Abstract

1473040 Duplicators G RITZERFELD 28 July 1975 [14 Aug 1974] 31445/75 Heading B6C In a rotary duplicator a sheet moistening device comprises a pressurizable container 4 which is constantly fed liquid 5 by pump 6 and intermittently feeds the liquid 5 to a pad 1 in synchronism with rotation of the printing drum. Relief valve 11 on spring 13 prevents excess pressure and feed to the pad 1 is controlled by a one-way valve 3 which is only open when switch 20 is operated and this occurs once every rotation of the printing drum.
