Definitions
- the invention relates to a method and an apparatus for Wrapping a good with a plastic film, the Driving in or out of the film well against a film curtain is enclosed on several sides and in the import area next to the goods a first and a second film curtain part remains and a intermediate film middle part of the goods on one or more sides encloses.
- a closer is provided, which the Afterwards, the import area is at least almost completely closed, wherein at least one of the two film curtain parts by one Clamping device is tensioned so that the thing lying around Foil middle part fits tightly.
- the closer positions here the two film curtain parts such that these by a Sealing unit to be welded together and each severed ends of the film middle part welded together to then hand out the finished goods.
- the aforementioned methods and devices are used, for example previously grouped goods, for example with a plastic skin film to connect firmly to one another to make bigger solid unit of goods.
- a stack of boxes is piled up that by the above-described method and the device be firmly connected, if so Individual boxes are required to separate the plastic film is.
- a clamping device in front of one Welding the film to the goods tightens them. It becomes Example two oppositely driven rollers are used, each roller being provided for a film curtain part. The film material is transported back by the opposite movement and thus tightened or stretched the film. After the film middle part lies tightly against the good, the Sealing unit used, on the one hand the foil curtain severed, the ends of the film middle part welded together and at the same time or shortly afterwards the two, well separate foil curtain parts reconnects in order for that next following good again a closed film curtain To make available.
- the number of cycles of the known devices and those equipped with them The process is determined by the individual periods, which is the sequential sequence of the aforementioned packaging steps required.
