  • a cloth fell controller disclosed in JP-A 54-106661 is a representative filling bar preventing techniques. This known cloth fell controller prevents the formation of filling bars due to the elongation of warp yarns while the loom is stopping by turning the warp beam on the loom in the normal direction to move the cloth fell so that warp tension decreases.

  • This leveling device prevents the formation of filling bars due to the elongation of warp yarns while the loom is stopping by driving the heddle frames on the loom so as to reduce the size of a warp shed, preferably, so as to close a shed after the loom has stopped.
  • a kick-back device disclosed in JP-A 61-63749 prevents the formation of filling bars by turning the warp beam in the normal or the reverse direction through a predetermined angle to displace the cloth fell prior to restarting the loom.
  • a starting torque setting device for setting a starting torque of a motor for driving the main shaft of a loom is disclosed in JP-A 57-51846 .
