DEFINITION

Classification: 271/307

Means to strip sheets from engagement with moving conveyor:

(under subclass 306) Apparatus in which the removing means comprises a moving conveyor and in which the transfer means includes means to separate sheets from engagement with the conveyor.

(1) Note. The strippers herein are to be distinguished from mere release means provided as an adjunct to the conveyor to terminate the conveying effect, e.g., cams for opening grippers of a gripper conveyor, means for terminating operation of a suction box for a suction conveyor, etc., and from the guide means commonly provided to guide an already released sheet from the conveyor to the receiving means.
