Abstract

1302049 Coating fibres by extrusion LIQUID NITROGEN PROCESSING CORP 15 June 1970 [17 June 1969] 9208/72 Divided out of 1302048 Heading B5A [Also in Division C3] Glass fibre reinforced injection moulding pellets, comprising 61 to 90% by weight of glass fibre, are cut from continuous glass roving coated by extrusion with molten thermoplastics containing a dispersion of further glass fibre. The pellet size, thermoplastics, rovings, and extrusion apparatus are as described in the parent Specification, and various examples ara given relating to glass fibre filled pellets of polystyrene, nylon, and polypropylene, containing the further glass fibre.
