ABSTRACT:
An apparatus for continuously transporting, separating, and changing the path of webs in machines for processing webs prior to further processing are disclosed. A web consisting of at least one ribbon of material is conveyed by a pair of nip rollers arranged in a first transport path. When it is desired to separate and convey the web, for example when the web is of insufficient quality, a separating flap pivotally mounted on a first rotary axis located above the first transport path pivots downward cutting and directing the web to a second transport path. A blade flap pivotally mounted on a second rotary axis located below the first transport path opens and closes the transport path to the web. When the blade flap is in the closed position it bridges a gap between a lower guide and a guide section to allow the conveyance of a web through the first transport path.
