Title: Extruding cable or pipe sheath - through head which subdivides material into many individually heated streams
Inventor: WERWITZKE LOTHAR
IPC: B29C48/06
Filed: 1972-07-13
Abstract: A method of making long extrusions, e.g. sheathing for electrical cables, pipes or solid cores, utilises an extruder head in which additional heat is imported to the material to raise it to the cross-linking or vulcanising temperature before extrusion. The flow in the head is subdivided into many thin streams, which are each individually raised to this temp; then they are all-re-combined before leaving the extruder head. The small streams are pref. concentric annuli, radial webs or longitudinal strips.

Title: Laminated (profiled) mouldings prodn - by hot pressing lay-up of flexible foam and thermosetting resin pre-impregnate
Inventor: TAPPE MICHAEL
Filed: 1973-04-25
Abstract: Mouldings of >=2 layers, >=1 of which consists of a flexible foam (I), are produced, by bonding, by laying up mouldable layers contg. a curable, thermosetting resin (II) with a (I) layer and hot pressing. The prods. can be used for insulation against heat, cold and noise and for upholstery in the furniture and automobile industries. The process is simple and gives parts of improved quality. Pressing and moulding of the individual layers are carried out simultaneously. (I) is an open-cell (polyurethane) foam, whilst the layer contg. (II) is polyester-impregnated glass fibre mat and a precondensed melamine or phenolic resin preimpregnate. Pressing is regulated, according to the (II) flow, so that at least part of the thickness of the (I) layer is not filled by the resin.
