Abstract: A sack is formed by first transverse sealing seams from a foil tube, and is provided with at least a first vent channel, which runs largely parallel to the axis of the film tube, and whose inner film layer has first vent openings for venting of the sack interior into the first vent channel. A second vent channel is provided, which is connected to the first vent channel by second vent openings, and which, in turn, has third vent openings, which vent the at least one second vent channel.

Abstract: A method for the production and filling of packaging includes unwinding flattened tubular film material from a roll along a primary axis of symmetry thereof, providing the tubular film material via a welding and separating process with a first lateral welding seam perpendicular relative to the axis, and separating the tubular film material along a separation line to provide a hose section. The hose section open at one side is filled, and the still open other side of the hose section is provided with a second lateral welding seam. Two subsequent separation lines are inserted in the hose section at a distance that is less than the distance between the two edges of the hose.

Abstract: A bottomer for the production of sacks, preferably cross-bottom valve sacks, includes at least one glue unit that applies glue to the components of the sacks. The glue unit includes a nozzle bar, which has at least one nozzle for extruding glue onto the sack components. The glue unit also includes a counter support, which positions the sack components with a force against the nozzle bar.

Abstract: A method for the production and filling of packaging means is described and claimed, in which the following production steps are performed: flattened tubular film material is wound off a roll along the primary axis of symmetry of the hose, the tubular material is provided via a welding and separating process with a first lateral welding seam perpendicular in reference to the tubular axis and separated along a separation line, the hose sections open at one side are filled, the still open end of the hose section open at one side is provided with a second lateral welding seam. It is considered novel and inventive that two subsequent separation lines are inserted in the hose at a distance, which is smaller than the distance between the two edges of the hose. Additionally, a device is described and claimed comprising features allowing the implementation of the method.

Abstract: A forming, filling and sealing machine for producing bags from semifinished products, and for filling and closing the bags, includes a plurality of processing stations. At least two processing stations of at least one first group are successively, largely linearly, arranged in the horizontal plane (x, z) in the transport direction (z) of the bags. The bags or semifinished products are transported between the processing stations by transport devices which generally include gripping devices. The machine also includes at least one second group having at least one processing station that is not linearly arranged behind the first group in the horizontal plane (x, z) in the processing direction (z) of the bags.

Abstract: A machine for forming, filling, and sealing sacks has an unwinding device for a plastic tube, a cross-cutting device that cuts the tube perpendicularly to its principal axis of symmetry and creates tubular pieces in the process, a bottom forming means for forming a sack bottom at one end of the tubular piece, transport equipment to transport the resulting sacks through the machine, a filling station with a feeding element for filling the product in the sack, means of reducing the distance between the product discharge opening of the feed element and the bottom of the sack to be filled, and sealing means to seal the filled sack. The means of reducing the distance is a sack lifting device with which the sack can be lifted in the filling station such that an upper edge of the sack is located above the product discharge opening of the feed element.

Abstract: The invention describes a bottomer for the production of sacks, preferably cross-bottom valve sacks (18), which bottomer comprises at least one glue unit (1) that applies glue to the components (2) of the sacks. The glue unit (1) comprises a nozzle bar (4), which (4) comprises at least one nozzle for extruding glue onto the sack components (2). It should be emphasized that a counter support (5) is provided, which positions the sack components (2) with a force against the nozzle bar (4).

Abstract: (EN) The invention relates to a forming, filling and sealing machine (2) for producing bags (1) from semifinished products (5) and for filling and closing the same, said machines comprising a plurality of processing stations (4, 7, 9, 12). At least two processing stations (4, 7, 9, 12) of at least one first group (3) are successively, largely linearly, arranged in the horizontal plane (x, z) in the transport direction (z) of the bags (1). The bags (1) or semifinished products (5) can be transported between the processing stations (4, 7, 9, 12) by transport means which generally comprise grip means (10, 11, 21, 22). The invention is characterised in that at least one second group (20) of at least one processing station is not linearly arranged behind the first group (3) in the horizontal plane (x, z) in the processing direction (z) of the bags (1).

Abstract: The invention describes a sack (220) which (220) is formed by first transverse sealing seams (110, 150) from a foil tube (101), and which (101) is provided with at least a first vent channel (20), which runs largely parallel to the axis of the film tube (101), and whose inner (40) film layer has first vent openings for venting of the sack interior (210) into the first vent channel (20). It is characteristic that at least a second vent channel (140) is provided, which is connected to the first vent channel (140) by second vent openings (90, 100, 200), and which, in turn, has third vent openings (120), which vent the at least one second vent channel (140).

Abstract: The invention describes a machine for forming, filling and sealing (FFS) sacks (8, 11). As device characteristics, it covers an unwinding device (19) for a plastic tube (15), a cross-cutting device (17) that cuts the tube perpendicularly to its principal axis of symmetry and creates tubular pieces in the process, a bottom forming means (13) for forming a sack bottom at one end of the tubular piece, transport equipment (4, 10, 18) to transport the resulting sacks through the machine, a filling station with a feeding element (2) for filling the product (24) in the sack (8, 11), means (3, 4, 5) of reducing the distance between the product discharge opening of the feed element and the bottom of the sack to be filled as well as sealing means to seal the filled sack.

Abstract: The invention describes a blown film extrusion system (1), which comprises, as its characteristics, a blowing head (5), which extrudes a film tube (9), further a pinch-off device (8), which pinches off the film tube (9), and additionally film guiding elements (7, 13, 27, 28) that guide the film tube (9) between its extrusion by the blowing head and its pinching off. The inventive aspect is that the guiding elements (7, 13, 27, 28) contain a porous, preferably microporous material.

Abstract: Process for setting the temperature of plastic film, which is to be bonded and which exists preferably in the form of slips (8), on collapsed tubular pieces or workpieces (2) made of plastic film, for example valve slips on the raised bottom squares, or bottom cover sheets on the assembled bottoms of block bottom valve sacks,

Abstract: From an adhesive substance application device, correctly formatted adhesive substance applications are applied on a continually conveyed web or on continually conveyed objects by means of a transfer roller that is provided with corresponding format parts. In order to be able to provide the transfer roller in a simple manner with accurately contoured format parts or blocks, the latter are applied or sprayed on the the transfer roller in the form of a hardenable liquid.
