Extrusionsverfahren für zwei oder mehreren Materialien

摘要

A method of making ornamented elongate members, for example for picture frames, comprises the steps of extruding a first material (4) and cooling it so that it is substantially solid, extruding a second material (6) along a surface of the first material (4), which is arranged to undergo a change enabling a firm bond to be formed between the materials, shaping the second material (6) to produce surface ornamentation (9) and cooling the first and second materials. This provides an inexpensive and quick way of producing ornamented members.
