    摘要: A liner for a double-worm or double-screw extruder housing having a longitudinal passage having the configuration of a pair of parallel intersecting cylindrical bores having a common chord or secant plane is formed of a pair of mirror symmetrical parallel cylindrical segmental tubes joined along a common chord plane constituting a symmetry plane parallel to the segment axes. The tube segments are butt-welded together at this chord plane and are formed with outwardly open notches at this chord in which the tubes are further joined together by fillet welds, i.e. deposits of weldment (deposit welds). The notches of the segments are disposed opposite one another and are longitudinally spaced apart by distances approximately equal to their longitudinal widths. On opposite sides of the liner the notches are staggered, i.e. where a pair of notches are formed in one transverse plane on one side of the liner, the other side has unnotched abutting faces and vice versa.

    摘要: Apparatus for the extrusion of cellular (foamed) synthetic resins and elastomers in which a masticated and plastified synthetic resin or elastomer mixture, blended with a foaming agent, is extruded through a nozzle, e.g., in the form of slab. The extruded slab is permitted to expand against a superatmospheric counterpressure during cooling in one or more chambers provided immediately ahead of the extrusion nozzle, the chambers being separated from one another by pressure-retaining gates or locks. Between each chamber, a driven or autorotating pair of calibrating rolls may form part of the pressure-retaining gate.
