<p>1,157,352. Cutting glass sheets. ASAHI GLASS CO. Ltd. 25 Aug., 1966 [27 Aug., 1965; 2 Nov., 1965], No. 38089/66. Heading C1M. Flaws are marked manually at 3 and the marks detected photo-electrically at 4. This information and that from a speed sensor 13 are fed into a computer 16 into which a cutting list has previously been fed. This controls transverse cutter A and a series of longitudinal cutters B through a time delay circuit. This circuit imposes a delay to permit transit of the sheet to the location of the cutters and this delay may be changed if a reserve cutter (not shown) is " used when the main cutter is inoperable. A further delay is imposed on each longitudinal cutter to compensate for its individual operating characteristic and as disclosed one of six preset delays can be matched to the cutter. The longitudinal cutters are solenoid operated through an "AND" gate fed by the delay network and by the computer instruction.</p> |
