摘要

15943-001 PATENT APPLICATION IMPROVED METHOD AND APPARATUS FOR PRODUCING HIGH ABRASION RESISTANCE SURFACE SHEETS, AND SHEETS PRODUCED THEREBY Surface sheets (230) impregnated with thermosetting resin and including a layer of abrasion-resistant particles are produced by the disclosed process. The process includes a method of applying the abrasionresistant particles by spraying a slurry of such particles onto the surface of a web (158) by means of a rotary head (138) and a plurality of spray pistols (136). The step of spraying the slurry onto the surface of the web occurs after a first impregnation and may be followed by a second resin coating step.
