Abstract
The swivel knife holder assembly includes a shoulder screw defining an axis, and having a proximal threaded end and a distal head, and mounted on the shoulder screw is a bobbin assembly. The swivel knife holder assembly also includes a shell defining an interior, and having a distal opening and a proximal opening. A core is secured in the interior and is coupled to a knife for cutting fabric material. The proximal opening of the shell is defined by a flange and houses the shoulder screw therein. Threadably coupled to the proximal threaded end of the shoulder screw is a stem. The stem secures the bobbin assembly within the shell and also includes a mounting surface for engaging a reciprocating drive mechanism.
