ABSTRACT:
An apparatus and process is disclosed in which a web of fabric is conveyed to a centered winder having control of the tensile stress of the fabric to relatively low stress values, and shortly before arranging at the winder, the web of fabric is placed under increased tensile stress by braking. More particularly, the formation of folds is first opposed at low tensile stress before arrival of the web of fabric at the winder. During the winding process itself, the fabric, which is still under slight stress, is applied onto a winding drum and smoothed and is, at the same time, placed under high tensile stress by braking. The individual values of the tensile stress are governed by the material of which the fabric is made and by the construction of the fabric.
