ABSTRACT:
The disclosure relates to an apparatus for applying a polymeric covering to a workpiece such as a cylindrical workpiece (10). In order to apply smooth surfaced coating firmly bonded to the workpiece in a single operation the workpiece is rotated in a lathe about an axis (11) and a rubber applying head is traversed parallel to the axis along the workpiece. The head has a freely rotatable tapered feed roller (19) forming a nip with the workpiece to apply polymeric material to the workpiece, a main roller (23) adjacent the feed roller and also forming a nip with the workpiece to pressurise and render plastic the rubber coating applied by the feed roller to masticate and compound the layer, a pressure surface (24) adjacent the main roller and incorporating a retractable plough (25) to dig into the rubber coating and release any entrapped air and a finish roller (26) to apply the required surface finish to the rubber coating. All the rollers are so angled in relation to the direction of travel of the head and the axis of rotation of the workpiece that they rotate automatically by engagement with the rubber layer on the workpiece to act on the rubber layer as the head is traversed along the workpiece.
