Methods of cutting patted hollow filaments
First Claim
1. A method for removing thin layers from solid potting masses containing hollow filaments for fluid separations to expose the bores of the hollow filaments comprising moving a knife blade edge in an essentially arcuate path to impact the potting mass with the knife blade edge at a sufficient velocity to cause localized fracturing of the potting mass at the point of impact thereby removing the thin layer of the potting mass.

Abstract
Hollow filaments, which are suitable for use in separating one or more components from a fluid mixture by selective permeation, are embedded, or potted, in a solid potting mass and the potting mass is severed to expose fluid communication openings of the hollow filaments. In accordance with the invention a thin layer of the solid potting mass having the hollow filaments embedded therein is removed by planing or milling using a knife blade edge moving in an essentially arcuate path at sufficient velocity to cause fracturing of at least one of the hollow filaments and solid potting mass at the point of contact with the knife edge.
