TITLE Sensor ABSTRACT A sensor for detecting a break in a continu- ously advancing web. A vacuum tube extends through a plenum in a jet body. Air under pressure is introduced into the plenum and discharges through an annular ori- fice surrounding the tube onto a flared end. A low pressure switch in communication with the tube senses the absence of a web from its normal path of advance adjacent the flared end. AD-5162
