Process for dispersing a fibrous paper stock and device for performing the process

Abstract

Process and apparatus for dispersing fibrous paper stock that includes delivering an aqueous fibrous paper stock, pressing some water out of the aqueous fibrous paper stock to form a highly consistent coarse fibrous paper stock, and introducing the highly consistent coarse fibrous stock into an effective area of a mallet roll having circulating mallets which cooperate with fixed peripheral impact sections. In this manner, the highly consistent coarse fibrous stock is loosened and distributed. The process also includes transporting the highly consistent fibrous paper stock into a dispersing machine, and dispersing the highly consistent fibrous paper stock in a dispersing machine.

Description

[0001] The present application claims priority under 35 U.S.C. .sctn. 119 of German Patent Application No. 100 18 262.3, filed on Apr. 13, 2000, the disclosure of which is expressly incorporated by reference herein in its entirety.[0002] 1. Field of the Invention[0003] The invention relates to a process and device for dispersing fibrous paper stock. The preocess includes providing an aqueous fibrous paper stock, pressing out some of the water to form a highly consistent coarse fibrous paper stock, transporting the highly consistent coarse fibrous paper stock into a dispersing machine, and dispersing with a dispersing machine. The dispersing machine includes at least two dispersing fittings (tools, elements), which have several interlocking lines of teeth and are movable relative to one another at a distance so as to disperse the highly consistent fibrous paper stock.[0004] 2. Discussion of Background Information[0005] Processes of the above-mentioned type are used, for instance, for...
