Abstract
<PICT:0577316/IV/1> A plurality of layers of fibrous or woven sheet material impregnated with thermoplastic or thermohardenable mouldable material are formed into a tube 1, and the tube is moulded at raised temperature and pressure into a consolidated product, a head portion 3 comprising a mouldable thermoplastic or thermohardenable material being simultaneously moulded integrally therewith. The head portion may be made of (a) rolled impregnated fabric; as shown, the head is initially separate from the tube, but may be integral therewith; (b) a wad consisting of a number of superimposed fabric discs impregnated with partly-cured resin; or (c) solid unlaminated mouldable material, e.g. a moulding powder. Prior to the final heating under pressure, the impregnated fabric may be treated to partly cure the resin. A waterproofing varnish may be applied to the edge of the tube 1 and the rim of the head portion 3, before, during or after making. If desired, the whole case may be varnished. After the case has been loaded, it may be closed by (a) a flat disc either sprung into a groove machined in the interior of the tubular portion or secured by pegs, the closure being sealed by adhesive or varnished: this disc may be a resin-impregnated laminated-fabric product; (b) a flanged disc, the flange facing inwards or outwards and being secured as by an adhesive or acid-hardening cement of the phenol formaldehyde type; the plane surface may be slightly domed inwardly. The mould base has a central pin 7 which forms an aperture to accommodate the ignition means. A recess 9 in the mould wall forms a rim on the cartridge case head.
