A device for finishing woven denim textiles is described which, proceeding from unfinished goods, is supposed to be brought to predetermined reference values for finished width, skew and woof thread density. The device is supposed to be designed for continuous operation for regulating all three reference values. According to the invention, a stretching device, such as a rack or a loop dryer, and a shrinkage system for continuous throughput of the woven denim textile, are arranged one after the other. Directly behind the stretching device, particularly, at the same time, behind the shrinkage system, a single measuring device, preferably as an optical detector having a digital camera, is provided. The measuring device is designed, at the same time, for detecting the actual values of finished width, skew and woof thread density, and is supposed to be connected, in control circuits, with devices for achieving the reference values.
