Abstract

342,871. Printing-machines. DAUSMANN, C. F., 1019, South Oak Park Avenue, Oak Park, Illinois, U.S.A. Jan. 14, 1930, No. 1354. Convention date, Jan. 21, 1929. [Class 100 (ii).] Rotary machines; drying-apparatus.-In a method of drying ink impressions in a rotary web press having vertically spaced printing-couples, the moving web is supported between the printing- couples against deflection from its plane of movement and subjected on the printed surface, over the supported area, to the pressure of unheated air delivered at low pressure at each of a plurality of spaced points between the printing-couples and in close proximity to the printed surface and acting directly upon the ink to cause the surplus fluid ink to impregnate the web fibres. The Figure shows an arrangement of printing-couples in two sets for printing upon the opposite sides of the web in four colours in one movement of the web through the press. An endless travelling blanket 7, surfaced with rubber on its outer side, is movable over a rigid metal support 8, and engages with the paper web W for substantially the entire distance between the upper and lower printing-couples 5, 6; 5<1>, 6<1>. At vertically spaced points between the upper and lower printing-couples and closely adjacent to the web, a number of transversely positioned tubes 9 are situated. The interior of each of these tubes is centrally divided by a plug, and the wall of each tube is provided with orifices of varying diameter. Air at room temperature and low pressure is supplied to the tubes by means of a blower. A body of frusto-conical shape fitted to the outlet of the blower is provided with tapering pockets terminating in nozzles which are connected by flexible tubes 23 to the jet tubes 9. A spring- pressed valve may be fitted in the top of the body to control the pressure of the air delivered. Specification 228,320, [Class 100 (ii), Printing processes &c.], is referred to.
