Summary:A novel control unit for driving plural loopers provided with a tension constant automatically adjusting circuit in which a looper speed on its slave side is controlled such that a plurality of loopers having different amounts for moving the loopers and different strand numbers pass through the same % positions at the same time in order to control these plural loopers, and the number of times in operation for correcting an error of % position which takes place at the time of stopping transference of the plural loopers is minimized.
