ABSTRACT:
A wrist support (10) and method for constructing the wrist support is described. The wrist support includes a base (12) with a cushion layer (14) mounted on the top surface (12A) and an outer covering (16) surrounding the base and cushion layer. The bottom surface (12B) of the base has an adhesive (13) which is protected by a release paper (15). The release paper is removed in order to secure the ends (16A) of the outer covering to the base. The wrist support is constructed from a sheet of base material (36) and a sheet of cushion material (38) which are cut into a wrist support preform (26) in a mold (20). The sheets are inserted between a first half (22) and a second half (32) of the mold with the base adjacent the second half of the mold. The first half of the mold is then moved downward into contact with the second half which causes the second half to also move downward and which enables the plunger (34) of the second half to extend into the indentation (24) of the first half. As the plunger enters the indentation the cutting edges (34C) of the sidewalls (34A) of the plunger cut the sheets of material into the shape of the wrist support. The first and second halves of the mold continue to move downward causing the plunger to compress the cut base and cut cushion layer against the top (24B) of the indentation with the edges (12C) of the base adjacent the curved portion (24C) of the indentation.
