ABSTRACT:
An improved measuring device for measuring the unit weight of sliver as it passes through a trumpet includes a trumpet gauge plate for supporting the trumpet and a vibration compensating element mounted on the plate. A plurality of strain gauges for detecting deflections are mounted on front and rear surfaces of a central portion of the plate adjacent a lower portion and the compensating element. The plate is mounted on support means, illustrated as a pair of spring supports, which allow the trumpet to move in response to an overload to eliminate damage to the plate, particularly its central portion where the strain gauges are mounted and to return to its normal position after the overload is gone. During normal operation, without an overload, deflection sensing produced by external vibrations cancel out to produce an accurate measurement of the sliver weight and during an overload, the trumpet moves to a new position to avoid damage to the plate and then returns, after the overload is gone enabling the measuring operation to continue.
