B55283193 "A Bearing Blanket for an Extended Nip Press" ABSTRACT OF THE DISCLOSURE A bearing blanket is disclosed for an extended nip press of a papermaking machine. The blanket (44) includes a base (46) having a first and a second side (48, 50). A first laminate (52) extends along the first side (48) of the base (46), the first laminate (52) having an interface (54) which is disposed contiguous with the first side (48) of the base (46) and a face (56) which cooperates with a hydraul- ically loaded shoe (22) of the extended nip press (12). A second laminate (58) extends along the second side (50) of the base (46) with the second laminate (58) having a surface (60) which is disposed contiguous with the second side (50) of the base (46). The second laminate (58) defines a plurality of recesses (64, 66) for relieving fluid pressure during passage through the nip. The first laminate has a hardness which permits flexing of the first laminate while the second laminate has a hardness such that crushing of the recesses during passage through the extended nip is inhibited.
