Abstract:
1. A sub-assembly for a blade for a papermaking machine, the blade having a base adapted to receive a plurality of sub-assemblies, the base having an upper surface, a machine-contacting lower surface and two lateral edges, the sub-assembly having first and second lateral edges and comprising (i) a holder comprising an upper portion, a lower portion, and first and second side surfaces having compatibly inverse configurations; and (ii) a plurality of segments, secured to the upper portion of the holder, each segment having a fabric-contacting upper surface, a holder-contacting lower surface, a leading edge and a trailing edge, and first and second side surfaces each having a preselected profile, such that in a direction from the leading edge to the trailing edge, the profile of each first side surface has a compatibly inverse configuration to the profile of each second side surface; wherein the holder is adapted to be releasably securable at the lower region to the base by a retaining means, in an abutting relation with adjacent ones of the plurality of sub-assemblies, such that the sub-assembly is selectively removable from the base independently of the adjacent sub-assemblies.
