摘要： Fibrous network structures are produced within liquid polymer resins by passing the fibre-containing resin along a channel having a plurality of sets of flow modifying elements which establish a regulated succession of velocity profiles for the principal flow direction and the two directions perpendicular thereto. The individual velocity profiles persist over distances which are small compared to the channel dimension over which they are established and are such that there is substantially no net deviation from the principal flow direction. The velocity profiles superimpose on each other to cause rotation and sliding of the fibres so that a coherent network structure is built up which persists through extrusion dies or moulds into the solid state. By means of a large number of touches per fibre the structures thereby established confer efficient mechanical reinforcing properties and enhanced thermal properties on the polymer composition.

摘要： 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.

摘要： 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).
