Abstract: The invention relates to a device (1) for producing a case having a large length for food, in particular for sausages, from a plurality of individual case sections made of casings that contain collagens, such as natural casings or collagen-containing artificial casings, comprising a mandrel (2) and at least two sleeve sections (3), wherein the sleeve sections (3), in order to create an overlapping area (4), are pushed over the mandrel (2) and arranged such as to overlap each other, a heating element (5) for temporarily exchanging heat between the heating element (5) and the overlapping area (4), such that the case sections are at least partially welded to each other in the overlapping area (4), a deformable extension body (6), wherein the deformable extension body annularly surrounds the mandrel (2) and is arranged inside the case sections (3), wherein the deformable extension body (6) is made of an elastically deformable material, and a mold (7) that encloses the mandrel (2) in some sections.
