Abstract

An apparatus for potting membranes. The apparatus may include a mould for receiving ends of the membranes, means for forming a first layer of a curable resin material around the ends in the mould, and means for applying a second layer of a flexible resin material to the first layer prior to full curing of the first layer. The flexible resin material may be chemically reactive with the curable resin material to form an adhesive bond therebetween. A potting sleeve may be positioned within the mould. A centrifuge may receive the curable resin and/or the flexible resin material upstream of the mould.
