ABSTRACT:
Disclosed is a gauge for measuring the weighting force on a textile cot roll. The gauge consists of a pair of pivoted levers having portions extending forwardly of the pivot point which include reduced-thickness ends thereon adapted to be inserted into an opening between a cot roll arbor and a drive roll therefor. The drive roll-contacting lever portion is forked. The arbor roll-contacting lever arm is mounted between the forked arms of the arbor roll-contacting lever and is offset from the pivot point. This allows the lever ends to separate when the rear portions of the lever arms are forced apart by a screw threaded element extending through the rear portion of one of the levers into contact with the opposing portion of the other lever. A strain gauge is mounted on the forwardly extending arm of the cot roll arbor-contacting lever to sense flexure thereof as a change in electrical resistance and is operably connected to an electronic readout instrument which translates changes in the electrical resistance into a weighting force on the textile cot roll when the cot roll is forced away from the drive roll by separation of the forward arm portions of the pivoted levers.
