Abstract
A roll and a process of making a roll for smoothing a web. The roll includes a roll core having an outer surface. A covering layer disposed on the outer surface of the roll core, the covering layer having an inner surface and an outer surface. The covering layer includes a resilient matrix material and fibers. The number of fibers varies radially from the inner surface to the outer surface of the covering layer. The process includes providing a roll core having an outer surface, and applying a covering layer on the outer surface of the roll core the covering layer having an inner surface and an outer surface. The covering layer includes a resilient matrix material and fibers, wherein the number of fibers varies radially from the inner surface to the outer surface of the covering layer.

A roll for smoothing a web comprising:
- a roll core having an outer surface;
- and
- a covering layer disposed on the outer surface of the roll core, the covering layer having an inner surface and an outer surface;
- the covering layer comprising a resilient matrix material and fibers,
- wherein the number of fibers varies radially from the inner surface to the outer surface of the covering layer, and
- wherein the number of fibers near the inside surface is greater than the number of fibers near the outside surface.
A process for making a roll for smoothing a web comprising:
- providing a roll core having an outer surface;
- and
- applying a covering layer on the outer surface of the roll core, the covering layer having an inner surface and an outer surface, the covering layer comprising a resilient matrix material and fibers,
- wherein the number of fibers varies radially from the inner surface to the outer surface of the covering layer, and
- wherein the number of fibers near the inside surface is greater than the number of fibers near the outside surface.
A roll for smoothing a web comprising:
- a hard metal roll core having an outer surface;
- and
- a resilient covering layer having an inner surface region, a middle region, and an outer surface region, the inner surface region being affixed to the outer surface of the hard metal roil core;
- the resilient covering layer comprising a resilient resin matrix material and a plurality of one of glass fibers and carbon fibers embedded in the matrix material,
- wherein the outer surface region of the resilient covering layer comprises substantially no fibers, the middle region comprises some fibers, and the inner surface region comprises more fibers than the middle region.
