Abstract
976,149. Printing apparatus. INTERNATIONAL BUSINESS MACHINES COR. PORATION. Dec. 14, 1961 [Dec. 27, 1960], No. 44806/61. Heading B6C. A stencil 10 is produced by the impact of a type slug 13 on a stencil assembly comprising two sheets of card stock 14 having central apertures 15, two sheets 16, 17 of plastic material defining an envelope within said apertures, and, within said envelope, an inkfilled cellular plastic sheet 18 having embedded therein a plurality of small glass beads. The localized pressure of the slug 13 against the sheet 17 causes the beads 19 to cut the thinner and weaker plastic sheet 16 which is in contact with a roller 11. Owing to capillary action, however, ink does not flow out of the cuts 22 in the sheet 16 until it is forced out during printing on a sheet 21 by a pressure roller 20. The glass beads may be replaced by a porous sheet of sandpaper, Fig. 2 (not shown), or the glass beads may be dispensed with and the roller 11 replaced by one having a roughened surface which cuts the plastic sheet, Fig. 3 (not shown), Only one card stock 14 may be provided with a central aperture.
