Abstract

1,207,856. Fibre-glass tubes. WERKSPOOR N.V. 12 Oct., 1967 [12 Oct., 1966], No. 46661/67. Heading F2P. A method of producing a hollow member by winding layers of glass-fibre strip 4 around a former 1 and impregnating these layers, either during or after the winding operation, with synthetic resin, particularly polyester resin, is characterized in that the strip is wound, with prestressing, around the former and chopped-up glass fibre 16 is fed into the angle between the wound body of the glass fibre strip 4 already on the former and the strip portion being fed to the former. The strip 4, fed from a roll 3, passes between rollers 6-11 in a bath containing, e.g. polyester resin, and is wound on to the former 1 with a small pitch which may be reversed for successive layers. After one layer has been wound on to the former 1 chopped-up glass fibre 16 is fed through a nozzle 17 into the angle between the strip 4 and the layer of strip already wound. Cutters 18 rotate in the nozzle which is supplied with compressed air. The strip 16 may be fed to the underside of the former 1 in which case the chopped-up fibre 16 can be scattered on to the strip. The strip may be impregnated with synthetic resin by a sprayer as it is wound.
