Disclaimer (all) which will not appear on the advertisement page: Revised 9/5/2017 1. Manufacturing method of the absorbent product incorporating the first wadding (10A) which makes up the waist band. The front (10) and the second wadding (20A), which make up the rear lumbar section (20) .The method consists of step A of transporting the first sheet (10A) and the second wadding ( 20A) in the superimposed state between the anvil part (220) and the vibrator (330), which is provided to An ultrasonic attachment (100) and a procedure B of pre-defined area welding (60) were provided with the first wadding (10A) and the second wadding (20A7. With the interval that has been set Before in The transport direction (MD) of the first wadding (10A) and the second wadding (20A) by output vibration rate Sonic from the output part (332) of the vibrator (330) to the previously designated region. Vibration, the sonic rate that has been caused. By the oscillator (310) provided for the ultrasonic welding device (100) where the output part consists of The central output (332A) section is configured for high speed output. Vibrates the sonic rate to the middle (60C) of three equal regions, each of which The pre-assigned region was divided in the machine cross-direction (CD) cutoff direction (MD) and the two end-output sections (332B) that were configured to output vibration-rate. Sonic to both ends (60S) of three equal regions, each of which That was previously defined (60) have been divided Both ends (60S) are at both ends in Machine transverse direction (CD) of the center area (60C). Procedure B is also included. Maximum amplitude output in the middle of the vibration The sonic rate received from the center output section (332A) to the center (60C) is less than the amplitude. At most at the end of the sonic rate vibration that is output from each of the two end output segments (332B) to both ends corresponding (60S) and pre-defined region bonding. (60) with the strength Welded in the middle of the middle (60C) area that has been welded by The intermediate output section (332A) is less than the centered weld strength of each of the two end areas (60S) that were welded by the corresponding two end output sections (332B) (original edit). 1. The manufacturing method of the absorbent product that consists of the first wadding which is made up of It is the front waist band and the second wadding, which make up the back lumbar section. The method consists of step A of transporting the first and second wadding in an overlapping state. Between the anvil and vibrator part, which is provided with the ultrasonic welding device and the B procedure of the pre-determined area welding that has been Provide for the first and second wadding with previously defined spacing in The transport direction of the first and second wadding by outputting the ultrasonic vibration. Sonic from the output part of the vibrator to the pre-defined area, the ultrasonic vibrations that have been induced by the oscillator provided to An ultrasonic attachment whose output part is included. The central output section has been configured to output ultra-vibration. Sonic goes to the middle of three equal regions, each of which is pre-designated. The pages are divided in the transverse direction, the machine cuts the conveying direction, and the two end-output sections are configured to provide vibration output. Ultrasonic to both ends of the three equal regions, each of which has been designated Before has been divided Both ends are at both ends in the transverse direction of the center of the most amplitudes in the middle of the received ultrasonic vibrations. The output from the center-to-center output segment is less than the amplitude at the end of the The ultrasonic vibration is output from each end of the output section to the end. Both the corresponding and the middle bonding strength of the middle area that has been welded by The center output is less than the strength. Are mounted by both corresponding end output sections
