Method and an installation for winding a pre-impregnated fabric strip onto a sloping surface
A method of winding a pre-impregnated fabric strip onto a sloping surface includes a step of deforming the pre-impregnated fabric strip by applying differing traction forces to the pre-impregnated fabric strip, the traction forces being directed in a longitudinal direction of the strip, the values of the applied traction forces differing across the transverse direction of the strip. The differing traction forces are applied by tensioning the pre-impregnated fabric strip between firstly a pair of brake rollers and secondly a traction device present downstream from the pair of brake rollers, the traction device driving the pre-impregnated fabric strip at speeds that differ across the transverse direction of the strip. The method further includes winding the deformed strip onto a surface of revolution of winding tooling including at least one portion that forms a nonzero angle with the axis of revolution of the surface of revolution.

Method for winding a cable onto a cable reel
A method for winding a cable (12) onto a cable reel (22) includes providing a cable reel (22) having a drum (24) arranged between two end flanges (28, 30). The drum (24) has a longitudinal axis (26), and the cable is placed (12) on the drum (24) to form a plurality of continuous helical windings (32) on the drum (24). Consecutive windings (32) are directly adjacent to each other, where main bending axes (34) of the continuous helical windings (32) and the longitudinal axis (26) of the drum (24) enclose an offset angle () greater than zero.
