Patent ID: 7140987

Claim:
A method of making a laminated ball bat, said method comprising the steps of: providing a first laminated block, said first laminated block comprising a plurality of successively adjacent thin strips wherein adjacent thin strips are bonded together by a bonding agent; providing a second laminated block, said second laminated block comprising a plurality of successively adjacent thin strips wherein adjacent thin strips are bonded together by a bonding agent wherein the density of said second laminated block differs from the density of said first laminated block, and wherein the length of the second laminated block is shorter than the length of the first laminated block thereby creating a length delta; selecting the location of said second laminated block and a length delta value that provides for a laminated blank having a predefined weight distribution; bonding said first laminated block to said second laminated block to form at least part of a laminated blank that is composed of a plurality of bonded laminated blocks; subjecting said laminated blank to a pressure in a range of about 100 pounds per square inch to about 250 pounds per square inch; maintaining said laminated blank under pressure in said range until said laminated blank has cured thereby forming a cured laminated blank; and machining said cured laminated blank to form an elongated body disposed about a longitudinally extending axis, said body having an outer surface defined by the exterior outline of a bat, said body including a handle on one end and a barrel on the opposite end, said body including a label section connected between said handle and said barrel.
