ABSTRACT:
A method and apparatus for manufacturing a bat having an exterior and a hollow interior. The method consists of successive steps of placing a first layer of filament onto a rotating mandrel while simultaneously applying resin to the first layer; winding additional layers of filament around the first layer without resin; and vacuum transfer molding additional resin onto the filament layers so that the additional resin impregnates these layers. The apparatus consists of a mandrel; a mandrel holder allowing rotation of the mandrel; a resin applicator adjacent the mandrel of the same length as the mandrel; a filament winder for winding filament onto the mandrel; and a vacuum transfer molding apparatus. A bat made by this method is also disclosed. The present invention also relates to a resin bath to apply resin to a line of filament.
