Abstract: A method for filling packaging including an outer paper packaging member and an inner plastic film bag member with a filling material that is contained in a filling material container arranged above the packaging. The method includes, in the vicinity of the filling material container, forming the plastic film bag member from a tubular film by providing a welded seam along a lower edge. The bag is spread apart at an open upper edge. The plastic film bag member is separated from the tubular film. The plastic film bag member is inserted over the filling material container. The filling material container is lowered together with the plastic film bag member into the outer packaging member. The filling material container is emptied into the plastic film bag member. The material filling container is moved back to a starting position above the packaging.

Abstract: An apparatus for filling and closing sacks or bags, in particular paper side folding sacks, has a plurality of processing stations including a filling station, stationary clamping elements for holding the sack in an open position and a slide cyclically movable between processing stations. Outside grippers are mounted on the slide which are designed to grasp an at least partially filled sack at its side folding by clamping the folding from the outside in said filling station and transporting the sack by means of the slide to the succeeding processing station.

Abstract: In an apparatus for forming, filling and closing packages made of cardboard, cassettes for receiving the package are provided, which may be rearranged in differing processing positions. These cassettes are designed in such a way that they may be either exchanged for one another altogether, or reset for various format sizes. With such a device, format resetting, which has heretofore required considerable retooling times for such devices, may be achieved in a very short time and without great difficulty.

Abstract: An apparatus for separating perforated paper tube sections coming from a paper tube machine consists of a plurality of endless conveyor belts which are disposed above and below the moving paper tube sections. Each conveyor is associated with a plurality of rollers, the rollers above the paper tube section being displaced in relation to those below the paper tube sections. The driving elements for the conveyor belts are located at fixed positions, and to effect separation of the perforated tube sections, the rollers are moved relative to one another for a brief time interval in a direction transverse to the direction of transport of the paper tube sections.

Abstract: For a method of welding multi-layer paper sacks with weldable inner surfaces, the outer layers are folded back from the weldable inner layer during welding. The welding energy reaches the inner layer directly. The welding process is substantially shortened in comparison with known methods, and both the production time and processing time with such paper sacks is reduced.

Abstract: A filling station for filling pleat-sided bags transports such bags in flat form to a filling position. A plurality of spreading members are disposed adjacent the front and rear faces of the bag, and have claws thereon which engage the opposing interior edges of the bag adjacent its openable mouth. The spreading members adjacent each given side of the bag are moved away from one another in a direction substantially parallel to the planes of the front and rear bag faces, and the spreading members on opposite sides of the bag are moved away from one another in directions transverse to said planes thereby to unfold the pleated side faces of the bag and open the mouth of the bag. A filling funnel disposed outside of the bag is moved into the opened mouth of the bag, and bars disposed adjacent the exterior of the several faces of the bag are moved into engagement with those faces to clamp the faces of the bag to the filling funnel during the filling of the bag.
