Abstract

937,392. Feeding webs. SVENSKA FLAKTFABRIKEN A.B. Feb. 15, 1962 [Feb. 18, 1961], No. 5907/62. Class 100 (1). [Also in Group XIII] A device functioning as a turning roll for web-shaped material, and used in a paper-drying plant, Fig. 1, comprises an air distribution duct, as shown in Figs. 2 and 3, wherein air supplied under pressure, between the curved portion of the duct and the web passing thereover, through perforations 9, is maintained by two air curtains directed obliquely against the web from longitudinal slots 10. In the drying plant, Fig. 1, the drying medium is supplied by a plurality of blowing boxes 3 disposed between the web runs, and is blown against the web in the form of fine jets through the perforated walls of the boxes facing the web, the jets both supporting the web and advancing it.
