Abstract

1443679 Preventing set-off TEC SYSTEMS Inc 27 Sept 1974 [4 Oct 1973] 42175/74 Heading B6C [Also in Division F4] An elongate tubular air bar B for a web dryer comprises two longitudinally extending supply slots 60, 61 and intermediate the slots 60, 61 an exhaust passage means 66 communicating with an air exhaust chamber 70 within the air bar B, the slots 60, 61 in use providing an air flow of which a part has a component of flow towards the air exhaust passage means. This is achieved by providing a Coanda plate 63 to form an edge of each of the slots 60, 61, the other edge being formed by the side wall 78 of the air bar. The chamber 70 is formed by a plate 74 co-operating with the Coanda plate 63. The exhausted air passes to the ends of the chamber 70. In a modification air is exhausted through tubular members extending from the chamber to the base of the air bar (Figs. 6, 7, not shown). A plurality of air bars are used in a drying apparatus as disclosed in Specification No.1.368,582.
