Patent number: 5203937Abstract: 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.Type: GrantFiled: August 22, 1990Date of Patent: April 20, 1993Assignee: Bridgestone/Firestone Inc.Inventor: Anthony G.
