A device for stacking flat, deformable, items contains a transfer device that accommodates individual items conveyed to it in receptacles and conveys them to a serializing device. At that transfer device, a row of compartments, into which the items are inserted, is conveyed transversely to the direction along which items' arrive. During insertion, items receive a velocity component in the compartments' direction of motion, while being brought to a standstill along their original direction of motion by one or the other of their flat sides coming into contact with a compartment wall, or an item that had been previously inserted into the compartment, in order that the compressive forces, and thus the deforming forces, exerted on the items will be slight.

Stacker

An apparatus and a method for packaging articles in bags is proposed, where a packaging magazine is used for receiving and guiding an article to be packaged. An article to be packaged is slid by a slider into the packaging magazine. The packaging magazine then moves together therewith into an opened bag, which is removed from a bag stack. With the bag, which surrounds the packaging magazine, the latter is then slid into the transfer magazine from where further conveying takes place.

Method and apparatus for the packaging of articles

An apparatus for the supply of bags formed into stacks to a point where in each case the top bag of the stack is to be opened, contains two parallel conveyors, e.g. in the form of revolving chains, which are synchronously driven. The stacks are held together by two holding members. The holding members are so inserted with a widened foot in the holders of the conveyor that they can be slid out of the holders again through a stop member. These holders have a small mutual spacing, so that the stacks of bags can be juxtaposed on the apparatus with a small reciprocal spacing.

Apparatus for the supply of bags

An apparatus for packing articles contains successively in a conveying direction a feed station, where the articles to be packed are fed into the installation, a station for opening the pack and a station for sealing the filled pack. The two stations, optionally also a compressing station, are successively located on rails, to which they can be fixed in random positions. Consequently it is possible to modify the mutual spacings of the stations and the absolute positions of the stations. This makes it possible to adapt the apparatus to different pack sizes, different articles to be packed and further differing circumstances, whilst still allowing short conveying paths.
