Abstract
Stranding apparatus for fabricating open-weave structures includes a base frame supporting a pair of spaced apart plates, both of which plates includes a plurality of movable pins on which resin impregnated, continuous filament strands are placed. The pins retract into the plates after the resin has cured to allow the stranded product to be removed from the frame. The apparatus rotates about a central axis to provide a plurality of stations at which a specific process or step is accomplished.
Claims15
Stranding apparatus comprising, in combination:
- frame means, including a first support element and a second support element;
- first plate means rotatably secured to the first support element;
- second plate means rotatably secured to the second support element and spaced apart from the first plate means;
- a shaft secured to the frame means for locking together the first plate means and the second plate means for joint rotary movement relative to the first and second support element, and movable vertically for unlocking the first plate means and the second plate means;
- and
- pin means secured to the first and second plate means and movable between an outer position to receive strands and a retracted position for removal of the strands.
Stranding apparatus for stranding a plurality of articles of resin impregnated strands, comprising, in combination:
- rotatable turntable means;
- frame means disposed on the turntable means, including
- first stranding frame means, and
- second stranding frame means spaced apart from the first stranding frame means;
- plate means, including
- a first plate and a second plate spaced apart from each other and secured to the first stranding frame means, and
- a third plate and a fourth plate spaced apart from each other and secured to the second stranding frame means;
- shaft means secured to the frame means, including
- a first locking shaft extending between the first and second plates for locking the first and second plates together and movable to unlock the first and second plates and to raise the first plate relative to the second plate, and
- a second locking shaft extending between the third and fourth plates for locking the third and fourth plates together and movable to unlock the third and fourth plates and to raise the third plate relative to the fourth plate;
- pin means, including a plurality of pins extending outwardly from the plate means and movable between an extended position outwardly from the plate means for receiving strands and a retracted position for removing the strands from the plate means;
- curing means disposed adjacent the turntable means for curing the resin impregnated in the strands disposed on the plurality of pins;
- and
- means for rotating the turntable means from a first position where the first stranding frame means is stranded to a second position where the first stranding frame means is disposed adjacent the curing means for curing the resin impregnated strands on the first stranding frame means, and the second stranding frame means is at the first position to be stranded.
