 4658/67. Heading B1C. In a screw mixing or kneading machine the screw and/or the casing are made of plates bonded together face to face e.g. by welding, soft or hard soldering or by an adhesive, enabling the members to be economically formed without machining. They may be similarly attached to the shaft. The separate plates may be of different materials, thicknesses and/or sizes and may be offset to form a single, double or triple thread, or as shown, they may be grouped and have a core 1a with a periphery of a different (e.g. wear or temperature-resisting) material.</p> |
