Abstract: Shown and described is an apparatus for the pre-folding of packaging sleeves including: at least one folding device with folding tools for pre-folding the bottom surfaces of a packaging sleeve and at least one folding device with folding tools for pre-folding the gable surfaces of a packaging sleeve. In order to achieve a precise and rapid pre-folding of the gable surfaces of a packaging sleeve on a compact system, it is proposed that all the folding devices are mounted movably in the vertical and in the horizontal direction. In addition, a method for the pre-folding of packaging sleeves is shown and described.
