Elastic waistband diaper machine is a device specially designed for the production of diapers with elastic waistbands. By controlling the tightness of the diaper waist, the machine ensures that the diaper can be adapted to the waist circumference of different babies, providing a comfortable fit. Depending on the search results, such machines may include devices for controlling the tightness of the elastic waist, such as the upper transfer roller and the lower transfer roller and the tightness mechanism arranged between them. The elastic mechanism may include left and right elastic wheels, which are controlled by a power shaft and transmission mechanism to ensure the stability and correct position of the diaper during delivery.
