摘要:
The present invention concerns a device and method for reefing a portion of tubular film, the reefing device having at least one reefing finger and at least one drive unit. The drive unit has advancing means, which, for reefing the portion of tubular film, is brought into operative connection with the reefing finger at least at the height of a point of engagement, while enclosing the portion of tubular film, and moves the portion of tubular film in relation to the reefing finger. The device according to the invention and the method according to the invention are distinguished in particular in that the position of the at least one point of engagement can be changed along the reefing finger as reefing progresses or the position of the point of engagement on the reefing finger is changed.

The present invention relates to a method for gathering-up a tubular film portion on at least two gathering fingers of a packaging machine and to a gathering apparatus of a packaging machine for carrying out the method as claimed in the invention. The method is distinguished in that the tubular film portion is expanded at least in a part region when being gathered-up onto the gathering fingers. The gathering apparatus as claimed in the invention is distinguished in that the gathering fingers can be driven into a gathering-up position for gathering-up the tubular film portion, in which gathering-up position the tubular film portion is expanded at least in a part region.

A wrapping device 1 for packaging goods, specifically goods stacked on pallets or the like, with a tube-like film, with a film feeding device 4 with fusion and cutting systems to generate and feed a dome-like film cover within a device frame 6, where film feeding device 4 works in conjunction with a covering device 7 that moves vertically up and down within device frame 6, where covering device 7 is designed to grasp the film cover and place it to cover goods located in the lower segment of device frame 6, is characterized by having film feeding device 4 move vertically within device frame 6. This arrangement simplifies installation, maintenance and repairs, specifically to the film feeding device.

A method and an apparatus for wrapping articles on a pallet, in a foil hood, includes drawing off from a supply, a flat tube formed from two foil webs The webs are folded in an inward direction and directly superposed in a flat state with an integral foil The method includes opening out the end, which is to the fore in the draw off direction of the tube, at least partially sealing the length, pulled off the foil supply, essentially athwart the draw off direction at a position remote from the foremost end of the tube. The method includes cutting off the tube from the remaining foil supply at a position preceding the sealing position, drawing the tube over the articles to be wrapped, after preceding reefing of the hood or of the tube portion eventually forming it on a reefing means The method further includes forming the flat tube, after final draw off from the supply and prior to sealing being so folded inward from its outer sides in a V-shape that the two foil webs are superposed at the outer side during sealing respectively not directly but with the inclusion therebetween of a V-shaped foil fold whose fold tip extends toward the middle of the foil fold.

The present invention relates to a method for at least partially wrapping a piece-goods stack, in which a tubular portion is pulled over the piece-goods stack, and to an apparatus for carrying out the method according to the invention. The method according to the invention is distinguished in particular in that, during the pulling of the tubular portion over the piece-goods stack, pleats are produced in a specific manner in the tubular portion, said pleats extending obliquely over at least one side of the goods stack. The invention is achieved in terms of the apparatus in that the apparatus has a reefing device for reefing and/or drawing over the tubular portion, said reefing device being configured in such a manner that it reefs and/or unreefs regions of the tubular portion at different speeds and/or at different times.
