Abstract
The invention relates to a method of applying pouring elements to flat-gabled packages filled with free-flowing products, where the pouring elements are glued to the individually conveyed and sealed packages, where a fully automatic application operation is possible, where trouble due to improper positioning and incomplete gluing of the pouring elements is reliably prevented. In addition, it is desirable to prevent packages not having the pouring elements attached to them from leaving the gluing station. This is accomplished by the following steps: horizontal conveyance of successively arranged packages standing upright, separation of the packages and introduction of the separated packages into a gluing station depending on the presence of a pouring element, applying adhesive to the pouring element and gluing and pressing the pouring element to a predetermined area of each package.
