Abstract: A waterless-toilet liner has a seat panel adapted to lie atop a waterless-toilet seat and formed with a central hole of a size and shape generally corresponding to a size and shape of the hole of the seat, and a bag having an upper rim secured to the seat panel around the hole therein. This liner is made by first advancing a foil tube to a first work station and forming a cross-seam and cut in the foil tube-to cut therefrom a bag having an open end. Then the open end of the bag is fitted between a pair of foil sheet. An opening is cut through the foil sheets and open end of the bag and the edges of the bag at the opening and there adjacent are bonded to the foil sheets. Then the foil sheets are cut through or perforated downstream of the bag.

Abstract: The invention relates to a bag-stack and a device for the production of bag-stacks, in particular bags for automated machines, wherein the bag stack is formed from a plurality of connected bags made of plastic foil, and wherein each bag is formed from a front wall and a back wall. The back wall is built longer than the front wall in the area of an opening. The bag stack is welded at the back wall to the longer end of the front wall, wherein the bag-stack exhibits at least three welds, distributed over the width of the bag stack at the longer end of the back wall in such a way that a sturdy edge of the bag-stack is formed.

Abstract: A bag has front and back thermoplastic panels having upper and lower end edges and joined-together longitudinal edges. A C-shaped thermoplastic handle has a central part extending transversely parallel to one of the end edges of the front panel and a pair of end parts extending transversely inward toward each other from outer ends of the central part and bearing directly against a face of the front panel. Respective strong welds secure each of the end parts to the face of the front panel at a spacing from the outer end of the respective central part.

Abstract: Devices for cross-welding or cross-separating welding plastic films (2) are used in a manner known per se in machines for producing bags, said devices comprising a welding roller (3) and a heated welder terminal (4) which can be moved reciprocally and between which the plastic films (2) are guided for welding. According to the invention, the welding roller (3) is covered by a continuous belt (5).

Abstract: Foil bags are formed as new paper bags by fusing together two webs and tying a detachable strap which has a suspension opening to one said opening of each bag, the strap being separated by a perforation line from the respective side of the bag. A pocket is formed at the end of the bag opposite the insertion opening and can have a flap provided with an adhesive strip covered by a masking layer.

Abstract: A stack of plastic foil bags has a flap projecting beyond a filling opening on one broad side of the each bag which has a corner region delimited by perforations and formed in the corner region with at least one interlocking point for joining the bags in the stack and a stack-incorporation means separate from the interlocking point and enabling assembly of the bags into the stack.

Abstract: Stack consisting of a multiplicity of bags which are connected to one another and are made of plastic film, in particular vending machine bags, and also process and apparatus for producing and filling bags of this type The invention concerns a stack consisting of a multiplicity of bags which are connected to one another and are made of plastic film, in particular vending machine bags, and also a process and apparatus for producing and filling bags of this type which, for the purpose of simple production and handling when filling with a product, such as, for example, a loaf of bread or the like, have perforation lines (9, 9′) which run at an angle with respect to the filling opening (6) in order to form corner sections (11) with interconnecting points (12) provided in them, and which, when filling, can be severed cleanly from the bag stack and taken for packaging with a nice-looking exterior.

Abstract: A bag-making method and apparatus in which the synthetic resin film web, folded to provide a double-layer is passed on a lower suction belt conveyor continuously through a weld station in which a plurality of separating weld elements at a right angle to the web weld respective seams and separate respective bags from the web. The conveyor is advanced with a stroke which is equal to the number of such elements times the bag width. A multi-belt suction conveyor above the lower conveyor picks up the bags and transfers them to a pin-collecting conveyor on which stacks of the bags are formed and on which pads can be produced from the stacks for transfer by a robot arm into packing cartons.

Abstract: A method of making multiwall plastic bags wherein half-width foil webs are unwound from respective rolls below a segment of a path within which a multilayer full-width web is guided. The half-width webs can be slit and unfolded or simply unfolded to form full-width single-layer webs which are combined by superimposition to form the multilayer full-width web. The latter is folded and the folded multilayer width is formed into the bags.

Abstract: A stack of flexible bags oriented horizontally in a stack station is packaged by first sliding a robot hand horizontally into position around an end portion of the stack with front and rear grabs of the hand aligned with edges of the end portion and another portion of the stack wholly outside the hand. Then the grabs are closed on the edges of the end portion with the front grab positioned inward of the stack from the back grab and the hand is raised and pivoted about a horizontal axis to fold the gripped stack about a fold line adjacent the front grab and to one side of which lies the gripped portion and to the other side of which lies the other portion so that the bag is given a downwardly open U-shape. The back grab is then released and reengaged around the folded stack to press the other portion against the end portion still gripped by the front grab.

Abstract: A method of packaging plastic bags, particularly bags for automated machines, in stacks held together by wire brackets in a transport container such as a cardboard box. For the purpose of simple and speedy handling, the bag stacks are deposited in the transport container with outwardly pointing wire bracket legs, so that the bag packages can be deposited in the cardboard enclosure and removed from the same without problems, preferably automatically.

Abstract: A method of and an apparatus for producing stacks of bags where, instead of connecting the position of the foil web, a marking on the foil web is detected and used to correct the positions of the devices which operate on the web. These devices can include a cutter for removing a strip from the upper layer of the flattened blown tubular web, the punch for punching holes in the lower layer, and the device for infolding are among the devices controlled in response to the marking. The latter can be printed on the web as it is unrolled or formed during the extrusion or foil blowing process.
