ABSTRACT:
An apparatus for cutting limp sheet material with a rigid, cantilevered blade that is reciprocated as it advances along a cutting path through sheet material employs a load sensor to measure lateral loads applied to the blade by the sheet material during cutting. A load signal from the sensor is applied to the blade controls through a variable gain feedback circuit and causes the blade to be oriented slightly toward the side of the cutting path from which an unbalanced load is applied. The adjustment of the gain in the feedback network is made by means of speed sensors which measure the rate at which the cutting blade advances through the sheet material and adjust the feedback gain in inverse relationship.
