Abstract
An improved archery bow limb fabricated by inserting a moldable slug having a plurality of longitudinally oriented resin impregnated glass fiber filaments into a bow limb profiling compression mold. The mold includes a female cavity mold and a male mold. The female mold having a raised portion defining a limb tip slot area so that when the mold is closed a depressed tip slot impression is formed in the slug. The raised portion may include peripherally thereabout, reinforcing filaments for strengthening the slot edge defined by said periphery. After the slug has been cured, the material remaining in the base of the depression is removed thereby providing a bow limb having a pair of forks for supporting an eccentric therebetween. The resulting bow limb being fabricated with a reduced amount of severed longitudinal filaments.
Claims12
A method of compression molding an archery compound bow limb comprising the steps of:
- (a) forming a moldable slug composed of a plurality of longitudinally oriented fiberglass filaments;
- (b) disposing said slug into a compression mold profiled for a bow limb, said mold including means at each end for forming a depression in the profiled limb defining a partial limb tip slot at each end thereof;
- (c) curing said slug;
- and,
- (d) removing the material remaining in the partial limb tip slots to thereby form limb tip slots at each end.
A fiber glass resin molded archery bow limb paddle having an area defining a partial limb tip slot, said partial limb tip slot area having a depression therein which defines the partial limb tip slot.
The method of fabricating an archery bow limb comprising the steps of:
- (a) compression molding a bow limb paddle having an area defining a bow limb tip, said area being of reduced thickness;
- (b) removing said paddle area of reduced thickness to thereby provide a limb tip fork.
