Abstract (en)
[origin: WO2007098966A1] The invention relates to hard elements generally produced by powder metallurgy for protecting rolling press rollers from wear, this protection taking the form of grid armouring. In order to provide hard elements which can be produced relatively inexpensively and which, in particular, can again be disassembled in a relatively simple manner, even in the damaged state, from their respective roller body cutouts for the purpose of roller repair, the invention proposes prefabricated hard elements (10, 10a, 10b) with a prefabricated central cutout (12, 13, 14) which, starting from the radially inner end of the hard elements, extends over at least some of the height of the hard elements.
