Baby diaper transversal rubber band type elastic waistline exerting and traversing device

The utility model relates to a baby diaper transversal rubber band type elastic waistline exerting and traversing device, which is characterized in that a synthetized rubber band elastic waistline is firstly cut off and is transmitted to a negative pressure traversing device, and comprises a rubber band uncoiling mechanism, a rubber band gluing device, a non-woven fabric covering device, a drawing wheel device and a negative pressure traversing wheel device, and a cutter assembly is positioned between the drawing wheel and the negative pressure traversing wheel device. The device has the advantages that the device is subjected to cutting and then turning, so the technology is advanced, and the defects in the background art is avoided; and the speed is high and the performance is reliable, under the speed of 130 slices/minute, due to the accurate coordination of a cutter and a bottom cutter block, the rate of finished products can reach over 99%.
