ABSTRACT:
A device for positioning a sheet separator for a stack of sheets in a sheet feeder includes a drive for the sheet separator operable for moving the latter in two opposite directions. A stop gauge for the rear edge of the sheet stack is slidably supported on an insulating block which is rotatable on the sheet separator. The lower end of the stop gauge is provided with a feeler roller to engage the upper side of the stack, and the opposite end of the stop gauge is provided with a flag cooperating with an inductive switch. The latter switch controls the direction of rotation of the driving motor for the separator. The rotary block controls another switch which stops the motor when the separator attains its desired position. A light barrier switch is arranged at the level of the desired height of the stack and determines the active or inactive condition of the positioning device.
