Abstract

An apparatus for the withdrawal of flat carton blanks made of paperboard, boxboard or corrugated board from a stack located in back of a retaining mechanism, which comprises conveyor belts and belt guides disposed beneath the stack of blanks for the controlled withdrawal of the lowermost blank and, directly adjacent to such takeoff conveyor and driven in synchronism therewith, a conveyor for the onward transportation of the individually withdrawn blanks. The belts of the takeoff conveyor under the stack are carried downwardly at an acute angle relative to the belt guides starting in the vicinity of retaining mechanism and there is disposed below said conveyor belts, in the vicinity of said retaining mechanism an eccentrically mounted roll whose eccentric shaft is driven by a drive controlled in synchronism with the drive of the takeoff conveyor.
