Abstract

1,165,093. Selective signalling. ATELIERS HEUZE, MALEVEZ & SIMON REUNIS S.A. 15 Feb., 1968 [13 June, 1967]. No. 7374/68. Heading G4H. The co-ordinates of defects in a sheet of material e.g. glass, are determined by a row of photo-cells transverse to the direction of travel of the sheet, one of the photo-cells being energized or de-energized on detection of a reflective or opaque piece of gummed paper stuck on to the sheet at each defect, and means for measuring increments of movement of the sheet between detection of the leading edge of the sheet and detection of each defect. The co-ordinates may be supplied to a computer for selecting a cutting programme involving the least amount of wastage.
