Abstract
477,042. Feeding webs; printing- machines. VOMAG-BETRIEBS-AKT.-GES. June 19, 1936, No. 17136. Convention date, June 20, 1935. [Classes 100 (i) and 100 (ii)] A fixed hollow web guiding bar, e.g. a web turning bar for a printing-machine, to which a gaseous pressure medium is supplied, is provided with discharge orifices for the pressure medium in the form of slots extending in the direction of travel of the web and opening into recesses in the surface of the bar so that the web is held in a floating condition as it passes round the bar. A hollow cylindrical bar 1, Figs. 1 and 2, secured to the machine frame by brackets 8, is provided with rows of slots 2 opening into recesses 3, the slots and recesses extending in the direction of travel of the web 4. The recesses merge into the surface of the bar at the ends toward which the web approaches and have substantially radial ends 12 at the other ends. The slots 2 are shaped so that the air &c. under pressure emerges in a substantially tangential direction and a spin may be imparted to the air by providing one or more helical guides within the bar. The margins of the web may be guided by fillets 6 and, when a narrow web is being guided, those slots 2 not covered by the web may be closed by an internal or external sleeve. A loiigitudinal strip may also be secured to the bar where the web leaves the bar. When used for guiding freshly printed webs, the pressure fluid may be heated to dry the ink and the drying may be assisted by the provision of a suction device 9.
