Abstract
An apparatus for making fiber reinforced plastic members. The apparatus employs a rotatable mandrel (18) and a winding head (16) with a unique arrangement by which to effect relative longitudinal movement between the winding head (16) and the mandrel (18). Either the winding head (16) or the mandrel (18) may be longitudinally fixed. The other of those members is mounted on a trolley (30) that can be reciprocated parallel to the longitudinal axis (42) of the mandrel (18). This reciprocation is effected by having a dog means (51) mounted on the trolley (30) that is movable between a first and second position. In the first position the dog means (51) engages a lug (50) on a drive means to move the trolley (30) in one direction, and in the second position the dog means (51) engages the lug (50) to move the trolley (30) in the opposite direction. Further means (71, 72) are provided to move the dog means (51) between said first and second positions and to provide an appropriate dwell when the movement of the trolley (30) is reversed, said dwell allowing reinforcing strands (35) to anchor and being timed precisely to index the successive wraps of the reinforcing strands (35) onto the mandrel (18).
