ABSTRACT OF THE DISCLOSURE A device for axial shirring of synthetic tubular material by forming a continuous helical fold. As the unshirred tubular material moves along a mandrel, it is engaged by the teeth of at least three shirring tolls having their axes located in a plane transverse to the mandrel. This assembly of shirring rolls revolves about the mandrel axis and the individual shirring rolls have peripheral teeth parallel to their respective axes. The shirring rolls are interconnected for timed rotation with each other and preferably they are all driven from the assembly revolving drive means. The teeth of the rolls have arcuate recesses or grooves which correspond to the mandrel surface, which overlap each other circumferentially about the mandrel surface, and which are so positioned about their respective axes that the teeth of any given shirring roll directly follows a tooth of the pre- ceeding shirring roll taken in the direction of revolution and in the direction of advance of the tubular material.
