Abstract
A tensioning machine for use in the heat treatment of textile fabric for controlling the widthwise dimension of the fabric comprises a pair of continuously movable tenter chains for moving the fabric along a path and supported by guides which are coupled to one or more rotatable spindles operable to adjust the guides transversely of such path. One end of each spindle is both rotatable and axially movable and cooperates with a force sensitive device that is operable in response to an alteration in the force applied thereon to generate a signal. Each spindle is coupled to a rotary drive, the operation of which is controlled by the signal generated by the associated force sensitive device.
