Abstract:
A fully automated plasma sheet metal cutter that can be integrated into a HVAC coil-line and which increases the precision of cutting, decreases the time it takes to cut a particular component sheet metal part, and offers flexibility in cutting different sized and shaped holes or openings. Further, since the system is fully automated, it eliminates the error or cost attributed to a portion of the cutting process that heretofore has been associated with a manual laborer.
Abstract:
There is provided a printed board machining apparatus that limits less in terms of the length of printed boards to be machined, that can be readily controlled in positioning a sheet-like workpiece and that is capable of improving the machining efficiency. A plural sets of optical scanners and fθ lenses that compose laser condensing and positioning means are disposed apart in a width direction (X direction) orthogonal to a longitudinal direction (Y direction) of the sheet-like workpiece and two sheet-like workpieces are fixed on a machining table in parallel in the width direction to machine printed boards on the sheet-like workpieces. The disposition of the fθ lenses allows the machining of the plurality of lengthy printed boards to be completed practically in the same time or in the same time without limiting the length of the printed boards to be machined.
Abstract:
In a web processing device, a marking head is disposed so as to oppose an X-ray film which is trained about a print roller which is at an upstream side of slitting blades. Within a scanning range of a laser beam of a marking head, two printing regions are disposed with a non-printing region therebetween. The non-printing region is disposed so as to oppose a cutting line which is cut by the slitting blades. Before cutting the X-ray film, the web processing device forms marking patterns on both sides of the cutting line.
Abstract:
The invention concerns a method for overlapping welding of two coated metal sheets (1, 2) with a beam of high energy density (11), characterized in that it consists in splitting the beam (11) into a first sub-beam (12) passing through both coated metal sheets (1, 2) and forming in said zone a first molten metal bath (18) and into a non-through second sub-beam (13) forming a second molten metal bath (19) whereof the depth is less than the thickness of the upper coated metal sheet (1) and overlapping at least part of the first molten metal bath (18) for promoting evacuation of vapour from the coating material and directing on the second molten metal bath (19) a neutral gas jet with high ejection speed to form at the surface of the second molten metal bath a sink (22).
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:
Method for joining components of metals and alloys, particularly components of light metals, including alloys of light metals and possibly hybrids/composites containing light metals. Oxide on the surfaces to be joined is removed immediately prior to joining, and the groove is filled with a metallic filler material by means of extrusion while the supply of oxygen to the groove is restricted. The invention is also directed to a device for conducting the method, which may optionally include means for heating, means for measurement of temperature and pressure during extrusion as well as controlling means for automation of the joining process.
