However, after extended use, the covering on the rollers wears down and must be resurfaced or replaced.
This is inconvenient and expensive as it requires that the processing equipment be shut down while the roller is being resurfaced or that the end user stock additional replacement rollers.

Embodiment Construction

The replaceable sleeve of the present invention provides several advantages over other prior sleeves that are covered with rubber or polymer in that all of the layers comprising the sleeve are seamless and may be cured in a single step, which allows the sleeve to be produced more efficiently. And, because the layers comprising the sleeve are not limited to the use of specific polymers or curing methods, the properties of the sleeve may be tailored as desired for specific applications. For example, where the sleeve is used in printing operations, the outer layer of the sleeve may be finished so that it can be used as the printing surface, thus eliminating the requirement for the attachment of separate printing plates. The sleeve of the present invention also offers the advantage that it may be easily replaced on-site without having to shut down processing equipment for extended periods of time. That is, when the sleeve surface becomes worn or otherwise needs replacement, the sleeve m...

Abstract

A replaceable sleeve having a working surface is provided which is adapted to be mounted on a carrier. The sleeve includes an inner polymeric layer, a reinforcing layer overlying the inner layer, an intermediate polymeric layer overlying the reinforcing layer, and an outer polymeric layer. The sleeve may include a cushion layer between the intermediate layer and the outer layer. The layers comprising the sleeve are formed around a support and then cured simultaneously in a single step. The resulting sleeve may be used in printing operations or in other applications such as coating, embossing, laminating, calendering and the like.

Description

BACKGROUND OF THE INVENTIONThe present invention relates to a replaceable sleeve which may be readily mounted onto a cylindrical carrier, and more particularly, to a replaceable sleeve comprising a multilayer reinforced composite which may be cured in a single vulcanizing step.Rubber-covered cylindrical rollers are widely used in industry for a number of applications, particularly for web or sheet handling and processing applications such as the embossing, calendering, laminating, printing and coating of paper, film, foil, and other materials. In addition to their use in web processing equipment, such rubber-covered rollers are often employed in conveyors and various office machines. Such rollers are typically comprised of a cylindrical (metal) core or other support with an outer covering of rubber, elastomer, or polymer material. However, after extended use, the covering on the rollers wears down and must be resurfaced or replaced. This typically requires that the rollers be sent t...
