Abstract (en)
[origin: US5899405A] The winding machine of the invention includes two parallel wound web roll support rollers which are spaced apart and on which the roll being wound is supported. The gap between the support rollers and below the supported wound roll is to be pressurized. A pressure chamber is defined by the support rollers, the wound roll above, and from below by a cross member which bridges over the distance between the support rollers and closes the bottom of the gap. End walls close the ends of the chamber. The cross member is movable between a sealing position where it is in contact with, or at least is sealed with, the two support rollers and bridges the gap between them to an open position where it opens the gap between the support rollers. The cross member is movable either down out of the gap, laterally out of the gap, or a combination of both, by reciprocating swinging, or oblique movement, and the like. The cross member has at least one passage which connects the pressure chamber with a source of compressed air through an intermediate conduit. An elongate transverse distributing pipe arranged at a distance from the cross member has a pressure connection through the conduit leading to the cross member.
