  • Patent number: 11806986
    Abstract: A flexographic printing device and a method are provided for simultaneously printing at least two material webs having different thicknesses in the printing device. The flexographic printing device includes a printing unit having a printing roller carrying on a surface thereof an image to be printed, an impression roller and an anilox roller adapted to feed printing ink from a printing ink chamber onto a printing cliché mounted on the printing roller. The printing unit is configured for simultaneously printing the material webs having different thicknesses, by adjusting the radial extension of the surface of the printing roller, impression cylinder and/or anilox roller to be adapted to the respective material web to be printed.

  • Patent number: 6699526
    Abstract: A method of making a cutting insert includes forming a powder mixture containing WC, 2-10 wt % Co, 4-12 wt % cubic carbides, adding N in an amount of 0.9-1.7 % of the weight of the cubic carbides, mixing the powder with a pressing agent, milling and spray drying the mixture, compacting and sintering the material at 1300-1500 in an atmosphere of sintering gas 40-60 mbar, applying post-sintering treatment, and applying a coating by CVD or MTCVD.

  • Patent number: RE39894
    Abstract: The present invention relates to a coated cemented carbide insert for turning of steel, like low alloyed steels, carbon steels and tough hardened steels at high cutting speeds. The cemented carbide consists of WC, 2-10 wt. % Co and 4-12 wt. % of cubic carbides of metals from groups 4, 5 or 6 of the periodic table, preferably Ti, Ta and Nb. The Co-binder phase is highly alloyed with W with a CW-ratio of 0.75-0.90. The insert has a binder phase enriched and essentially cubic carbide free surface zone A of a thickness of <20 ?m and along a line C essentially bisecting the edge, in the direction from the edge to the centre of the insert, a binder phase content increases essentially monotonously until it reaches the bulk composition. The binder phase content at the edge is 0.65-0.75 times the binder phase content by volume of the bulk and the depth of the binder phase depletion is 100-300 ?m, preferably 150-250 ?m. The insert is coated with 3-12 ?m columnar TiCN-layer followed by a 2-12 ?m thick Al2O3-layer.
