In order to achieve the object of the present invention described above, the invention of claim 1 is a sewing head fixed on the bed (BED) having a needle bar mechanism, balance mechanism, the upper fabric transfer mechanism, and the fabric It consists of a unit that achieves sewing by synchronously operating with each mechanism in the sewing head provided with a transfer mechanism, and a wheel body and a fabric transfer tooth that face the needles face the needle. In the sewing machine fabric transfer device composed of a bag that is located on the left side and the right side of the needle supporting the part,

A negative part is fixed to the upper end of a sub-shaft, a sub-shaft is fixed to the pipe | tube in a subshaft, and is simultaneously supported by a side by a shaft Rotate freely,

The tubular gear is fixed to the pipe in the auxiliary shaft, and at the same time the bolt is engaged with the intermediate gear of the needle bed with a bolt. ) Is fixed to the bag with screws, and the intermediate gear is freely rotated on the upper part of the needle seat under the action of the guide plate, and the teeth of the needle seat outer periphery The shape part coincides with the fabric feed tooth, and is additionally engaged with the fabric feed tooth, and the other end of the intermediate tooth is engaged with the ornamental tooth tooth,

The electric mechanism composed of the tubular gear, the fabric feed tooth, the intermediate gear, etc. is made in a longitudinal arrangement in appearance and the distance from the needle to the vertical surface of the needle plate is reduced.
