Abstract
A process for producing multi-layered tubular bodies, wherein each tubular body has at least one dividing wall extending along its length to form adjacent longitudinal chambers. The process comprises fastening a dividing strip to a foil ribbon in a parallel arrangement to the foil ribbon, and joining the longitudinal edges of the foil ribbon together to form an endless tube. This tube can then be cut to produce multi-layered tubular bodies.
