Abstract
A method and apparatus for shrink finishing a traveling textile fabric web includes a fabric drawing-in unit, a wetting unit, a fabric stetching unit, a fabric shrinking unit, and a fabric drying unit. Individual drives for each unit are provided, with the drive for the shrinking unit being the main drive and being operated as a function of the lengthwise elongation of the fabric web by the stretching unit to achieve a desired overall degree of lengthwise shrinkage of the fabric web. Automatic control of the system is provided by digital synchronization of the several drives and through moisture sensors which monitor the moisture content in the fabric web in advance of the shrinking unit and after the drying unit and by tension sensors which monitor the actual tension in the web intermediate each successive pair of the units.
