ABSTRACT:
A system and method for turning up a web of paper moving in a tensioned condition across the surface of a rotating reel at the winder of a paper making machine from a first drum to a second drum utilizes a conduit for receiving air from a pressurized air source and having a discharge end through which pressurized air received from the source exits the conduit in an air stream. A stand supports the conduit adjacent the reel for movement between an operative position at which the discharge end is positioned adjacent an edge of the web and a non-operative, out-of-the-way position situated to one side of the reel. A cylinder assembly is connected between the conduit and the stand for moving the conduit between its operative and non-operative positions, and a solenoid valve is connected in-line with the conduit permitting a sudden stream of air to exit the discharge end upon actuation of the valve. When the conduit is positioned in its operative position and the air stream is directed toward an edge portion of the web, the air stream separates the edge portion along a path of separation so that the tension to which the web is exposed subsequently completes severance of the web from the formed path of separation to provide the web with a severed edge extending between the opposite side edges of the web, and so that the severed edge of the web is urged by the air stream toward the second drum for winding thereabout.
