Kind Code:

Abstract:
A plurality of knives are supported on and clamped to a rotary cutter head by a plurality of similarly formed wedges aligned in contiguous face-to-face relationship to define two endless, spaced apart arrays for clamping opposite end portions of the knives. Each wedge defines within one of its faces a recess for receiving an end portion of a knife, and further defines on its opposite face a keyed surface that interengages within the recess of an adjacent wedge to abut against the received end portion of an adjacent knife. A band member encircles each array for clamping together the wedges of each array. The clamped knives are thereby made more rigid and more resistant to buckling and twisting due to compressive stresses exerted against the cutting edges by yarn or tow being wrapped around the cutter head in contact with the knives prior to cutting; and in one embodiment are the sole support between the upper and lower array of wedges on the cutter head, and in another embodiment may be tensioned to resist buckling due to still greater compressive stresses or significantly large yarns or tows.
