ABSTRACT:
Apparatus for producing sheets or foils of plastic or rubber mixtures includes a calender having two rollers rotatably supported by spaced calender stands with a gap between the rollers and an extruder having an extruder head with wide mouth for extruding a sheet of material into the roller gap of the calender. One part of the extruder head is fixed while another part is pivoted for movement relative to the fixed part by a cylinder-piston unit. The calender is stationary while the extruder is mounted by screws, providing vertical adjustment, on a base having wheels for horizontal movement of the extruder toward and away from the calender to vary the distance between the extruder mouth and the roller gap of the calender. The base of the extruder is coupled with the calender by a threaded spindle rotatable through a reducing drive by a reversible motor to move the extruder toward and away from the calender.
