    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: A ultrasonic sealing anvil has a strip-shaped pressing surface that faces a vibration applying surface of an end of a horn and extends along a welding position of sheet members, the pressing surface having a step and a pair of extending surfaces, the step having a concave shape formed at a position at which the step abuts a thick layer portion with a relatively large thickness of the laminated sheet members and having inclined surfaces on both left and right sides, the pair of extending surfaces being continuous to the respective inclined surfaces on the both left and right sides of the step and extending leftward and rightward along the welding position with the step interposed therebetween, wherein the inclined surface has one or more grooves that extend in a width direction of the pressing surface.
