Abstract (en)
[origin: EP0140081A2] A method of and apparatus for intermittently advancing a continuous flexible web of material at a substantially constant tension is disclosed. The web of material is unwound from a supply roll, folded longitudinally and drawn past a package forming apparatus by two roll pair assemblies spaced along the path of travel of the web. The diameters of the rolls of the downstream roll pair are greater than the diameters of the rolls of the upstream roll pair so as to impart a constant tension to the web traveling between the two roll pairs to thereby improve the uniformity and yield of the packages formed in the apparatus.
