Abstract: A method of measuring and expressing the unwound amount or residual amount of a web roll, such as carbon film roll or printing paper roll in terms of a unit length of the web roll includes the steps of: starting a count of pulses to be produced by a rotation displacement detecting sensor for each predetermined angle of rotational displacement when the residual amount of the web roll is considered to have been reduced to a predetermined value; and emitting a warning signal when the count reaches a predetermined count number (initially set on the basis of the average value of the amounts of unwinding rotation of the web roll per unit length) during the time when the web roll is unwound and fed by a unit length from the count start time.

Abstract: A detector on a wire lead machine includes a pair of contacts biased into a normally closed position. The wire is fed between the contacts, keeping the contacts open, and the insulation on the wire prevents electrical conductivity between the contacts. If the wire runs out, the contacts close to shut off the machine. Additionally, a splice on the wire establishes an electrical path between the contacts and, again, the machine is shut off. The detector includes a detection circuit which generates a control signal. In the event a splice is passing through the contacts, the detection circuit generates a control signal having a relatively short time duration (as for example, 100 microseconds) and holds the signal for a sufficient time period (as for example, 500 milliseconds). This allows a suitable control means (which may include a microprocessor) to shut off the machine because of either wire runout or a splice on the wire, thereby preventing serious damage to the machine and maintaining productivity.

The cable and drum are configured such that the projecting length of cable rotates about its length as an incident of the drum being rotated about its axis. A brake is provided for stopping rotation of the drum and thereby rotation of the projecting length of cable so as to prevent torquing of the projecting length of cable as when the projecting length of cable is prevented by freely rotating by an obstruction encountered in a conduit passageway.

Abstract: A method and apparatus for reliably detecting the occurrence of a web break in a web processing system is disclosed employing a non-contacting, non-optical sensor to detect the presence of the web. Cushion pressure in a cushion pressure zone adjacent the web is sensed to determine a web break condition. A sensor block is mounted within an enclosure through which the web passes. The sensor block is configured to sense the cushion pressure in the region between an air bar and the web. The cushion pressure is communicated outside the enclosure to a transducer which compares the cushion pressure to either the internal ambient pressure of the enclosure or to atmospheric pressure. The resulting differential pressure is compared to a threshold differential; if the measured differential pressure drops below the predetermined threshold pressure, a web break is indicated and web processing is terminated.
