Embodiment Construction

[0120] figure 1 A side view of the mechanism of the belt sealer 100 according to an embodiment of the present invention is schematically shown. Generally, the tape sealer 100 is configured to receive a package 80 containing one or more products to be packaged along the main direction of movement 60 . Package 80 includes pouch neck 82 sealed by tape sealer 100 . To this end, the package 80 is moved relative to the tape sealer 100, typically by being placed on a conveyor belt or other means of transport 71, so that the bag neck 82 of the package 80 is fed into and through the tape sealer 100 on the moving plane 70. .

[0121] Tape sealer 100 may include several components, such as one or more evacuation devices, such as evacuation rollers 120, 120', configured to apply pressure to the packaging material in bag neck 82 so as to remove air from the area of ​​the bag neck to be sealed. Drain, remove or reduce any foreign matter. This generally improves the quality of the seal b...

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.

Description

technical field [0001] The present invention relates to a process and apparatus for sealing packages in packaging applications. In particular, the present invention relates to a composite belt, a belt sealer using the composite belt, and a process and apparatus for tape-sealed packaging in packaging applications. Background technique [0002] Packaging equipment can be used to package products, such as food. Products can be bare or pre-loaded onto pallets. Plastic wrapped tubes can be continuously fed through bag / package forming, filling and sealing equipment. The film and the product are bonded together, eg the product is deposited on the film or the film is wrapped around the product. In some examples, the bare product is fed through a feed belt. A tube is formed around the product by joining together and sealing opposite longitudinal edges of the film. Alternatively, the product is placed in the tube and the leading edge (at the downstream end) of the packaging mater...
