Abstract
In terms of their operational reliability, apparatuses for discharging from a magazine of flat-laid packaging container blanks of the type used for manufacturing packaging containers for liquid contents are greatly dependent upon the quality of the packaging container blanks themselves. In the event of variations in friction or abutment pressure between the packaging container blanks, there is a risk that more than one blank is discharged at a time, or alternatively that no blank is discharged at all. In order to ensure a dependable function with repeated discharge of one blank at a time and at a predetermined rate, the apparatus according to the present invention includes a pivotal lever provided with at least one suction cup. The lever displaces one packaging container blank at a time from the discharge end of a magazine past a segmented wheel which grasps the discharged blank between a rubber cladding and a counter wheel for further advancement to a conveyor.
