Abstract

This invention pertains to processes and apparatus for manufacturing supported, solid, polymeric sheets from: (I) liquids containing components reactable to polymers; and (II) one or more indefinitely long, foraminous substrates. A more or less continuous sandwich is formed of such substrate(s) and, faced on each side of the substrates as a group, film extending beyond the lateral edges of the substrate(s), the plane of the sandwich deviating from vertical by not more than about 45 degrees.
