    Abstract: A film roll supporting device comprises a shaft body part, a shaft tip part, and a projection part. The shaft body part extends through a central hole of a film roll and having the film roll mounted thereon. The shaft tip part extends in an axis direction of a shaft from one end of the shaft body part on a side to be inserted into the central hole of the film roll. The projection part extends in a direction intersecting the axis direction of the shaft body part from the shaft tip part. The projection part abuts from below to a core of the film roll provisionally placed on the shaft tip part when the mounting of the film roll is performed. A cutout recessed in a direction intersecting the axis direction of the shaft body part is formed in the projection part.

    Abstract: An ultrasonic sealing unit is equipped with a converter, a horn, a fixing member, and a retaining member. The converter generates ultrasonic waves from an electrical signal. The horn vibrates because of the ultrasonic waves generated by the converter. The fixing member is a member for fixing the ultrasonic sealing unit. The retaining member is a member for retaining the ultrasonic sealing unit in a position different from the position where the ultrasonic sealing unit is fixed by the fixing member. The ultrasonic sealing unit may reduce vibration transmitted to the surroundings.

    Abstract: A bag making and packaging machine has pull-down belt mechanisms, a transverse sealing mechanism, a rotatable folding member, and a gas blowing mechanism. The folding member, before the transverse sealing mechanism, seals a cylindrical film, pushes against a side portion of the cylindrical film to thereby fold the cylindrical film inward and form a fold in the cylindrical film. The gas blowing mechanism blows a gas onto the fold to thereby inhibit the cylindrical film from sticking to the rotating folding member.
