Abstract:
1. A device for packaging products in a foil package, comprising feed-through means for continuously supplying a foil web from a supply roll to a corner forming unit, said corner forming unit comprising, in succession, a curved deforming edge for deforming the flat foil web to a curved foil web having a reduced width, deforming means for forming a profile in the curved foil web, a roller-for flattening the profiled foil web, with the reduced width of the foil web at least substantially being maintained and overlapping sections of said foil web being formed at the location of the profile, and first sealing means for sealing said overlapping sections of said foil web, said device further comprising a shoulder element, to which the foil web comprising the sealed overlapping sections is supplied by the feed-through means for deforming the foil web into a tube at the location of the shoulder element, along the path of which tube second sealing means are disposed for joining longitudinal edges of the foil web together and forming a sealed bottom side and upper side of a package perpendicular to the longitudinal direction of the tube, with the sealed overlapping sections forming the corners of the package, wherein the deforming edge and the deforming means form part of an exchangeable switch unit and in that the first sealing means is movable along at least one guide extending parallel to the central axis of the roller, with the corner forming unit comprising aligning elements associated with the first sealing means, which aligning elements cooperate with further aligning elements associated with the deforming means for correctly positioning the first sealing means relative to the deforming means.
