Abstract: A device for opening an end region of a bag body, which end region extends between an open tube body end and a bottom central line, having a transporting device, on which the bag body is transportable with adjacent tube walls at a transport rate (V) in a transporting direction, and suction devices arranged on both sides of the bottom central line, which are driven so as to be moveable transversely back and forth to the transporting direction, wherein the suction devices are movable in addition in the transporting direction back and forth. The suction devices are mounted at first articulated joints, wherein at each first articulated joint there are hinged two pivoting arms pivoting relative to one other, wherein each pivoting arm is pivotingly connected to a positioning pivoting arm by means of a second articulated joint and wherein each positioning pivoting arm is movably driven.

Abstract: The present invention relates to an x-ray image recording system for recording x-ray projection images of alignment information for recorded x-ray projection images, comprising an x-ray tube and an x-ray image detector being arranged in the optical path of the x-ray tube for recording x-ray projection images of an object that can be disposed and/or that is disposed between the x-ray tube and the x-ray detector in an imaging region in a locally fixed manner, wherein the x-ray tube and the x-ray detector are disposed in a locally fixed manner relative to each other, and can be moved about the imaging region, at least in sections, a position sensor being disposed relative to the x-ray tube and the x-ray detector in a locally fixed manner, by means of said sensor the current alignment of the x-ray tube and the x-ray detector can be determined relative to a predefined reference direction at the moment of recording an x-ray projection image, and a storage unit for storing recorded x-ray projection images together w
