Abstract

There is disclosed apparatus, for counting a stack of sheets, of the kind (hereinafter referred to as "the kind described") comprising a counting head which in use is traversed along a corner of the stack, the head having a suction blade provided with a suction orifice for insertion in the corner of the stack, which blade is oscillatable about a horizontal axis to separate a corner of a sheet in the stack adhered by suction to one side of the blade from the next stack, and a wiping pin movable in an elongate orbit around the blade to transfer the corner of the sheet from the said one side of the blade to the opposite side thereof, and means to count the number of transfer operations effected, wherein there are provided means to traverse the counting head downwardly past a corner of a stack to be counted and means to move said wiping pin in a generally downwardly inclined elliptical orbit around the suction blade, comprising first means to mount the wiping pin for eccentric rotation about a first axis, second means to mount said first mounting means for eccentric rotation about a second axis, and means to drive said first and second mounting means about said first and second axes re…
