Abstract

1,251,366. Cutting and grinding sheet glass. PERMAGLASS Inc. 15 Nov., 1968 [5 Feb., 1968], No. 54203/69. Divided out of 1,251,364. Heading C1M. In cutting and grinding a sheet of glass in accordance with a pattern, the sheet and pattern are rotated in unison, the sheet being rotated relative to the cutting or grinding means, and the speed of rotation of the sheet is controlled to maintain substantially constant the tangential velocity between the cutting or grinding means and the edge of the sheet by measuring any deviation from a predetermined value of the linear velocity of the edge of the pattern and correcting the speed of rotation of the sheet in correlation therewith. The apparatus forms part of a cutting and grinding machine as disclosed in Specifications 1,251,364, 1,251,365, 1,251,367, 1,251,368, 1,251,369 and 1,251,370 are also referred to.
