Abstract
A knife adjustment system including a normally non-rotatable quill threadably attached to a hub outwardly extending from the face of an extrusion die at a point proximal said face in order to insure that the operating temperatures of such quill and hub at the connection location are generally equal. Adjustment means for threadably rotating the quill with respect to the hub so as to in turn adjust the spacing of cutter knives with regard to the die face in the form of a planetary gear system located at that end of the hub distal from the die face is further included. The knives are fixed to a knife carrier and in turn supported for rotation about the quill.
