发明名称 PROCESS AND APPARATUS FOR MAKING PAPERMAKING BELT USING EXTRUSION
摘要 A papermaking belt (90) comprises a reinforcing element (50) and a resinous framework (300) joined together. The resinous framework (300) is formed by a plurality of resinous beads (110) which mutually contact or cross-over. Supe r- knuckles (160) extending outwardly from the reinforcing element (50) are formed at points of contact. A preferred continuous process for making the belt comprises extruding, in a pre-selected pattern, a plurality of beads (110) of a resinous material onto the forming surface thereby forming the resinous framework (300) thereon, joining the resinous framework (300) and t he reinforcing element (50) together, and then solidifying the resinous framewo rk (300). The resinous material may comprise at least two chemically-active materials capable of cross-linking upon contact.
