PURPOSE: To make it possible to tuft a circular design on base cloth by making a rotation shaft of a looper bar installing many loopers and a rotation shaft of a needle bar installing many needles to synchronously rotate and vertically reciprocate on a same shaft line.
CONSTITUTION: A looper rotating shaft 16 bearing a looper bar 13 installing many loopers 11 and a needle rotating shaft 17 bearing a needle bar 14 installing many needles 12 are synchronously rotated around a line parallel to a needle shaft core as a center of the rotation and simultaneously made to vertically reciprocate. By said driving of the both rotation axes 16 and 17, the loopers 11 and the needles 12 are vertically reciprocated and simultaneously made to synchronously rotate.
