Problems solved by technology

In this way, the underlying layer hardens quickly, but the final thickness of the overall coating or layer is greater
However, this approach causes a significant increase in casting time

Embodiment Construction

[0021] Hereinafter, the present invention will be described in more detail, wherein preferred embodiments of the invention are represented. This invention may however be embodied in various ways and should not be considered limited to the embodiments set forth herein. Rather, these embodiments are provided so that the description herein will fully and fully convey the scope of the invention to those skilled in the art. In the drawings, the same reference numerals denote similar elements, and the thickness and size of some components or structures may be exaggerated for clarity.

[0022] Referring now to the drawings, a casting system generally designated 19 is shown in image 3 and 4 middle. Casting system 19 includes a core 20 and a multi-outlet nozzle 22 . Consists of the mandrel itself (the mandrel is usually made of metal and optionally has its surface treated with adhesive or other material) or in combination with one or more overlapping layers of polymeric material o...

Abstract

A method for forming coverings for industrial rolls comprising the steps of: providing an elongated cylindrical core (20) having a longitudinal axis (A1); rotating the core (20) about the longitudinal axis (A1); providing With respect to a nozzle (22) moving within a nozzle path (N) substantially parallel to and above the longitudinal axis of the core, the nozzle (22) has at least an upstream outlet (24) and a downstream outlet (26), the nozzles being longitudinally offset from each other by one distance (d); and as the nozzle moves along the nozzle path, multiple strips of polymeric material are applied to the core via the nozzle outlet such that the downstream strips (28) form overlapping helical inner layers, and the upstream strips (36) An overlapping helical outer layer is formed covering the inner layer, the inner and outer layers being bonded to the core (20).

Description

technical field [0001] The present invention relates generally to a covering for an industrial roll, and more particularly to a method of forming a covering for an industrial roll. Background technique [0002] In a typical paper machine, an aqueous slurry or suspension of cellulose fibers (known as paper stock) is supplied to the upper part of an endless belt made of braided wire and / or synthetic material running over two or more rolls top of the itinerary. The upper surface of the belt, commonly referred to as "forming fiber", provides a papermaking surface on its upper run to separate the cellulosic fibers of the papermaking stock from the aqueous medium, thereby forming the wet paper web. The aqueous medium is drained from the mesh openings of the forming fibers, known as discharge holes, by gravity or vacuum on the lower surface of the fiber's upper run (ie, the "machine side"). [0003] After leaving the forming section, the web is conveyed to the press section of th...
