Abstract (en)
[origin: ES477428A1] A tube of flexible material moving longitudinally undergoes transition between annular cross section and flattened straight cross section, without change in the length of perimeter of its cross sections, by one stage of changing between the annular cross section and a rectangular cross section, and another stage of changing between that rectangular cross section and the flattened cross section through successively longer and narrower rectangular cross sections. The method is applicable to material produced by a circular knitting machine. Preferably there is a polyhedral guide within the tube.
