    摘要: An extruder screw for the processing of thermoplastics, natural rubber and other elastomeric materials, comprising a screw core and a plurality of webs spiralling around the core and forming a multi-start thread in which, for at least a portion of the length of the extruder screw, the webs each have alternating lengths of lower height and lengths of greater height and, at the trailing end, having regard to the direction of rotation of the screw, of each of the web lengths of greater height, a transverse web is provided of approximately the same height as the web lengths of lower height, such transverse webs each connecting the trailing end of a respective one of the web lengths of greater height with the leading end of one of the web lengths of lower height of the next adjacent rearward, having regard to the direction of conveyance of material through the extruder, one of the webs. Preferably the lengths of web of greater height and the lengths of web of lower height are all of equal length.

    摘要: This invention is a screw-type extruder for plastics comprising a screw in a cylinder providing a feed zone, a plasticizing zone and a homogenization zone. The screw threads in the plasticizing zone are provided with marginal passageways so small as to provide heat exchange between the plastic and the screw, the latter being heated by friction.

    摘要: An extrusion mill having a barrel in which a worm is rotatably supported, the worm having helical threads and grooves which alternate with one another and are adapted to mix and advance elastomeric stock in the barrel. The threads have crests which define a helical venting path along which fluid collected from the elastomeric stock in the barrel may be vented-to-atmosphere. The foregoing abstract is neither intended to define the invention disclosed, nor is it intended to limit the scope of the invention in any way.

    摘要: A two component mixing device is fed by a pair of conveyor screws feeding and metering the two components from containers containing same. The outputs of the conveyor screws are fed into a mixing screw of varying depth which in turn feeds a nozzle suitable, for example, for feeding a mold. All screws can be powered by a single source.

    摘要: Screw conveyors for extrusion machines, and more particularly a conveying screw of the kind adapted to be rotated in a barrel of circular cross section and comprising a central core having at least two spiral flights thereon to form a multistart thread over at least part of its length, adjacent flights defining channels therebetween down which the material to be extruded is progressed.
