ABSTRACT OF THE DISCLOSURE Apparatus for the external support of tubular films of thermoplastic material consists of groups of outwardly curved supporting segments disposed successively in the direction of withdrawal of the tubular film. These supporting segments are adjustable simultaneously and in the same sense to different tubular film diameters, and for their adjusting movement they are each connected with a turning bar which is common to all supporting segment groups and journalled in a supporting frame and with a holding bar aligned parallel thereto which again is common to all supporting segment groups.
