  • a yarn detected by a dropper such as an H1 feeler sensor or a warp breakage sensor is made an object of the foregoing yarn troubles.
  • Other yarn troubles namely, those detected by an H2 feeler sensor, a package sensor, a selvedge yarn breakage sensor and a catch code breakage sensor may be likewise treated as objects of the yarn troubles.
  • inquiries from the managing supporter 16 corresponding to the detected yarn troubles may be prepared in the image plane of the touch panel 24.
  • each loom may have one managing supporter.
  • the managing supporter 16 may have its function incorporated into the information terminal of the loom.
  • a storage means for storing each yarn trouble together with the time of its occurrence is provided within the information terminal 14, but it is possible to transmit information every time the information terminal 14 calls in response to the call.
  • the location of the storage means is not restricted to that shown in the drawings.
  • the method can be widely applied to a warp preparatory machine such as a warper for taking up a lot of warp yarns round a beam and a warp sizer, as well as to other textile machinery.
