WOUND ROLL SUPPORT IN A WEB WINDING MACHINE |
摘要 |
A winding machine for a continuous web includes at least two support rollers defining a bed for the wound web. At least one roller has a rotatable, perforated roller shell. A stationary pressure box disposed inside the roller shell which is opened toward the inner surface of the perforated shell and is connectable to a source of pressure air. A further longitudinally extending packing closes the bottom of the gap between the first and second rollers. Longitudinal packings at the pressure box define a pressure zone extending approximately from the further packing to the place where the round roll lies on the one support roller. A suction zone is defined at the support roller upstream in the direction of roll shell rotation from the pressure zone. A grid of walls along the pressure zone in the pressure box define axially shorter length individually pressurizable zones connectable to a pressure source. In an alternate embodiment, three support rollers define two roll beds. The first and third of the rollers are support rollers as described above.
