  • Patent number: 11584551
    Abstract: An apparatus for producing packaging, in particular composite packaging for liquid foodstuffs, having a cross-sectional area that decreases in the pour-out direction in the gable region. The packaging is composed of a sleeve having a gable region having a plurality of gable faces and a pouring element. The apparatus has at least one rotatable mandrel wheel having a plurality of mandrels for holding the sleeves. Additionally, a method for producing such packaging and a gable press for use with the aforementioned apparatus. In order to allow easier and more cost-effective production, it is proposed that the apparatus has a gable press, assigned to a single mandrel wheel position, for folding the gable region, for connecting all the gable faces of the gable region of the sleeve to the pouring element and for sealing the protruding ears in the same mandrel wheel position.
