Process and apparatus for the continuous production of single-ply or
multi-ply webs of heat-curable resin
摘要:
Process for the continuous production of single-ply or multi-ply laminates, comprising feeding from below and at an obtuse angle, a web uniformly coated with resin, on to a fiber web or reinforcing web which is under tension, so that the resin penetrates the fiber web or reinforcing web in a bubble-free manner, and then passing the fiber web or reinforcing web uniformly impregnated with resin, either by itself or conjointly with one or more separating films or decorative films or resin-impermeable covering films, through a heating zone and pressure zone, whereby a single-ply or multi-ply laminate is produced. Apparatus for carrying out the process is also described.
