ABSTRACT:
A segmented extruder device for extrusion along a longitudinal axis. The device has a plurality of segments enclosing a barrel aligned on the axis. The segments each include a pair of axially perpendicular end flanges for each segment. Each of the flanges have exposed sides and a central portion for housing an extruder barrel. The flanges have a plurality of straight line paths for fluid flow into and out of the flanges in a plane perpendicular to the axis. A port is provided to give access to each straight line path from at least one side of each flange. A housing portion is placed between each of the pair of flanges for housing the extruder barrel. The housing has a plurality of straight axial channels operably connecting the flanges to conduct fluid along the barrel from each of the straight line paths in one flange to a corresponding straight line path in the other flange. Finally, the device includes an inlet and an outlet for introducing fluid into and removing fluid from selective paths and channels.
