Abstract: A packaging apparatus includes a frame, a lower tool engaged with the frame and configured to receive one or more supports, and an upper tool configured to engage a film portion with at least one support. The lower tool is movable relative to the frame at least between: a packaging position, in which the lower tool is aligned with the upper tool, and a loading position spaced from the packaging position in which the lower tool is configured to receive said support. The packaging apparatus comprises a barrier configured to intercept the package during the movement of the lower tool from the packaging position to the loading position.

Abstract: A composite belt assembly for a band sealer is provided. The composite belt assembly comprises a belt comprising a main belt; a first layer; and a second layer; wherein the first layer is arranged in contact with the main belt, preferably between the second layer and the main belt; and the first layer includes an attachment portion, configured to contact the main belt and the second layer. There is also provided a band sealer comprising a composite belt assembly and a packaging line comprising the band sealer. There is further provided a method for heat sealing a package, comprising providing a composite belt assembly, gripping a bag neck of the package using the composite belt assembly, guiding the bag neck of the package along a movement plane using the composite belt assembly providing a sealing element configured for heat sealing a plastic material of the bag neck, and applying heat to at least part of the bag neck through the first layer of the composite belt assembly using the sealing element.

Abstract: An evacuation station has a first chamber, a second chamber, and a dividing wall separating the first and second chambers. The dividing wall has a gap fluidly coupling the first and second chambers. The second chamber is fluidly coupled to a vacuum source. A package is made from a film and is arranged in the evacuation station. An inner volume of the package is in fluid communication with an inner volume of the second chamber via the open end. A control unit controls a pressure differential between a first internal pressure in the first chamber and a second internal pressure in the second chamber to cause aspiration of gas from the inner volume of the package.

Abstract: The filling device houses a compressor which is connected via a suction line comprising an inlet shut-off valve to a source of gaseous fuel, and is adapted to be connected to a gaseous-fuel container via a supply line equipped with a pressure-limiting valve and a discharge valve. The inlet valve and the discharge valve are connected to a control device which together with the pressure-limiting valve, the discharge valve and, if required, the inlet valve is disposed in a pressure-resistant casing connected to a discharge line leading away from the device. The control device is adapted to be influenced in dependence on control signals from a temperature sensor detecting the environmental temperature, a pressure sensor detecting the pressure at which the compressor is supplied, and a pressure-difference sensor disposed in front of the inlet valve and detecting the difference between the pressure in the suction line and in the casing.
