Abstract: An anvil is provided in an ultrasonic sealing machine, in which vibration applying surfaces of a pair of horns and an abutment surface on an end face of the anvil cooperate with each other to bond a laminate. The abutment surface includes left and right welding surfaces which are disposed in the extending direction of the vibration applying surface and protrude toward the horns to face two vibration applying surfaces. The left and right welding surfaces each have an area per unit length in the extending direction, which continuously or step-wisely increases with an increase in distance from a center of the seal area, which is a region where the two vibration applying surfaces are adjacent to each other.

Abstract: An ultrasonic sealing apparatus which allows for easy maintenance of a horn and high cooling efficiency of the horn is provided. The ultrasonic sealing apparatus includes a horn that abuts on a cylindrical material and applies vibration thereto, and a horn cover which includes a small frames that cover a lateral surface of the horn and have slits through which a space in which the horn is enclosed communicates with outside, the horn cover being removably attached independently from the horn.

Abstract: An ultrasonic sealing apparatus for paper packages achieves more stable ultrasonic sealing by cooling the horn during ultrasonic sealing which would otherwise be unstable due to heat imparted to a horn by continuous sealing. An end portion of a horn of a casing that includes the horn and a converter, or the horn, a booster and the converter is cooled by supplying air to a frame portion exposed toward an anvil side.

Abstract: An anvil of an ultrasonic sealing apparatus that includes a horn provided with a strip-shaped vibration applying surface at an end face thereof, the anvil being provided with an abutment surface at an end face thereof, the ultrasonic sealing apparatus sandwiching a laminate of two or more sheets between the vibration applying surface and the abutment surface and melting thermoplastic resin on the sheets by ultrasonic vibration delivered to the vibration applying surface, thereby bonding the laminate. The abutment surface includes a strip-shaped welding surface portion projected toward the horn, and the end face thereof is opposed to the vibration applying surface, and a plurality of block members arranged along the strip-shaped welding surface portion in an extending direction of the welding surface portion without being in contact with each other, and the plurality of block members has a height equal to or lower than the welding surface portion.

Abstract: An ultrasonic sealing anvil is provided which is capable of applying an optimal pressure to an overlap part in the absence of misalignment between the overlap part and the anvil, and preventing application of an excessive pressure in the occurrence of misalignment. An ultrasonic sealing anvil is configured to seal a tubular material having an overlap part extending in one direction, in a sealing direction crossing the overlap part. The anvil is provided with a step that can be abutted with the overlap part R, and a pair of grooves arranged sandwiching the step in the sealing direction.
