Abstract
A forming shoulder for forming a film tube from a flat film web and a method for producing a forming shoulder. The forming shoulder comprises a shoulder piece and a prism piece which are connected to each other along a forming edge, the shoulder piece having an outer shoulder surface via which the film web can be guided to an entry opening of the prism piece limited by the forming edge, the forming edge being made of at least one metal piece, a plastic shoulder piece and/or a plastic prism piece being molded onto the metal piece.
