Process and apparatus for making papermaking belt using extrusion

本发明公开了一种造纸带(90)，其包括加强元件(50)和结合在一起的树脂框架(300)。树脂框架(300)通过多个相互接触或交叠的树脂小珠(110)形成。从加强元件(50)向外延伸的上关节(160)在接触点上形成。制造造纸带的优选连续方法包括以预选图案将多个树脂材料的小珠(110)挤到成形表面上，从而在其上形成树脂框架(300)，将树脂框架(300)和加强元件(50)结合在一起，然后凝固树脂框架(300)。树脂材料可以包括至少两种化学活性的材料，它们能在接触时交联。 A parpermaking belt comprises a reinforcing element and a resinous framework joined together. The resinous framework is formed by a plurality of resinous beads which mutually contract or cross-over. Super-knuckles extending outwardly from the reinforcing element 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 of a resinous material onto the forming surface thereby forming the resinous framework thereon, joining the resinous framework and the reinforcing element together, and then solidifying the resinous framework. The resinous material may comprise at least two chemically-active materials capable of cross-linking upon contract.
