PCT No. PCT/GB89/00260 Sec. 371 Date Aug. 22, 1990 Sec. 102(e) Date Aug. 22, 1990 PCT Filed Mar. 13, 1989 PCT Pub. No. WO89/08546 PCT Pub. Date Sep. 21, 1989.A method for the manufacture of a reinforced tubular article involves forming at a first work station (14) a first flexible reinforced tubular structure in which at least one reinforcing element extends generally circumferentially, e.g. helically. The first tubular structure is cut transversely to form cut edges (17, 18) and then transported, typically as a flat sheet, by means of a carrier (15) to a second work station (25, 26) at which it is formed into a second reinforced tubular structure in which the cut edges (17, 18) extend generally circumferentially. Thus there is provided, by the method of the invention, a second reinforced tubular structure in which the reinforcing element(s) of the first tubular structure is or are re-orientated to extend in a substantially longitudinal direction of the tubular structure. |
