    • Pronounced surface roughness or undulations will sometimes be obtained on the unsized surface of plastic extruded hollow profiles. Particularly is this so for plastic resins containing fibres. In the invention smooth finishes are obtained on both external and internal surfaces of a hollow profile by passing the extruded resin first through or over a cooled sizing unit and then over or through a finishing unit in the form of a plug or a ring which will usually be heated. The heating will allow the asperities or the unsized surface to flow locally to conform to the plug or ring surface without disturbing the basic form of the pipe or tube wall. Subsequent cooling of the smoothed surface will be by heat loss to the interior of the pipe wall downstream of the finishing unit so that smoothed finishes are retained in the cooled pipe or tube.
    • 有时在塑料挤出中空型材的未表面上可以获得显着的表面粗糙度或起伏。 特别是对于含有纤维的塑料树脂。 在本发明中,通过使挤出的树脂首先通过冷却的施胶单元,然后通过塞子或环的形式的整理单元,然后通过挤出的树脂通常在 加热。 加热将允许粗糙或不平坦的表面局部流动以符合插塞或环表面,而不会干扰管或管壁的基本形式。 平滑表面的后续冷却将是通过热量损失到整理单元下游的管壁内部,使得平滑的表面处理被保留在冷却的管或管中。

    • A method of separating filaments (8) from a clump thereof in a liquid flow from each other comprises sub-dividing the flow across its lateral extent to pass through an array (4) of a plurality of filament separating channels (9) having a cross-section at least large enough to accommodate the cross-section of the clumps such that flow along the channels (9) imparts a shearing force to filaments (8) at the edge of the flow in the channel to separate these axially from each other and from filaments (8) at the centre of the clump. The liquid may be a polymer melt obtained by melting polymer granules containing lengths of yarn or tow and the method used to separate the individual filaments from the yarn or tow prior to forming a network structure from the filaments (8).
