There are also provided a color change mechanism (20) for selectively positioning a desired needle at a predetermined operating position in the multi-needle machine head, a rotary hook bed (5) provided for each of the head group for shared use between the machine heads. There is provided a horizontal movement mechanism (30) for disposing the individual machine heads and the color change mechanism for horizontal movement relative to the rotary hook beds and horizontally moving the individual machine heads and the color change mechanism together to place any one of the machine heads in each of the head groups in positional correspondence to the rotary hook bed.
