    摘要： For the extrusion of a calibrated profile of a thermoplastic polymer onto articles, the polymer, which is melted in an extruder (17), is fed, via a heated pressure hose (22), to an extruder head guided by a robot (5) and, by means of said extruder head, extruded and deposited on the article. At the end of each extrusion operation, the material flow to the extruder head is maintained and, by means of a change-over valve within the extruder head, redirected into an outlet orifice provided in the vicinity of the die orifice until the commencement of the subsequent extrusion operation. The redirected material flow emerges from a pipe connector (29) which is arranged on the extruder head and is coupled to a coupling piece (33). The material collected in this manner may be pelletized and fed back to the feed hopper (16) of the extruder (17).

    摘要： Apparatus for preparing a plasticated material from solids introduced into the apparatus, the apparatus including a barrel having a screw conveyor therein defining a channel for conveying the material downstream as the material is melted within the channel and a passage communicating with the channel at a downstream location and an upstream location, the locations being chosen such that unmelted solids enter the passage at the downstream location and are carried through the passage in an upstream direction, bypassing the channel, to be reintroduced into the channel at the upstream location.

    摘要： An extrusion apparatus having a rotor member rotatable within a barrel member longitudinal and cross-sectionally mixes and extrudes thermo-plastic and thermo-setting materials. The apparatus is articulated into sections including a barrel entrance and forcing section, a blending section, and an end discharge section. The barrel entrance and forcing section consists of helical extrusion grooves which terminate at an abrupt rotor to barrel and barrel to rotor material transfers. The blending section recognizes that blending is volumetric i.e. three-dimensional and therefore longitudinal displacement of the material in relation to itself is one of the dimensions. Longitudinal displacement is accomplished in the blending section by providing a double extrusion capacity main extrusion rotor and a single capacity backfeed rotor arranged to recirculate half of the material processed by the main stream rotor. The blending section is followed by the end extrusion section, which at its lead end is provided with rotor to barrel and barrel to rotor material transfers to cross shear the material in two different directions to complete volumetric blending. The material transfers are followed by helical rotor extrusion grooves as required to build extrusion pressure.
