Next, the operation of the support device for a futon or the like according to the present invention configured as described above will be explained.

Futon W between sewing machine head 6 and sewing machine bed 7
To feed the futon W, the front end of the futon W is passed between the tension rolls 35 and 35.
The clip 32 in the open state close to 5 is pulled out with a little space between the fixed piece 32a and the pinching piece 32b, and the rotary drive device 40 is activated.
Due to the operation of the rotary drive device 40, the rotary wheel 17 moves to the third position.
It rotates clockwise in the figure to circulate the transport body 33. A futon W is placed between the fixed piece 32a and the sandwiching piece 32b.
The open clip 32 inserted into the front end of the
It is moved by the movement of the transfer body 33 and comes off the release guide 41, grabs the futon W and moves from left to right in FIG. The subsequent clip 32 that comes in will move through the release guide 41 as described above.
After the gripping piece 32b is closed and the futon W is moved, the futon W is moved between the sewing machine head 6 and the sewing machine bed 7.

After the futon W has been transferred to a predetermined position, the rotation drive device 40 is stopped to stop the movement of the futon W, and then the movable member drive device 30 is activated to rotate the feed screws 22 and 23. The movable members 18, 19 are moved to the left and right along the guide shafts 26, 27 together with the guide rails 12, 13 and the transport body 33, and the futon W is pulled laterally to make it appropriately tensioned. In this state, as usual, the sewing machine main body 5 is operated, the machine frame 1 is moved back and forth, and the sewing machine main body 5 is moved left and right to make the futon W.
