Spiral wound laminate wood and method for construction

Abstract

A baseball bat or the like comprised of one or more continuous spiral wound layers of wood, cellulose, or other like material rolled in a spiral fashion from the center to the outermost surface. The cellulose or other material is bound to each subsequent layer with a thin layer of resin, glue, epoxy, or other binding material of adequate strength to hold the layers together for multiple impacts by a baseball or other object. This spiral wound composite roll, in its final configuration, is of comparable density, weight and balance to ash, maple or oak material commonly used in baseball bat construction. The composite roll can be machined to a shape consistent with the shape and balance of traditional baseball bats.

1 . A bat or other implement with a spiral wound laminate from the center core to the outer surface, the spiral would laminate tapering in length from the center core to the outer surface.  
   
   
       2 . The bat or other implement of  claim 1 , wherein the spiral wound laminate is constructed of a plurality of laminates of different thickness.  
   
   
       3 . A method of forming a bat or other implement, comprising: winding having cellulose or other thin material in one or more layers over a core to form a structure; and forcing the structure into a gradually tapered mold to create pressure on the wound material to eliminate air pockets and minimize voids.  
   
   
       4 . The method of  claim 3 , further comprising, winding additional cellulose or other thin material about the structure to form a second structure, forcing the second structure into a gradually tapered mold to create pressure on the wound material to eliminate air pockets and minimize voids.  
   
   
       5 . The method of  claim 3 , wherein the bond is created by heat, pressure, chemical or other curing processes using adhesive material.  
   
   
       6 . The method of  claim 3 , wherein a final shape of the structure is configured in the shape of a bat.  
   
   
       7 . The method of  claim 3 , wherein forcing comprises pushing, pulling or sucking the structure into the mold by mechanical, hydraulic, pneumatic, centripetal, or centrifugal forces.
