    • A sensor system for determining the position of at least two edges of at least one web material traveling along a predetermined path. In one embodiment, the sensor system has at least one transmitter block having a plurality of transmitters capable of selectively transmitting ultrasonic signals and at least one receiver block having a plurality of receivers capable of generating receiver output signals in response to the receivers receiving at least a portion of the ultrasonic signals transmitted by the at least one transmitter block. The receiver block is spaced a distance from the transmitter block so as to define a continuous sensor field of view therebetween whereby at least a portion of the at least one web material traveling along a predetermined travel path interferes with at least a portion of the ultrasonic signals transmitted by the at least one transmitter block. The receiver output signals generated by the at least one receiver block is indicative of the position of the web of material as the same is moved along the travel path between the transmitter block and the receiver block. In an alternative embodiment, the functions of the at least one transmitter block and the at least one receiver block are performed essentially equivalently by at least one transceiver block and at least one reflector.

    • 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.
