Abstract

596,693. Dandy rolls of papermaking machines. TROTMAN, W. E. K. Aug. 29, 1945, No. 22248. [CLass 96] A watermark effect is produced by a rotating roll 10 formed with closely-spaced narrow openings 12 in its periphery, whereby pulp 14 on the wire-cloth 17 of a paper-making machine is made to have projections 16 which may be partly or wholly flattened out during calendering and pressing to form a rough-surfaced or smooth paper. Water may pass into the roll through the openings 12. The roll is positioned where the pulp has less than 95 per cent of water.
