Abstract

Spongeous nylon matrix ribbon as described in U. S. Patent 3,413,184 is formed into an endless seamless loop by dip casting. Layers are built on cylindrical form 10 first from nylon matrix solution 11 and second from nylon backing solution 12. The layers arc dried between dippings by rotating form 10 in a warm air draft. The cast cylinder 13 is then peeled and slit into bands 14 of desired width. For larger bands, cylindrical form 10 is made of an inflatable release material such as silicone rubber or polytetrafluorethylene.
