Abstract
An automatic printing machine which forms an image on a sheet substrate has a multi-mode sheet output station in the form of a brush decision gate having a bidirectionally rotatable cylindrical fibrous brush to direct sheets upwardly over the top of the brush in a first sheet transport path when rotated in a counter clockwise direction and downwardly under the bottom of the brush in a second sheet transport path when rotated in a clockwise direction, the brush being selectively rotated in a clockwise and counter clockwise direction.
Claims13
An automatic printing machine comprising means to form an image on a sheet substrate at a given process speed and a multi-mode sheet output station comprising a brush decision gate having a bidirectionally rotatable cylindrical fibrous brush to direct sheets upwardly over the top of said brush in a first sheet transport path when rotated in a counter clockwise direction and downwardly under the bottom of said brush in a second sheet transport path when rotated in a clockwise direction and means to selectively rotate said brush in a clockwise and counter clockwise direction at a speed faster than the process speed of said printing machine and wherein each of said first and second paths has at least one pair of bidirectionally rotatable nip rolls to selectively drive a sheet forward and backward through said nip.
