Claim 10:
11. A swivel knife holder assembly for a reciprocating knife, the holder assembly comprising:
a shell defining an interior with a distal opening and a proximal opening, the shell having a flange segmenting the interior into a distal pocket and a proximal pocket;
a shoulder screw extending from the distal pocket to the proximal pocket along an axis;
a first bobbin assembly mounted on the shoulder screw adjacent a head of the shoulder screw in the distal pocket;
a second bobbin assembly mounted on the shoulder screw in the proximal pocket,
wherein each bobbin assembly includes a thrust bearing/spacer assembly for rotating about the axis within the respective pocket;
a shock-absorbing member for absorbing axial load and axial tolerances in at least one of the pockets;
a stem threadably coupled to a threaded end of the shoulder screw to enclose the proximal pocket and apply axial compression to the shock-absorbing member, wherein the stem has a mounting surface for engaging a reciprocating axial drive mechanism; and
a core mounted in the distal pocket for enclosing the distal pocket and holding the knife,
wherein the shell engages a rotating drive mechanism to swivel the core about the axis and, in turn, the knife to a desired orientation.
