s1, starting an automatic program;

s2, sleeving the rubber band and the clothes on the turntable 51, starting the control mechanism 6, and driving the turntable 51 to horizontally open by the supporting mechanism 4 to tighten the rubber band and the clothes;

s3, when the supporting mechanism 4 reaches the horizontal movement limit, one end of the supporting mechanism 4 is closed to enable the other end to be splayed, the rubber band and the clothes are pushed backwards to be aligned with the front plate 2, and the position of the clothes is adjusted again;

s4, the control mechanism 6 rotates again, the supporting mechanism 4 continues to fold, the limitation is removed, the straightening is recovered, and the control mechanism 6 stops working;

s5, the supporting mechanism 4 drives the rubber band and the clothes to rotate and sew the clothes, and in the process, the auxiliary mechanism extends out to stabilize the rubber band and prevent slipping;

and S6, after sewing, the control mechanism 6 continues to work, the supporting mechanism 4 is folded to the initial position, and the clothes with the sewn rubber band are taken down.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
