Abstract:
A system and method of forming a continuous strip from a plurality of strips, each strip having a leading end and a trailing end. Embodiments can include a forming apparatus that chamfers at least one of the leading and trailing ends of each strip. The chamfered trailing ends may then be positioned against chamfered leading ends of successive ones of the plurality of strips. Once a leading end and a trailing end are positioned against one another, a first welding apparatus may weld on a first side, from above, the trailing and leading ends positioned against each other to form weld joints. Once at least two strips have been welded together, the strips can constitute the continuous strip. An inverting apparatus can then invert the continuous strip and weld joints. The inversion of the weld joints can be done so as not to create a reverse bend in the continuous strip. A second welding apparatus can then weld on a second side opposite the first side, from above, the inverted weld joints to form weld junctions. A pipe forming apparatus can form a pipe using the continuous strip, wherein the successively welded-together strips can be continuously or semi-continuously supplied to the pipe forming apparatus to form the pipe.
Abstract:
The invention relates to a method for processing a continuous metal band (10) provided with two predominantly radially oriented main surfaces (15) and with two predominantly axially oriented side faces (11), in particular for shaping the said side faces (11) thereof, which method includes the step of melting and subsequently allowing to solidify an axially lateral edge part of the band (10), at least including a part of a respective side face (11).
Abstract:
Vorrichtung zum Schweißen von Bändern (2) mit einer Schneidevorrichtung (10) zum Schneiden der Bänder (2) und mehreren Fixationsmitteln (16) zum Halten der Bänder, wobei die Vorrichtung zur Verbesserung der Schnittqualität Niederhalter umfasst, die das Band benachbart zur Schneidevorrichtung (10) fixieren.
Abstract:
This vertical packager comprises a packing sheet (2) marking mechanism (3), along the path of said packing sheet (2) from the reel (21) towards the cutting, filling, and package sealing sections (11) . Said mechanism (3) includes a laser beam generator that upon application to the packing sheet (2) creates a tear line (9) of varying adjustable shapes and depths and systems for focussing of the laser beam onto the packing sheet (2), a housing mounted on movable guide sections of the focussing system, a protective casing, ventilation apparatus for the removal of smoke created and a control system for movement of the housing and for the operation of the laser beam generator.
Abstract:
Zur Erzeugung von Streckmaterial aus einer folienartigen Materialbahn (4), insbesondere Metallbahn, werden in der Materialbahn (4) mit Hilfe wenigstens einer Schneideinheit (5) mit Hilfe von Laser-, Wasser- oder Elektronenstrahlen Schnitte (2) angebracht, wonach die Materialbahn (4) mit Hilfe einer Streckeinrichtung (28) einer Streckung unterworfen wird; die Schnitte in der Materialbahn (4) werden unter Führen der Schneideinheit (5) quer zur Längs- bzw. Tansportrichtung (7) der Materialbahn (4) als Querschnitte (2), gemäß Querlinien (3) quer zur Längs- bzw. Transportrichtung (7), angebracht.
Abstract:
A laser cutting device (5), comprising a material feeding means (A) for feeding a sheet-like material (11) in a feeding direction, a processing head (B) capable of radiating laser beam toward the material, a head moving means (C) for moving the processing head in a material feeding direction X and a material lateral direction Y, an upstream side support means (belt conveyor mechanism F) for supporting the material on the upstream side of the lower part of the processing head and increasing/decreasing the support area (R2) of the material in the feeding direction according to the movement of the processing head in the feeding direction, and a downstream side support means (belt conveyor mechanism E) for supporting a part cut on the processing side of the lower part of the processing head and increasing/decreasing the support area (R1) of the cut part in the feeding direction according to the movement of the processing head in the feeding direction.
Abstract:
A method in the manufacture of a web-shaped packaging laminate (22) comprising a core layer (24) of paper or paperboard, the method including the steps of coating (38) a first side of a material web (40) of paper or paperboard with an outer layer (26) of thermoplastic material, an thereafter forming, with the aid of laser burning (46, 48) on the thus thermo-plastic coated first side of the packaging laminate (22), a perforation line (32) through said thermoplastic layer (26) and said core layer (24). After said coating (38) with the thermoplastic material but before the formation of the perforation line, the packaging laminate (22) is compressed (44, 10) on said first side for the formation of a compression line (30) in which said core layer (24) is compressed, whereafter said perforation line (32) is formed in said compression line (30). The present invention also relates to a plant in the manufacture of the packaging laminate, as well as the thus produced packaging laminate (22).
Abstract:
The invention relates to an interconnection between two overlapping end sections of metallic strips (10, 20) in which a quick and economical interconnection should be produced. To this end, the invention provides that several annular welds (30) are provided in the overlapping area (15) which are situated at a distance from the face ends of both strips (10, 20).
