Method for handling components of a sheet extrusion system
A method of handling components for a sheet extrusion system including the steps of: obtaining a carriage configured to support different components each making up a part of a sheet extrusion system; placing a first of the different components in a supported staging position on the carriage; and performing an operation on the first of the different components in the supported staging position to at least one of: a) transport the first of the different components; b) perform a maintenance step on the first of the different components; c) repair the first of the different components; or d) set the first of the different components up for installation. The method further includes the steps of: separating the first of the different components from the supported staging position on the carriage; and reconfiguring the carriage to maintain a second of the different components, that is different in configuration than the first of the different components, in a supported staging position on the carriage.
A method and apparatus for processing a formable material having at least first and second relatively repositionable units. The first unit has a sheet die, with the second unit having a rotary drum with a peripheral forming surface for receiving flowable material from the sheet die. The first and second units can be selectively changed between an operating relationship and a setup relationship, with the latter causing at least one space to be defined/enlarged and within which an operator can maneuver to gain access to a region of at least one of the first and second units. With the first and second units in the operating relationship, moldable sheets can be processed by causing the moldable sheets to be applied, and conformed, to the peripheral forming surface on the rotary drum.

An extruder assembly has a frame with upstream and downstream ends. A barrel assembly on the frame has a passage. At least one material advancing component resides at least partially within the passage and is configured to be turned around an operating axis to thereby cause material to be conveyed from a passage inlet to a passage outlet. A drive assembly turns the at least one material advancing component around its operating axis and has a motor on the frame situated so that at least a part of the motor is in lengthwise overlapping relationship with the barrel assembly. The drive assembly is configured to turn the one material advancing component around its operating axis at a speed of at least 300 rpm.

Die assembly and method of setting up an extrusion system utilizing the die assembly
A die assembly through which flowable material from a supply is controllably delivered to a processing assembly at which a sheet layer is formed. The die assembly has a main frame and a support assembly for the main frame. The support assembly includes components cooperating between the main frame and a base upon which the main frame is supported to allow controlled relative vertical movement between the main frame and base to thereby permit controlled alignment between the main frame and an upstream component that delivers flowable material from the supply to the die assembly.
