Abstract:
An apparatus for supporting a web of paper moving through a region of a papermachine in which the moving web of paper is transferred from the surface of one component of the papermachine to the surface of a subsequent component of the papermachine, the apparatus comprising:an air-permeable sheet supportable in a stationary condition across at least a portion of a papermachine region through which a moving web of paper is transferred from one component of the papermachine to a subsequent component of the papermachine and so that as the web is moved through the papermachine region, the web moves along one side of the air-permeable sheet; and means associated with the air-permeable sheet for creating a zone of sub-atmospheric pressure on the side of the air-permeable sheet opposite the web of paper so that as the web is moved through the papermachine region, the web is biased into contact with the air-permeable sheet and moves in sliding engagement therealong.
