Abstract
An apparatus ( ) and method for supporting a web ( ) of paper being transferred through a region ( ) from the surface ( ) of one moving component ( ) of a papermachine ( ) to the surface ( ) of a subsequent moving component ( ) of the papermachine utilizes an air-permeable sheet ( ) and a blowbox ( ) or Coanda air knives ( ) supported adjacent the air-permeable sheet. The sheet is supportable in a stationary condition across so as to span at least a portion of the papermachine region through which the moving web of paper is transferred and adjacent one side ( ) of the web, and the blowbox or Coanda air knives are used to move air away from the side ( ) of the air-permeable sheet opposite the web so that as the web is moved through the papermachine region, the web is biased by atmospheric air pressure into contact with the air-permeable sheet and moves in sliding engagement therealong.
