Abstract
Abstract An improved apparatus for assembling a convolute wound structure suitable for use in making an element of a selective permeation separation device comprises 1. A WEB FEEDER ADAPTED TO UNROLL A WEB-LIKE FORAMINOUS MATERIAL IN SUBSTANTIALLY PLANAR FORM, 2. A TAKEUP ADAPTED TO WRAP THE WEB-LIKE MATERIAL AROUND A CORE TO FORM A CONVOLUTE WOUND STRUCTURE, 3. A WHEEL STRUCTURE BEARING PACKAGES OF HOLLOW FILAMENT PERMEATION SEPARATION MEMBRANES AND ADAPTED TO WRAP THE HOLLOW FILAMENT MEMBRANES AROUND THE PLANAR WEB-LIKE MATERIAL AS THE WHEEL ROTATES AND THE WEB-LIKE MATERIAL IS UNROLLED BY THE WEBFEEDER AND WRAPPED AROUND THE CORE BY THE TAKEUP, 4. GUIDES ADAPTED TO SUPPORT THE TWO EDGES OF THE WEB-LIKE MATERIAL WITH EACH EDGE WRAPPED NOT LESS THAN ABOUT 180* AROUND A GUIDE, AND 5. GUIDES FOR THE FILAMENTS ADAPTED TO CAM THE FILAMENTS TO PREDETERMINED POSITIONS ON THE WEB-LIKE MATERIAL.
