Abstract: An ultrasonic sealing jaw (1) is used for sealing portions of plastic film to a tube so as to form a sealing engagement of the portions of plastic film around the circumference of the tube. The sealing jaw (1) includes a concave film-tube welding portion (7) for receiving the tube covered by the plastic films the film-tube welding portion (7) to form the film-tube attachment. Adjacent to at least one side of the film-tube welding portion (7) of the sealing jaw (1), is a substantially flat film-film welding portion (3, 4) for engaging the plastic film and sealing adjacent portions of plastic film to each other in an area adjoining the tube. A film-film welding portion (3, 4) defining a top plane (10) of the sealing jaw (1) has at least one recess with a surface (11) so as to form a cavity (12) and forms a cavity (12) with an opening towards the film-tube welding portion (7).

Abstract: A material transfer device for transferring a coating from an outer surface of a transfer tape onto a surface includes a housing; a transfer head around which the transfer tape extends, wherein the transfer head protrudes from the housing; a protective cover connected to the housing and movable between an advanced and a retracted position. The cover has a front end portion adapted to protrude from the housing in the advanced position for protecting an unused portion of the transfer tape when the device is out of use. The connection between the protective cover and the housing is provided by a groove in the protective cover and tongue on the outer surface of the housing.

Abstract: An ultrasonic sealer comprising a hollow shaft (1) having a longitudinal axis (2) and being rotatably arranged in a housing (3) for driven rotation about its longitudinal axis (2). The rotary sealer further comprises a sealing horn (8) arranged coaxially in the hollow shaft (1) and connected to a converter (6) and preferably also a booster (7). The horn (8) is provided with a peripheral sealing area (13) outside an axial end (13) of the hollow shaft (1). The horn (8) is connected to the hollow shaft (1) by means of at least one annular, metallic support (11) extending between an outer face (14) of the horn (8) and an inner face (10) of the hollow shaft (1). The at least one annular support (11) is corrugated in cross section such that at least two grooves and one ridge arranged there between are provided between the inner face (10) of the hollow shaft (1) and the outer face (14) of the horn (8).

Abstract: The refill comprises a base (2) carrying a tubular supply pivot (3) carrying a supply roll (8) of carrier tape carrying adhesive tape, a tubular take-up pivot (4) carrying a take-up roll (12) for spend carrier tape, and an applicator (6) positioned at a front end of the base (2). The supply the applicator (6) and the take-up pivot (4). The carrier tape is extending from a first side of the supply roll (8), to the applicator (6), around the applicator (6), past the other side of the supply roll (8) and to the take-up roll (12) thereby defining a tape area. The base (2) is extending at least at the first side of the supply roll (8) beyond the tape area, and the base (2) is carrying a shielding (7) extending along a part of the first side of the supply roll (8) and a part of a first run (18). Each pivot has an end attached to the base (2) and an opposite free. The refill further comprises a transmission including a slip clutch transmitting a torque from the supply roll (8) to the take-up roll (12).

Abstract: A method for the production of a concrete article having a pattern on a surface thereof, comprising providing a mould having upstanding side walls, and a bottom surface which is patterned with a reverse image of the pattern desired on the surface of the article, introducing into the mould in contact with its patterned surface a first layer of concrete mix by either first introducing a layer of fluid binder slurry in contact with the said surface and applying on top of said slurry layer a layer of aggregate particles, or first introducing a layer of aggregate particles in contact with the said surface and applying on top of said aggregate layer a layer of fluid binder slurry, applying a second layer of concrete mix on top of the first layer, compacting the first and second layers of concrete mix in the mould to form the article in an uncured state, optionally separating the side walls of the mould from the uncured article, and demoulding the article after at least partial curing.

Abstract: The adhesive dispensing product comprises a coherent piece of carrier sheet material with two opposite surfaces, one of which is a first release surface, the piece of carrier sheet material has two opposite lateral side edges. A plurality of individual adhesive segments are present on the first release surface, which adhesive segments each has a circumferential surface, and the circumferential surfaces of adjacent adhesive segments are separated by a distance of at least 0.5 mm. The adhesive segments feature a first adhesiveness relative to the first release surface allowing the adhesive segments to be dispensed from the first release surface. The adhesive dispensing product further comprises a plurality of individual pieces of cover sheet material, which cover sheet material has two opposite surfaces, one of which is a second release surface.

Abstract: Method and apparatus for welding two container walls of plastic film (1, 2) to a plastic tube (3) having a substantially circular cross section, wherein the plastic tube (3) is arranged between two parallelly arranged plastic films (1, 2). The two plastic films (1, 2) are made to extend along the outer surface of the plastic tube (3) and to abut each other along a joint face (7) between two welding jaws (5, 6) in an area (8) adjoining the plastic tube (3). The plastic films (1, 2) are welded by means of welding jaws (5, 6) to the outer face of the plastic tube (3) and welded together in the area (8) adjoining the plastic tube (3). The plastic tube (3) is deformed during welding by means of a compressive force applied by the welding jaws (5, (5) to provide the outer surface of the plastic tube (3) with a substantially plane portion (9) extending on both sides of the joint face (7) and substantially perpendicular thereto.
