ABSTRACT:
A cutter for severing work pieces chained together and for removing thread in close proximity to the work piece, such as on leading and trailing edges. The cutter of the invention permits close proximity of adjacent work pieces during the process of sewing but is still able to cut and remove free thread without necessitating undue slack as normally required with a shear type cutter (unlike a guillotine type cutter), or similarly can remove trailing thread between the work piece and the sewing machine.
