ABSTRACT:
Quickly adjustable, magnetically detachable spacing means for rotary slitting or shearing knives which permit the knives and spacing means to be loosened axially by the arbor nut and remain near their working positions on their supporting arbor while the axial spacing of any pair or pairs of knives is being changed. The spacing means may comprise one or more spacers of magnetic material and of conventional annular form and axial length having close sliding fit on the arbor. The spacer nearest a knife may carry permanent magnets with their poles near the axial face of the spacer proximate the knife to which semi-annular magnetic shims have been magnetically and detachably secured on diametrically opposite sides of the arbor. Substitution of a selected thicker or thinner pair of similar shims will increase or decrease the spacing of the knives as may be desired as by sliding the shims radially on the axial face of the spacer and over the poles of the magnets. Magnest may be secured in both axial end faces of spacers. Shims may be held magnetically between spacers. Spacers like shims, may take semi-annular form being split diametrically, each half spacer having no more than 180.degree. of circumferential length and fit the arbor snugly. The semi-annular spacers preferably have magnets at both axial ends to afford secure magnetic engagement with magnetic parts at one or both ends.
