Web controlling apparatus |
摘要 |
An apparatus for controlling an outgoing web leaving an air cushion turning bar, which enables a convenient transport of longitudinally curved webs over such air turning bar. The apparatus comprises at least one axially displaceable roller adapted to be moved laterally upon a deviation in the web to bring the same to its outgoing path, and a second roller capable of bodily tilting movement and preferably axial movement as well, to differentially lengthen the path of the web edge margin remote from the direction of deviation.
