Abstract: The displacement mechanism includes: an urging mechanism that urges an anvil roller toward an ultrasonic horn in such a manner that output surfaces and a welding surface move closer in the normal direction thereof; and a pressed member that has guide surfaces against which the outer surface of the anvil roller, positioned within non-welding areas, are pressed by an urging force of the urging mechanism, the pressed member being fixed to a sheet holding roller in a state where a pressed surface is disposed within the width-direction range of a slit. In response to the movement of the anvil roller from a welding area to the non-welding areas, the guide surfaces of the pressed member guide the anvil roller in a direction in which the output surfaces and the welding surface move away from each other.

Abstract: Provided is an ultrasonic horn, the output amplitude of which can be significantly increased. An ultrasonic horn includes an input-side end section that has an input surface that receives ultrasonic vibration, and an output-side end section having an output surface that outputs ultrasonic vibration to a sheet. The output-side end section has a dimension, in the length direction, over which a side edge portion of a front abdominal section and a side edge portion of a rear dorsal section can be welded in the longitudinal direction, and is branched in a width direction that is perpendicular to the length direction by a slit that extends in the length direction. A pair of surfaces of the output-side end section, positioned on both sides of the slit, functions as the output surface through which the ultrasonic vibration is output.

Abstract: A sheet conveyance device for conveying, along a conveyance path, a sheet in which a given region from an obverse surface toward a reverse side thereof is composed of a non-woven fabric, and a powder supply device for supplying a powder to at least a partial zone of the sheet, are provided. Further, a fiber-raising device for raising fibers in at least part of the powder supply zone of the sheet is provided on the conveyance path at a position upstream of the powder supply device in a conveyance direction of the sheet.

Abstract: An ultrasonic welding device includes a rotary support mechanical assembly rotatable about a rotation axis and operable to support a sheet over a circumference centered on the rotation axis, the sheet being continuously supplied; a horn and an anvil attached to the rotary support mechanical assembly to thereby revolve about the rotation axis and sandwich the sheet supported over the rotary support mechanical assembly to weld the sheet; a cam drum and a cam follower for driving the anvil in such a manner that the anvil moves relative to the horn; a holding member body; and a power transmission mechanism for distributing a power generated by the cam and the cam follower in such a manner the power is transmitted to the anvil and holding member body in opposite directions.
