In addition, the feed rolls 37.37 are placed in the first
The tension roll 35 is the one that sends it to the right in the figure.
This is something that adds resistance to the movement of a futon or the like by sandwiching it between them.

The root end 32d of the pinching piece 32b of the clip 32 is pressed against the rotating wheel 16 on the artificial side and the rotating wheel 17 on the exit side, into which the futon etc. W is fed, so that the pinching piece 32b resists the elasticity of the spring. Opening guide (opening/closing mechanism) 41.
42 is fixed to the movable members 18 and 19 by brackets 43 and 14, respectively. Therefore, when the clip 32 moves upward around the rotary ring 16 from the downward return point M (FIG. 3), the root end 32d of the clip 32b is pressed by the opening guide 4I, and the clip 32 is brought into the open state. When the root end 32d of the pinching piece 32b comes off the release guide 41, it is immediately moved to the third position with the futon, etc. W in between.
When it is moved to the right in the figure and approaches the rotating wheel 17, it is released by the release guide 42 and the futon etc. W is released from the clamping.
The feed moves from 0 to the open state around the rotary wheel 17, and then moves to the return surface M.

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.

To feed the futon W between the sewing machine head 6 and the sewing machine head 7, roll the curved end of the futon W onto the tension roll 35.35.
The clip 32 in the open state close to the tension roll 35 is pulled out with a little space between the fixing piece 32a and the pinching piece 32b, and the rotary drive device 40 is activated. The rotary wheel 1 is rotated by the operation of the rotary drive device 10.
7 rotates clockwise in FIG. 3, causing the transport body 33 to circulate. The clip 32 in the open state with the prong end of the futon W inserted between the fixed piece 32a and the pinching piece 32b is connected to the transfer body 3.
3, it is moved and comes off the release guide 4N, grabs the futon W and moves from left to right in Figure 1,
The subsequent clip 32, which travels around the rotating wheel 16 to the feeding surface O together with the transfer body 33, is once opened by the action of the opening guide 41, as described above, and then the clip 32 is opened by the clamping piece 32b.
The user closes the cover, grabs the futon W and moves the futon W, and transfers the futon W between the sewing machine head 6 and the sewing machine bed 7.

After the futon W has been transferred to a predetermined position, the rotary drive device 40 is stopped to stop the movement of the futon W, and then the movable member drive device 30 is activated to move the feed screw 22.2.

．． 27 to the left and right, and pull the futon W sideways to create appropriate tension. In this state, as usual, operate the sewing machine body 5 and move the machine frame l back and forth.
Also, the sewing machine body 5 is moved left and right to bind the futon W.

After binding one futon W, the movable member drive device 30 is operated again to return the movable members 18, 19, etc. to their original states, and the rotary drive device 40 is operated to bind the futon W.
is transferred to the right in FIG. 1, and a new futon W connected to the futon W that has been bound is sent between the sewing machine head 6 and the sewing machine bed 7. At this time, the futon W is moved between the feed rolls 37 and 37, and thereafter is moved by the traction action of the transfer body 33 and the feed rolls 37 and 37. The clip 32 is opened at the rear end of the feeder O by the action of the release guide 42, removes the futon W, and descends to the returner M.

The above is an example of intermittently binding one sheet of a long futon W, but by moving the sewing machine body 5 left and right while moving the futon W4 without stopping the rotation drive device 40, It is also possible to bind futons W continuously. It goes without saying that you can bind a regular futon in one sheet.

As shown in FIG.
This method is suitable for use when employing a sewing method in which 0, l+1151, and lining material 52 are individually sent out from the outer material roll 53, cotton roll 54, and lining material roll 55, overlapped, and then stapled at position A. , as mentioned above, is not limited to this. In FIG. 4, reference numerals 56, 57 and 58 are cushion rolls, and 59 is a cutter.
