Abstract

A form-fill-seal machinehas a pull-down belt mechanism, a vertical sealing mechanism, and a controller. The pull-down belt mechanism conveys a cylindrical film Fm. The vertical sealing mechanism applies pressure and ultrasonic oscillation to the cylindrical film which is conveyed by the pull-down belt mechanism, and seals the cylindrical film. The controller controls the pull-down belt mechanism, and the pressure and the amplitude of the ultrasonic oscillation applied to the cylindrical film by the vertical sealing mechanism. The controller applies pressure and ultrasonic oscillation to the cylindrical film immediately before reaching a first point in time when the cylindrical film begins to be conveyed. The controller changes at least one of the pressure and the amplitude of the ultrasonic oscillation applied to the film according to the speed of the film in a time period after reaching the first point in time.
