Abstract

1384772 Polishing CURRIE & RICHARDS INDUSTRIES Ltd 28 Jan 1972 4219/72 Heading B3D Means for polishing an edge region of a guillotine blade 20, e.g. for paper cutting includes a flat surface 2 for abutting the blade 20 and a polishing member for working on the blade 20 adjacent its cutting edge. A plate 3, adjustable on the surface 2, e.g. by means of a screw 4 bears rollers 6 for location against a rear edge of the blade 20, and the polishing member may comprise a cylinder 8 bearing a buffing pad 12, a series of coaxial flexible discs (not shown) or abrasive belt means (not shown), drive from a motor 7 being transmitted through a belt (15), Fig. 2 (not shown). Abrasive in a fluid medium may be applied to the pad 12, and a surface finish of 1 micron R.M.S. may be achieved on a strip adjacent the blade edge of about 0À020 inch in width.
