ABSTRACT:
A measuring roller, which may be a driven chill roller provided with a coolant supply and return assembly, is utilized as a web tension measuring roller. A measuring cage includes a flanged ring fixed to a side frame of the printing machine and a retainer ring joined to a bearing for the measuring roller. These two rings are connected by a plurality of flectional beams that are provided with strain gauges. Changes in web tension are sensed by the strain gauges in response to deflection of the flectional beams.
