ABSTRACT:
An apparatus and method for cutting tubular band stock to produce an elastic band and unbonding the abutting edges of the band is disclosed. The apparatus includes a guillotine-type movable blade which cuts transversely across the tubular stock and band engaging surface proximate the blade which is formed to engage the cut band and shift opposite sides of the stock in a direction along the cut to break any bonds formed during the cutting process. The shifting apparatus is provided by a pair of fingers which engage one side of the band and cooperate with an arcuate surface engaging the opposite side of the band to shift two portions of the band next to the ends thereof toward the middle of the band and thereby effect breaking of the bonds. A reversible blade and reversible shear plate, as well as a lubricating structure and assembly for adjusting the band with which is cut also are disclosed.
