Abstract (en)
[origin: EP3686332A1] A start restriction method of a pile loom (1) from which an operator removes a defective yarn when a weft-insertion failure occurs includes previously storing a start reverse-rotation number set so that a same numerical value as a pile step is assigned to a loose pick and a first fast pick included in pile picks, and 1 is assigned to second and later fast picks; when a weft-insertion failure occurs, reading from the start reverse-rotation number and storing as a current value, a numerical value corresponding to the pile pick with the failure; updating the current value by adding 1 (subtracting 1) every time when a rotational angle of a main shaft (24) passes 0° by forward (reverse) rotation of the main shaft through a subsequent motion of the loom; and inhibiting start of the loom by an operation on an operation button (26) until the current value becomes 0.
