摘要： 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. These strip portions are prepared with a row of perforations which, by the said down-folding, are moved down into holding contact with holding pins upwardly projecting from the carrier chains, whereby a very safe carrying and conveying engagement is obtained without any special profilation of the mouth edges and with a simple design of the carrier chains.
