High pressure water jet comminuting

摘要

Broke handling and reducing apparatus and method for comminuting a moving continuous sheet or web material such as paper broke in the dryer or converter section of a papermaking machine, includes a plurality of high pressure water jet cutting nozzles mounted in spaced-apart relation transversely to the direction of movement of the material and are mounted so as to direct high pressure cutting jets into the path of movement. The nozzles are mounted so that at least some of the nozzles are cyclically moved with respect to others of said nozzles to form a plurality of mutually intersecting jet cutter paths to reduce the material into a multiplicity of smaller discrete or easily separable pieces.
