A system for the production of a medical product, above all in the form of an ostomy bag, as well as a method for operation of such a system, uses a highly flexible modular system concept, in which individual feed lines for semi-finished products are provided. The feed lines can transfer semi-finished products to a main line in pre-assembled manner. In the main line, ultimate processing of the semi-finished products to produce the finished product or a further semi-finished product takes place, with the greatest possible work precision, in contrast to conventional systems that guide different film systems in different planes at a distance from one another, to allow pre-processing steps, before bringing the films together in one plane and welded to one another.
