Abstract
A papermaking belt comprises a reinforcing element and a resinous framework joined together. The resinous framework is formed by a plurality of resinous beads which mutually contact 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 contact.
Claims20
A papermaking belt comprising a reinforcing element and a patterned resinous framework joined to the reinforcing element and extending outwardly therefrom, the resinous framework further having a plurality of deflection conduits therein, the resinous framework comprising:
- at least a first plurality of resinous beads and a second plurality of resinous beads, the at least first and second pluralities of resinous beads being joined to the reinforcing element, the first plurality of resinous beads having a first thickness, and the second plurality of resinous beads having a second thickness, wherein
- the at least first and second pluralities of the resinous beads at least partially overlap at points of contact, thereby forming super-knuckles therein, the deflection conduits being disposed intermediate the points of contact, the super-knuckles having a third thickness greater than either one of the first thickness and the second thickness.
A papermaking belt comprising:
- a reinforcing element;
- and
- a patterned resinous framework having a plurality of deflection conduits therein, the resinous framework comprising at least one plurality of resinous beads interconnected in a pre-selected pattern, the resinous framework further having first portions and second portions, wherein only the first portions of the resinous beads are directly connected to the reinforcing element such that the resinous framework is securely joined to the reinforcing element and partially movable relative thereto.
A papermaking belt comprising a reinforcing element and a patterned resinous framework joined to the reinforcing element and extending outwardly therefrom, the papermaking belt made by a process comprising the steps of:
- (a) providing a forming surface having a longitudinal direction and a transverse direction;
- (b) providing at least a first extrudable resinous material;
- (c) providing at least one first extrusion die structured to extrude the first resinous material onto the forming surface;
- (d) supplying the at least first resinous material into the at least one first extrusion die and extruding the at least first resinous material from the at least first extrusion die onto the forming surface in a pre-selected pattern such as to form at least one plurality of resinous beads interconnected in a pre-selected pattern and having first portions and second portions;
- (e) causing the resinous framework and the reinforcing element to join together such that only the first portions of the resinous beads are directly connected to the reinforcing element;
- and
- (f) solidifying the resinous material, whereby the resinous framework is securely joined to the reinforcing element and partially movable relative thereto.
