摘要

An apparatus (10) and a method are provided for producing a tubular product from reinforced resin material. The apparatus includes a mandrel (12) comprising a series of endless conveyors (16) that are radially arranged about and radially displaceable with respect to the centerline (C) of the mandrel. The series of endless conveyors diverge from that centerline from a first end (42) to a second end (44) to the conveyors. A shifter mechanism (50) is provided to radially shift the series of endless conveyors toward or away from the centerline as required to produce the tapered tubular product.
