Capabilities

EDLON’s Roll Covers have been used in paper mills around the world since 1964. They are also used in Converting, Textile mills and Food Processing. Hundreds of machines use our Roll Covers in a variety of grades and applications.

Paper Rolls in the Wet Press Sections; Blow Roll, Fly Roll, Pick-Up Roll. Rolls in the Press Sections often have fiber build up which can mark or damage the sheet. An EDLON Roll Cover will reduce or eliminate build-up and the time involved in cleaning these rolls. The Roll Cover can be applied over steel, aluminum, fiberglass, composite, or rubber covered rolls.

EDLON’s proprietary seaming equipment produces a nearly undetectable weld of the sleeve. The seam weld strength is equal to the virgin material.

EDLON covers can be provided for metal, rubber, or Fiberglass rolls - straight, crowned, bowed, groove, or wormed rolls.
