Abstract: The invention relates to a sliding device for a palletizing device for stacking of filled sacks to a sack stacking, comprising a sliding area and a sliding table assembled beneath the sliding area and a slider for sliding of the sacks from the sliding area to the sliding table, wherein the sliding area comprises at least a structure section with a three dimensional surface structure for the reduction of the friction during sliding of the sacks.

Abstract: A process that is faster than conventional processes for manufacturing a film tube from a polymer and/or metal film material includes moving the film tube in relation to the joining tools during the joining process. Before the joining process of the film tube, the metal film material exists in the form of at least one film web. The edges of this film web are joined to one another in a joining process forming at least one longitudinal joint seam. During the joining process the film tube is moved in relation to the joining tools.

Abstract: The present invention relates to a process that is faster than hitherto existing processes for manufacturing a film tube (25, 40, 41, 42) from a polymer and/or metal film material (A-E). The film tube is moved in relation to the joining tools during the joining process. The novelty and inventive step of said process is that before the joining process of the film tube, the metal film material (A-E) exists in the form of at least one film web (A-E). The edges of this film web (A-E) are joined to one another in a joining process forming at least one longitudinal joint seam (27). During the joining process the film tube is moved in relation to the joining tools.

Abstract: A device for the strip-shaped heat sealing or welding of the inner walls composed of a thermoplastic material and lying on top of one another of tube sections that are lying flat is comprised of two heated, longitudinally extending heating jaws, which limit a gap between one another, of means for pressing the tube sections together in one region of the heating jaws, and of a conveyor device that moves the tube sections through the gap. In order to prevent the tube sections from becoming offset relative to their conveyor devices, these means comprise a pair of rolls mounted in the region of the heating jaws, whose rolls form a pressing throughput nip for each tube section.

Abstract: Device for separating stacked flat bag pieces, comprising a supporting structure, which is pivot-mounted in a frame and is provided with a drive, and on which suction rollers can be rotated, whose drive is in a direction of rotation opposite to the supporting structure's direction of rotation. A stacking cassette is positioned in such a manner at the enveloping cylinder, described by the rows of suction elements or suction rollers that each row of suction elements in each roller pulls a bag piece from said cassette. To prevent the trailing side edges of the bag pieces from folding over, the bag pieces are held in the stacking cassette with offset cuts, facing outwardly in the direction of the axis of rotation.
