Abstract: A novel positive traction permeate tube and fittings therefor are described for use in spirally wound membrane filtration elements for filtration and separation applications. Membrane filtration elements incorporate the novel permeate tube. Methods of making the novel positive traction permeate tube are also disclosed, as are the preferred sanitary stainless steel materials used for the sanitary tube and fittings. The novel permeate tube involves a sanitary tubing having two open ends, each with an end fitting. The end fittings engage a positive traction drive for high tension spiral winding of a membrane element spirally around the novel permeate tube. Membrane filtration elements made with the novel permeate tube are less subject to slippage and breakage during manufacture and can withstand higher pressure drops and flow rates during use without failure of the spirally wound membrane element. The positive traction permeate tube facilitates membrane replacements.

Abstract: Core and spindle technology for use with ribbon materials. The invention has use in many environments in which a ribbon or sheet material is wound onto a core, for example in printers and related equipment used to produce data bearing identity documents.
