  • Publication number: 20230374190
    Abstract: A press cover for a press roll or a transport belt has at least one polyurethane-containing layer. The polyurethane is obtainable by reaction of i) a polyol component, ii) an isocyanate component, and iii) a component containing at least one crosslinker. The polyol component is composed of mutually different structural units having the general formula —O—R1—X—R2—O— in which all of R1 and R2 independently of one another are identical or different and are linear or branched C1-C20 alkylene groups. Groups X are identical or different and are selected from bond, O, C(O)—O, and O—C(O)—O. At least 70 wt % of the structural units meet the following criteria: a) at least 80% of X are O—C(O)—O and the remainder are O or C(O)—O, and b) the average chain length of R1 and R2 is 8 or more carbon atoms, and c) at least 50% of R1 and R2 are independently of one another a linear or branched C8-C12 alkylene group.

  • Patent number: 6932888
    Abstract: A flexible press cover which has an additional strengthening element in at least one of its two end regions. As a result, in the end region, the tensile strength and the tensile rigidity in the circumferential direction are increased with respect to that hitherto known in such a way that it is no longer necessary to clamp the press cover end region in between two components. Instead, the press cover according to the present invention is suitable to be fixed to the outer circumferential surface of a rotatable supporting element belonging to the cover carrying disk without the aid of an outer ring, a clamping band, clamping filament or the like. In the most beneficial case, the arrangement for fixing the press cover to the aforementioned supporting element is completely free of any kind of fixing elements which would be associated with the cover outer surface.
