Process 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.

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.
