Abstract
A full rotary loop taker assembly comprising a loop taker (11) rotatably held in a loop taker support (1), and a driver (3) for rotatively driving the loop taker as it is rotated around a rotative axis (4) intersecting the rotative axis (12) of the loop taker. The loop taker is formed on its bottom surface wall (16) with at least three angularly spaced engaging holes (17a, 17b, 17c). The driver is formed with at least three angularly spaced projections (10a, 10b, 10c) adapted to be received in the engaging holes. During the rotation of the driver, the projections are successively received in the corresponding engaging holes in such a manner as to ensure that there is always at least one projection which has been received in the corresponding engaging hole. Further, to allow passage of an upper thread loop (23), in a predetermined angular range in the rotation of the driver the respective projections are ready to escape from the corresponding holes.
