ABSTRACT:
Extruder and twin roller calendering plant for producing films or sheets of synthetic plastics or rubber material comprising a pair of calendering rollers mounted in a calender frame and an extruder nozzle head directed into the gap between the pair of calendering rollers, the calender frame being pivotally mounted such that it can be pivoted away from the extruder nozzle head to allow ready access to the extruder nozzle head. The calender frame may be pivotally mounted on the nozzle head and a counter balance weight and/or the drive motor for rollers can be mounted on an opposite side of the pivot to the rollers thereby to counter balance the weight of the rollers.
