ABSTRACT:
Apparatus for manufacturing bolsters used to form the core for fabric windings includes apparatus to apply glue to specific areas of pre-sized cardboard cards, crimp the cards at specific locations to produce edges for the finished product, fold the crimped card, and compress the card to insure proper adhesion of the edges to the surfaces they contact, to form the finished bolster. The bolsters are produced by a method of passing a pre-sized cardboard card through the steps of gluing, crimping, folding and compressing, to provide a finished bolster of any predetermined length. A bolster is produced from a cardboard card of sufficient stiffness to provide for a substantially hollow construction, other than for a central stiffening spline used to determine the height of the bolster and provide rigidity to the bolster.
