20100300171 | Height positioning mechanism for roll stand assembly on an apparatus for continuously forming an extruded sheet product - An apparatus for continuously forming an extruded sheet product having an extruder assembly with a sheet die for delivering flowable material. A roll stand assembly has a main frame with first and second rolls. A vertical height positioning mechanism is operated to vary the relationship between the sheet die and nip location between rolls and has first and second lift components that cooperate with the main frame at first and second laterally spaced locations. The first and second lift components are each movable in first and second opposite paths to selectively elevate and lower the nip location relative to the sheet die. The vertical height positioning mechanism further has an actuating system to selectively and simultaneously cause the first and second lift components to move. | 12-02-2010 |
20100301507 | Gap adjusting mechanism for rolls on a roll stand used in the extrusion forming of a sheet product - A roll stand for use in the extrusion forming of a sheet product from a flowable material having a main frame supporting first and second rolls between which there is a first gap through which at least one sheet layer passes during sheet product formation. A first adjusting mechanism moves the first roll relative to the second roll so as to vary a dimension of the first gap. The first adjusting mechanism has a first element that is moved by a first actuator that is: a) maintained on the apparatus; b) engageable by a hand of an operator; and c) manually movable through an operator's hand to thereby cause repositioning of the first roll. | 12-02-2010 |
20100301513 | Sheet coating system on an apparatus for extrusion forming a sheet product - An apparatus for extrusion forming a sheet product having an extruder assembly with a sheet die through which a flowable material is delivered and a roll stand assembly made up of a roll stack sub-assembly and a sheet take-off sub-assembly. The roll stack assembly has first and second rolls between which a nip location is defined at which flowable material from the sheet die is delivered. The sheet take-off sub-assembly produces an advancing force upon a first sheet component made up of at least the first sheet layer. The roll stand assembly further has a coating system for applying a coating component to a surface on at least one sheet component advancing through the apparatus. The roll stand assembly is constructed to be reconfigured thereby to change a path traveled by the at least one sheet component and facilitate selective application of the coating component. | 12-02-2010 |
20100303943 | Linear bearing assembly to guide movement of roll stand on apparatus for forming an extruded sheet product - An apparatus for forming an extruded sheet product having an extruder assembly with a sheet die through which flowable material is delivered for sheet product formation and a roll stand assembly with a main frame and a roll stack sub-assembly on the main frame that cause flowable material from the sheet die to be formed into a sheet product. The apparatus further has a sub-frame assembly and a linear slide bearing assembly with at least one rail defining a travel path for the main frame and through which the main frame is guided in movement relative to the sub-frame assembly, thereby to selectively vary relative positions of the sheet die and roll stand assembly along the travel path. | 12-02-2010 |
20120073687 | Diverter Valve - A diverter valve controls input of two different extruded materials to a mold. A valve body has an axially extending opening, and a valve piston is 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. 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. The piston has first and second through channels and first and second cross-over channels, each with inlet side and outlet side ports. In the first position, the first through channel connects the first inlet with the first outlet and the second through channel connects the second inlet with the second outlet, the valve piston blocks the end ports of the first flushing channel, and the first and second cross-over channels connect the second and third flushing channels to allow flow of material therein from the second inlet. In the second position, the first cross-over channel connects the first inlet with the second outlet and the second cross-over channel connects the second inlet with the first outlet, the valve piston blocks the end ports of the first flushing channel, and the first and second through channels connect the first and third flushing channels to allow flow of material therein from the first inlet. | 03-29-2012 |
20140138472 | ROLL STAND ASSEMBLY - 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. | 05-22-2014 |
20140166846 | EXTRUSION ROLL WITH SELECTABLE SKEW CAPABILITY - 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. | 06-19-2014 |
