効果を有する。(Effects of the Invention) That is, the present invention comprises a fabric stretching mechanism that stretches fabric into a cylindrical shape or a shape forming a part of the cylinder, a vertical feed VSa that moves this stretching mechanism in the axial direction of the cylinder, and an interlocking rod that moves together with the movement of the longitudinal feed mechanism and is movable in the longitudinal direction perpendicular to the axial direction; a transmission member fixed to the interlocking rod; and a transmission member fixed to the expansion mechanism and centered on the axial center. a rotatable rotating body, the rotating body is provided with a cam groove into which the transmission member engages, and the cam groove has a shape that makes the rotating body move in direct proportion to the amount of movement of the interlocking rod. , it is possible to accurately transfer the embroidery area of the fabric stretched into a cylindrical shape or a shape forming a part of the cylinder in the circumferential direction, and to simplify this transfer ex1i, and also to provide a signal for controlling the transfer of the interlocking rod. It has the effect of IJ purifying the data input to the transmitting command device.
