摘要:
A method of, and apparatus for, handling a first die unit usable on a sheet extrusion system. The method includes the steps of: obtaining a carriage; placing the first die unit in a supported staging position on the carriage, the carriage configured so that with the first die unit in the supported staging position the first die unit can be moved guidingly around an axis; with the first die unit in the supported staging position, moving the first die unit guidingly around the axis to a desired angular orientation to thereby facilitate access to one or more identified regions of the first die unit; and performing an operation at the one or more identified regions of the first die unit.

A diverter valve for extruded materials, including a split cylinder in the cylindrical opening of a base, each cylinder half being independently pivotable. The base includes first and second inlets for first and second extruded material, and first and second outlets for the material. Base first and second flow paths carry the first and second extruded materials from the inlets to the output openings, and third and fourth flow paths carry extruded material from the first and second first inlet openings to the first and second outlets. The first and second inlet openings and the first and second output openings are axially open to the central opening, and the cylinder halves are adjacent along a plane substantially radial to the central opening axis with each of the cylinder halves including a recess open along the radial plane.
摘要:
A polymer filter assembly through which flowable material from a supply is directed for processing before passing to a die assembly through which the flowable material is delivered to form a sheet layer. The polymer filter assembly has a polymer filter frame that supports processing components for the flowable material and a support assembly for the polymer filter frame. The support assembly includes components cooperating between the polymer filter frame and a base upon which the polymer filter frame is supported to allow controlled relative vertical movement between the polymer filter frame and base to thereby permit controlled alignment between the polymer filter frame and at least one of: a) an upstream component that delivers flowable material from the supply; and b) the die assembly.

A barrel assembly through which flowable material is delivered to a die assembly through which the flowable material is delivered to form a sheet layer. The barrel assembly has: a conduit having a body with a length defining a lengthwise flow passage between upstream and downstream ends; and a support assembly for the conduit. The support assembly has: a) a conduit engaging assembly; and b) a guide assembly through which the conduit body and conduit engaging assembly are moved guidingly relative to a base, to which the guide assembly is mounted, in a path that is substantially parallel to the length of the conduit body.
摘要:
A roll stand assembly for processing a sheet product with a plurality of rolls on a frame. A first roll has a first sheet engaging surface and a first shaft assembly. A second roll has a second sheet engaging surface and a second shaft assembly. The first and second rolls are relatively movable between: a) an operating relationship; and b) an open relationship. A safety assembly prevents inadvertent changing of the first and second rolls from the open relationship into the operating relationship. The safety assembly includes a first chuck component mounted for movement relative to the frame between: a) a running position wherein the safety assembly is in a disengaged state; and b) a lockout position.
摘要:
A support system through which a first extrusion roll is operatively mounted upon a frame. The first extrusion roll has a shaft that has a first operating axis and axially spaced first and second ends. A first support assembly at the first shaft end has a first housing. A second support assembly acting between the frame and the first support assembly and has a second housing. The second housing is movable relative to the frame to selectively change a relationship between the first extrusion roll and a second extrusion roll on the frame that has a second operating axis and cooperates with the first extrusion roll during formation of a product. The first housing is movable guidingly relative to the second housing along a first path to thereby change an angular relationship between the first and second operating axes.

A diverter valve controlling input of two different extruded materials has a valve body having an axially extending opening, and a valve piston axially movable in the opening between first and second positions. The body defines a first inlet for receiving a first material, and a second inlet for receiving a second material with first and second outlets opposite the inlets. The piston has first and second through channels and first and second cross-over channels, each with inlet side and outlet side ports. A first flushing channel communicates with the first inlet and end ports, a second flushing channel communicates with the second inlet and end ports, and a third flushing channel opposite the first two communicates with the second outlet and includes a plurality of ports, with all the ports, inlets and outlets open to the axial opening.
