Abstract
A pressing roller is provided including an inner core and a roller cover structure where the roller cover structure is divided into segments. Each roller cover segment may have a rigid inner ring, an elastomeric outer ring, and a deformable coupling structure located between the inner ring and the outer ring. The deformable coupling structure may be formed from a shape memory alloy, a carbon fiber composite, or nylon.
Claims18
A pressing roller comprising:
- an inner core;
- a roller cover structure adapted to be mounted on the inner core for rotation with the inner core, the roller cover structure defining an outer surface adapted to mate with an outer surface of a mating roller to define a nip to receive one or more plies of web material, the roller cover structure comprising a plurality of roller cover segments, wherein each roller cover segment comprises:
- an inner ring positioned about the inner core;
- an outer ring spaced from the inner ring;
- and
- a deformable coupling structure located between the inner ring and the outer ring, wherein the deformable coupling structure is formed from one of a shape memory alloy (SMA), a carbon fiber composite, or nylon,
- wherein the outer ring is deformable and compressible;
- wherein the deformable coupling structure comprises a plurality of ribs coupled to the inner and outer rings;
- and
- wherein each of the ribs has a thickness that varies along its length from where the rib is coupled to the inner ring to where the rib is coupled to the outer ring.
