In this production process, it is usually completed by manual operation or separate operations of multiple single machines with different functions.

[0003] After the rubber band completes the cutting and material pulling processes, a special clamping and turning device is required to turn and roll the rubber band into a circle. For example, a rubber band forming device for a rubber band machine disclosed in Chinese Patent CN202021050412.3 includes a frame, on which two rotary drive sources are arranged side by side, and the output end of the rotary drive source is connected with a clamp for clamping the end of the rubber band.
