Abstract
An apparatus and method for correcting the bow distortions in a fabric web during a tentering operation is disclosed, and which includes a tension applying means at each of the entry and exit ends of the tenter frame, and such that a tension is applied at each of the respective opposite ends of the tenter, with the applied tensions being directed in opposite directions. A sensor is provided for detecting either a leading or a trailing bow in the advancing web, and a control system is provided which acts in response to a signal from the sensor to change the tension applied at one or both ends of the tenter frame and thereby straighten the bow.
