ABSTRACT:
An apparatus for producing profiles or webs such as tread strips for vehicle tires from suitable materials, comprises, in sequence, a screw extruder, an extrusion head and a rotatable roller. The roller is disposed in such a manner that the screw can be removed over the roller without interfering with the roller. To achieve this, the head comprises an upper and a lower portion, the upper portion being pivotable so that it can be moved out of the path of the screw when this latter is removed. The pivot points for the upper portion of the head are on lateral walls. The upper portion of the head is also lockable in its working position, the head portion facing the roller being spaced from the surface of the roller.
