PCT No. PCT/GB93/00718 Sec. 371 Date Dec. 9, 1993 Sec. 102(e) Date Dec. 9, 1993 PCT Filed Apr. 6, 1993 PCT Pub. No. WO93/21380 PCT Pub. Date Oct. 28, 1993.A mounting assembly for a scraper blade or cutting blade includes two retaining devices for retaining a first part of the blade therebetween. An operational part of the blade extends from the retaining devices to scrape debris from a roll. One of the retaining devices is a plate made up of a plurality of fibrous layers arranged to provide predetermined strength to the blade in a first direction while allowing flexing of the blade in a second perpendicular direction. The fibrous layers are primarily of woven or laid glass but these layers can also include carbon, ceramic, polyester or aramid fibers. These fibers or monofilament reinforced laminations are encapsulated and bonded in a thermosetting resin to provide desired operational properties.
