Method and packaging machine for producing a multipack

A method for grouping at least three package units into a package stack, the method comprising the steps of:

• feeding the individual package units using a feeder to a grouping station;
• stacking the package units one on top of the other through the grouping station so as to form a package stack;
• depositing the package stack on a conveying system;
• feeding the package stack to a labeler through the conveying system;
• applying a label to the upper surface of the package stack through the labeler, the label having a lateral first projecting end that projects beyond the package stack;
• folding the first projecting end of the label around a first upper and a first lower edge of the package stack;
• pressing the first projecting end onto a lower surface of the package stack;
• pressing at least one tab, which is connected to a main surface of the first projecting end in a hinge-like manner, onto a side face of a central package unit of the package stack.
