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.

A device for processing, in particular for ultrasound welding, of packaging sleeves and/or packagings includes at least two tools for processing, in particular for ultrasound welding, of packaging sleeves. Each tool has an operating region. The tools are supported in such a manner that there is produced between the operating regions a gap whose longitudinal direction corresponds to the transport direction of the packaging sleeves, and the tools are supported in such a manner that the size of the gap can be changed. In order also to enable continuous welding of the packaging sleeves in a reliable manner with changing material thicknesses, there is provided at least one parallel spring on which at least one of the tools is movably supported transversely relative to the transport direction of the packaging sleeves.

A mandrel wheel for producing packages is illustrated and described, including: a mandrel wheel shaft having a central axis, a plurality of mandrels attached to the mandrel wheel shaft, an inflow for a coolant and an outflow for the coolant. The mandrels form at least one mandrel group, the mandrels of which are arranged in a plane perpendicular to the central axis of the mandrel wheel shaft. Each mandrel has a hollow space for the coolant, which is connected to an inlet and to an outlet separate from it. At least one distribution element is provided, which connects all inlets of a mandrel group to the inflow and which connects all outlets of the same mandrel group to the outflow, so that the mandrels can be cooled more effectively.
