(under subclass 520) Subject matter wherein the apparatus includes a device to monitor a condition of the coiling operation for issuing a regulating, alarm, indication, or halt signal.
(1) Note. A quantitative control as well as an alarm or stop is found here unless provided for earlier (e.g., as a tensioning or cutting control); however, a tension-triggered mechanism to simply halt winding (e.g., during a material jam or supply exhaust) is placed here.
SEE OR SEARCH THIS CLASS, SUBCLASS:
333+, for a device for detecting a need and causing a halt of winding or a reversal of the winding direction of a magnetic tape or photos:graphic film winding or unwinding device.
334+, for a device for detecting and controlling the speed of a magnetic tape or photos:graphic film.
410+, for a detector combined with a control for tensioning.
523+, for a detector in a control for a cutter in a convolute winding machine.
SEE OR SEARCH CLASS 250, Radiant Energy, for a detail of a photoelectric device, per se, or in combination with generalized structure, particularly
200+, and 559.01+.
271, Sheet Feeding or Delivering,
226+, and 256+ for alignment and stopping sheet feeding that may be analogous to a corresponding operation in winding.
318, Electricity: Motive Power Systems, for a control device for an electrical device including a motor or brake of general use, particularly
6, 7, and 362+.
356, Optics: Measuring and Testing, particularly
