Abstract
A dialyzer is formed by first placing a film strip into a membrane hose and then simultaneously folding the hose and a netting intermediate layer so that the folds of the hose and the folds of the netting extend crosswise relative to each other in a mutually interlocking manner. The facing ends of the hose layers are then sealed with a curable sealing compound and severed. Then the film strips are withdrawn from the hoses in the so formed package. The resulting product is a dialyzer or hemofilter, depending on the type of membrane hose used, in which the facing ends of the membrane hoses are open for the passage of blood therethrough, after the withdrawal of the film, and in which the netting layers are located between adjacent hoses.
