Abstract
A wrapped core for a ski comprising a wood or foamed plastic longitudinally extending core having first longitudinal strands of material positioned on the top and or bottom surfaces of the core and second strands of fiber reinforcement braided thereover to surround the core and capture said first strands. Third longitudinally extending strands of fiber reinforcement are intertwined with said second braided strands. The method and apparatus for forming the wrapped ski core.
Claims50
A wrapped ski core comprising:
- a longitudinal core, and,
- a plurality of continuous strands of a first set of fibers helically surrounding said core said fibers braided snugly thereon, conforming to the surface of said core;
- said braided strands of the first set of fibers being biased at an angle with respect to the longitudinal dimension of said core.
A wrapped core for a ski comprising:
- a longitudinal core having a laterally narrowed waist portion;
- a plurality of first continuous strands of fiber braided thereon and conforming to the surface dimensions of said core;
- said braided strands being helically wrapped about said core and biased at angles with respect to the longitudinal dimension of said core;
- a plurality of second strands of fiber being interwoven with said first strands and aligned with the longitudinal dimension of said core.
A method of wrapping a ski core comprising the steps of:
- moving a ski core longitudinally along a path through a braiding machine;
- braiding continuous strands of a first set of reinforcing fibers about said core from the leading end of said core to the trailing end such that said strands are angularly oriented with respect to the length of said core;
- and,
- maintaining tension on said strands during braiding.
In a ski having a longitudinally extending body portion and an upturned tip portion, an improved reinforcing fiber wrapped internal core, comprising:
- a plurality of continuous strands of a first set of fibers braided upon said internal core and conforming snugly to the surface thereof, said strands of the first set of fibers lying at angles to the length of said core.
