Abstract: The invention is a device for welding two overlapping film sections situated on one side of a goods stack. The device includes a welding bar with a welding surface oriented in the direction of the film sections to be welded. The spacing between the welding bar and the film sections is reducible. The welding surface is elastically deformable into a concave course and/or to a convex course between its two ends. At least one displacing device adjusts the course of the welding surface to a concave and/or to a convex course. The displacing device displaces welding bar. A control unit of the welding bar individually controllable, such that the curvature of the welding bar is adjustable to the contour of the side of the goods stack in the region of the film sections to be welded with one another for the subsequent welding of the overlapping film sections.

Abstract: A device for inserting an aperture in a film wrapping of a goods stack arranged on a pallet, where the film wrapping is a film hood drawn over the goods stack or as a film sleeve surrounding the goods stack is disclosed. A piercing element has a rotatably attached actuation arm. The piercing element exhibits first and second part-regions. The first part-region is mounted rotatably on the actuation arm and the second part-region includes the piercing region. The second part-region is pivotable relative to the first part-region from an original position against a restoring force. A corresponding system and a method for inserting an aperture in a part-region of a film wrapping of a goods stack arranged on a pallet is disclosed, where the film wrapping is configured as a film hood drawn over the goods stack or as a film sleeve surrounding the goods stack.

Abstract: A method for creating an opening in a sheath, made of stretch film, that retains a goods stack arranged on a pallet. The pallet comprising an upper-side deck surface as support for the goods stack and lower-side support feet. The sheath engages under the support feet arranged in the region of the four outer edges of the pallet. At least one opening is in the sheath between two support feet . At least one opening is generated such that the sheath is first heated, the heated sheath is retracted from the pallet and then, still in the heated state, displaced upward. The upwardly displaced sheath is secured in its upwardly displaced position by cooling. The invention also relates to a shaping apparatus, and additionally to at least one heating device for carrying out the method.

Abstract: A method for creating at least one clearance in a sheathing consists of shrink film and secures a stack of items arranged on a pallet. The pallet has a top standing surface for the stack of items and a plurality of spaced bottom legs forming leg clearances. The sheathing engages under the legs in the region of the four outer edges of the pallet. At least one clearance is introduced into the sheathing region located between two legs. At least one clearance is intended to be created such that the sheathing region is first of all pulled away from the pallet in the still-hot state and is subsequently displaced upwards in the still-hot state, wherein the upwardly displaced sheathing region is then fixed in its upwardly displaced position by cooling. The invention also relates to a shaping apparatus for carrying out the method.

Abstract: A method is disclosed for transferring a film, preferably a wound-on stretch film, wound onto a winding mandrel, oriented in particular vertically and preferably supported exclusively in the region of its upper end, of an unwrapping apparatus, such that when the transfer position of the winding mandrel is reached, the film wound onto the winding mandrel is pulled off the winding mandrel by means of at least one transfer device and delivered to a disposal area. An apparatus for transferring a film, preferably a wound-on stretch film, wound onto a winding mandrel, oriented in particular vertically and preferably supported exclusively in the region of its upper end, of an unwrapping apparatus, is disclosed. The apparatus encompasses at least one transfer device for pulling off the film wound onto the winding mandrel when the transfer position of the winding mandrel is reached.

Abstract: An apparatus for wrapping a stack of objects vertical side faces and a horizontal top face has a unit for wrapping a film wrapper around the stack such that respective sections of the wrapper extend upward from each of the side faces. A first welder welds ends the film wrapper together at one of the side faces of the stack. A fold-over device folding the film sections over onto the top face of the stack. A second welder welds the folded-over film sections together on the top face of the stack.

Abstract: An apparatus for wrapping a film around each of a sequence of objects passing sequentially through a wrapping station has a supply of the film adjacent the station, a feed head at the station having a base, a support carried on the base and rotatable relative thereto about a vertical axis, and a feeder on the base for pulling the film off the supply and feeding it to the support. A film storer carried on the support is operable to take in and store a length of film fed to the support by the feeder. A pull-down device in the station is vertically displaceable below the feed head.

Abstract: An apparatus for wrapping a stack of objects vertical side faces and a horizontal top face has a unit for wrapping a film wrapper around the stack such that respective sections of the wrapper extend upward from each of the side faces. A first welder welds ends the film wrapper together at one of the side faces of the stack. A fold-over device folding the film sections over onto the top face of the stack. A second welder welds the folded-over film sections together on the top face of the stack.

Abstract: The invention relates to a method for drawing a tubular film (1) over a stack of goods (2), wherein the tubular film is first gathered on a gathering device (R/Ü). The gathered tubular film is then drawn over the stack of goods using a covering device, in that the covering device is moved along the stack of goods and the tubular film is thereby ungathered. After reaching an end region of the stack of goods, the covering device is moved along a segment of the stack of goods (?) opposite the covering direction, so that a first tubular film segment (15) is laid on the tubular film already contacting the stack of goods. The covering device is then moved along at least part of the segment of the stack of goods in the covering direction again, so that a second tubular film segment (16) is laid on the first tubular film segment.
