ABSTRACT:
A gauge for measuring or monitoring the tension in a running thread comprises three rolls arranged such that a thread running under tension in driving engagement with the three rolls exerts a radial force on the middle reaction roll which includes a pneumatic radial bearing. The pressure at selected points in the annular layer of pressurized gas of the pneumatic bearing is sensed to indicate the tension in the running thread.
