Elastic ribbon machine

The invention discloses an elastic ribbon machine. By control over the rotation angle of a first motor, the lengths of conveyed elastic ribbons can be set, elastic ribbons conveyed in through a first feeding driving wheel are stored between the first feeding driving wheel and a second feeding driving wheel, and therefore the second feeding driving wheel is matched with a roll material coiling device to continuously output the elastic ribbons. In a feeding process, the elastic ribbon machine can conduct joint examination and ironing on the elastic ribbons, and the elastic ribbons at the discharging port of the second feeding driving wheel can be cut off automatically through a cutting device. The roll material coiling device clamps materials through a third fixture and rotates to enable the two ends of each elastic ribbon to be respectively sent to a first fixture and a second fixture; the first fixture and the second fixture clamp the two ends of each elastic ribbon and enable each elastic ribbon to form an elastic ring through rotation motion, and the two spliced ends of each elastic ring are fixed on a material supporting frame to facilitate following sewing fixation. The roll material coiling device has the advantages of being simple in structure and achieving automatic control, and greatly improves the coiling speed of the elastic ribbons.
