This concerns a screw pump for the extrusion of plastic materials, which is extremely compact and so it can be inserted in-line in a plastic material filtration system, encapsulating within it a duct parallel to the axis of the screw.

The invention relates to a method and a processing plant (1) for plastic material, for the recycling thereof. To this end, the processing plant (1) comprises a feed device (4), a processing unit (2) having a comminuting device (5) and a conveying device (6) adjoining the comminuting device (5), and an extrusion device (3) having an extruder screw (21). During its conveying movement along a first conveying section (9) toward a transfer region (8) by means of the conveying device (6), the comminuted plastic material is heated to a transfer temperature with a mean temperature value, which falls into the range of the softening temperature of the plastic material. In the transfer region (8), the comminuted plastic material is transferred to the extrusion device (3).

A production line for manufacturing extruded plates, comprises a conveyor for conveying a semifinished product, an edge cutting device for cutting off an edge area of the semifinished product to present a plate-shaped endless base profile, and a separating device for separating individual plates from the endless base profile. A distance (D) between the separating device and the edge cutting device in the conveying direction is dimensioned such that, between an average temperature T.sub.1 of the semifinished product during cutting of the edge area in the edge cutting device and an average temperature T.sub.2 of the endless base profile during separation, there is a temperature difference T.sub.1−T.sub.2 of 2 K≤T.sub.1−T.sub.2≤15 K. Due to distance (D) within an optimum temperature range, further processing of the cut off edge areas is essentially neutral in terms of installation space.
