Abstract
A warp insertion monitoring method and apparatus for positively protecting woven cloth from defects due to warp insertion error or failure. A warp detector is disposed on a loom so as to have a warp presence/absence detection region located at a front or rear side and in the vicinity of a reed which serves for beating a weft inserted through a shedding formed by the upward/downward motion of healed frames against a cloth fell. The presence or absence of abnormalities in respect to the positions at which warps are inserted through the reed is identified on the basis of detection information available from the output of the warp detector. Detection timing for the warp detection information is so established as to fall within a period during which the loom is stopped, so that the presence or absence of errors in respect to the warp insertion can be detected before the loom is restarted.
