A first film can be conveyed through a horizontal form-fill-seal machine that contains tooling stations in which bottom sealer bars are positioned in different tooling stations relative to side sealer bars. The first film can be processed by the machine to form a first pouch. After the first pouch is formed, a vertical height of one or more of the side sealer bars and/or one or more of the bottom sealer bars can be selectively adjusted. The same bottom and side sealer bars remain in the machine during the selective adjusting of the vertical height. After the selective adjusting of the vertical height of the component, a second film can be conveyed through the horizontal form-fill-seal machine. The second film can be processed by the machine to form a second pouch having at least one dimension that is different than the first pouch.

A method and device for sealing gas in a gas compartment-equipped bag, in which pressurized gas discharge outlets are provided in the distal ends of a horn and an anvil of an ultrasonic sealing device, and such horn and anvil used for ultrasonic sealing are also used as gas-discharging nozzles. The distal ends of the horn and the anvil are placed against a cutout of a gas compartment of a bag, a gas is discharged into the gas compartment from the discharge outlets, the films surrounding the cutout are being clamped by the horn and the anvil while gas discharging is in progress, and then the gas compartment is ultrasonically sealed by the horn and the anvil to trap the gas inside.

Method and apparatus for joining at least two plastic parts.

A method for joining at least two plastic parts (1, 5) along a predeterminable common joining point using infrared radiation (IR), is characterized in that each of the plastic parts (1, 5) to be joined is heated using infrared radiation at least along the joint by means of an assignable radiation source without touching the respective other plastic part (1, 5), that the respective one radiation source is operated independently and spatially separated from at least one further radiation source, that the radiation sources emit their respective infrared radiation to the respective assignable plastic part (1, 5) without contact and following the contour of the joint, and that the degree of heating by means of the respective infrared radiation is selected such that the joint is formed when the plastic parts (1, 5) are brought together.

A transfer device of a bag processor includes a rail member which defines a transfer route and a plurality of movable gripper pairs. At various processing stations on the transfer route, time for executing a particular process may differ. The number of bags processed at each processing station and transfer states of the bags is controlled to ensure that a number of processed bags is equal. Bags on which first process has been executed are stocked on an upstream side of the second processing station.

A bagging and packaging machine includes a transport mechanism and a plurality of processing units. The transport mechanism transports a pouch in a standing posture, along a predetermined track. The processing units process the pouch transported by the transport mechanism. The processing units include a filling unit that fills the pouch with an object to be packaged. The transport mechanism has a holding unit that holds the pouch, and a swinging mechanism that swings the pouch, which has been filled with the object to be packaged in the filling unit, in a vertical plane parallel to a transport direction.
