A sensor system for determining the position of an edge of a moving web of material travelling along a predetermined travel path. the sensor system comprising a transmitter/receiver assembly, a beam reflector assembly and sensor signal processing. The transmitter/receiver assembly is positioned adjacent to the travel path of the moving web of material. The transmitter/receiver assembly has a transmitter transmitting a light curtain across at least a portion of the travel path, and a receiver receiving a shifted light curtain transmitted across at least a portion of the travel path and generating video output signals indicative of the position of the edge of the moving web of material. The beam reflector assembly is also positioned adjacent to the travel path of the moving web of material such that the travel path passes between the transmitter/receiver assembly and the beam reflector assembly. The beam reflector assembly receives an unblocked portion of the light curtain, shifts the unblocked portion of the light curtain a distance laterally to form the shifted light curtain, and transmits the shifted light curtain across the travel path of the moving web of material.

A sensor system for determining the position of at least one edge of a web of material is provided. The sensor system includes a transmitter and a receiver disposed on opposite sides of the web. The transmitter is capable of selectively transmitting ultrasonic signals, and the receiver is capable of receiving such ultrasonic signals and generating output signals indicative of the position of the web. The sensor system further includes a sensor drive circuit adapted to periodically transmit to the transmitter a transmitter drive signal representative of substantially one cycle of a signal, and to receive signals from the receiver with each signal being indicative of the position of the web.

A sensor system for determining the position of at least one edge of a web of material traveling along a predetermined path. The sensor system has a transmitter assembly capable of selectively transmitting at least one collimated light curtain and a receiver assembly capable of generating output signals in response to receiving portions of the collimated light curtain transmitted by the transmitter assembly. The receiver assembly is spaced a distance from the transmitter assembly so as to define a travel path therebetween whereby at least a portion of the web of material traveling along a predetermined travel path blocks at least a portion of the collimated light curtain transmitted by the transmitter assembly. The output signal generated by the receiver assembly is indicative of the position of the web of material as the same is moved along the travel path between the transmitter assembly and the receiver assembly.
