ABSTRACT:
A method of stopping a loom, whose operation is controlled by a microcomputer, at a predetermined position thereof is disclosed herein. In view of the phenomenon that the load on loom operation is varied with the operating cycles thereof depending on the texture of fabric to be woven, but the variation takes place in repeated cycles of similar patterns each including different phases in succession of a known number, the method according to the invention comprises the steps of detecting the deviation of the actual stop position from the predetermined position resulting from the preceding loom braking operation, executing arithmetic operation on data regarding said deviation for compensation thereby to adjust the position at which brake is to be applied in the current braking operation, and applying brake when said position determined through said arithmetic operation is reached by the loom, wherein such steps are carried out in each group of the phases that correspond to each other in similarity.
