Abstract: A method and an apparatus for wrapping a stack (12, 13) of superposed sheets, brochures and/or folders with a wrapping sheet (15). The stack (13) is travelling in a first direction (4) on a first conveyor (2) defining a conveying path. A supply of wrapping sheets (14) is placed in line with the first conveyor (2). At the downstream end of the first conveyor (2) a rotating waver wheel (10) is arranged. This waver wheel pulls a top sheet (15) from the supply of wrapping sheets (14) and turns the wrapping sheet (15). Downstream of the first conveyor (2) a second conveyor (3) is provided defining a gap (5) between the first and second conveyors in which the wrapping sheet is inserted. As the stack (13) engages the wrapping sheet (15), the rotating waver wheel (10) folds the sheet around the stack.

Abstract: In connection with the packaging of items or loose material in sheet packings it is known to use a web of cohering flat bag members, which is successively conveyed to a filling station, in which the bag members are opened, one by one, for filling and subsequent closing and separation from the web. The free mouth edges of the bag members or the web are profiled for supported conveyance on opposed carrier rods, tubes or gripping chains which, just before the filling station, diverge from each other for effecting opening of the bag members. The invention provides for a flat bag web, the upright edge strip portions of which are caused to be folded down over respective opposed carrier chains.

Abstract: Methods are known for conveying bags in the form of a continuous web such that they open at a suitable place during continuous conveyance and during maintenance of the open condition so they can be filled and sealed after closing. Prior art methods utilize complicated methods for retention. According to the invention, the bag web is suspended on horizontal studs mounted on carrier chains running in such a way that the bags open and a surrounding groove around the studs along the chains prevents the bags from falling off during passage of filling stations etc.

Abstract: The present invention relates to a method and an apparatus for wrapping bundles of printed matter by placing a folded film sheet around such bundles when these are conveyed to and through a wrapping station. The apparatus includes a lower, through-going belt conveyor with mutually separated conveyor straps and a couple of overhead band conveyors in line with each other creating a transverse gap between them. Below the spaces between the lower conveyor straps and just below the gap a transverse row of compressed air nozzles directed upwards is arranged.

Abstract: The present invention concerns a device, an arrangement and a method for opening or separating two closely joined sheets of flexible material, e.g. sheet pieces and folded pieces of film or paper, by applying vacuum on the opposite outer sides of these joined sheets. Typically, the case is opening different packing wrappers or large bags or envelopes, which are to be opened for receiving inserts, e.g. diverse advertisement prints, and which are to be handled with great reliability and rather large capacity, e.g. 5,000 to 25,000 pcs. per hour.
