Abstract

1,181,468. Making files and rasps; rolling. PETER STUBS Ltd. 28 Nov., 1968, No. 56421/68. Headings B3A, B3L and B3M. A file is made by forming an upcut 1-1, Fig. 5, by means of a file cutting machine and superimposing an overcut 2<SP>1</SP>-2<SP>1</SP> by rolling, the direction of the overcut being that associated with the "row-off", the line formed along the length of the file by the stagger of the teeth of the file. The ridges of the roller F, Fig. 7, used for the rolling preferably have an acute angle a which affords good penetration of the upcut and gives a maximal length of cutting edge (D<SP>2</SP>), Fig. 8 (not shown).
