1. A curved workpiece fabric holder device for use in an embroidery machine having at least one cylinder bed extending in a frontward/rearward direction, and a fabric feed frame movable in the frontward-rearward direction and a lateral direction perpendicular thereto, the holder device comprising:

  • a base frame positioned adjacent the at least one cylinder bed and movable in the frontward/rearward direction;

    a rotary frame rotatably supported by the base frame and positioned to surround the at least one cylinder bed, the rotary frame providing a rotational point of origin;

    a workpiece retainer for retaining a curved workpiece and detachably mounted on the rotary frame;

    a translation mechanism connected between the fabric feed frame and the rotary frame for translating the movement of the fabric feed frame in the lateral direction into a rotational movement of the rotary frame; and

    an adjusting mechanism provided to the translation mechanism and selectively releasing the rotary frame from the fabric feed frame for adjusting an initial rotational position of the rotary frame relative to the base frame to adjust the rotational point of origin regardless of the movement of the fabric feed frame.
