摘要 To accomplish a web transfer, which in reliability is comparable to the one obtained with a closed draw, in any operating environment, but especially where it is desirable to transfer a fast running tissue web ( 4 ) from the drying section of a tissue machine, e.g., a Yankee dryer ( 2 ), to a reel-up ( 3 ), a web support device ( 10 ) extends across the width of the web ( 4 ) and along a predetermined run of the web support device has a support surface ( 11 ) formed by a series of plate member assemblies ( 23 ) having means for creating a flow of air in the direction of the web run. Between the web ( 4 ) and the support surface ( 11 ) the flow of air forms an air layer ( 15 ) of reduced static pressure, so as to stabilize the web ( 4 ) against flutter. The predetermined run may extend through a calender ( 7 ) and past scanner equipment ( 8 ). Pneumatic tail threading capabilities may be included.
