ABSTRACT:
A process for spreading foam material relatively free of undesirable air bubbles, blisters, and blotches, and substantially uniformly in thickness across the full width of continuously advancing sheet material comprising: supplying foam material having a predetermined density to a chamber for containing foam material: filling the chamber substantially completely with the foam material at the predetermined density: maintaining the predetermined density of the foam material in the chamber substantially constant from point of entry thereto to point of exit therefrom: delivering the foam material from the chamber and spreading it relatively free of undesirable air bubbles, blisters, and blotches, and substantially uniformly in thickness across the full width of continuously advancing sheet material; and regulating and controlling the amount and the thickness of the foam material being spread on the continuously advancing sheet material, the regulating and controlling taking place immediately following the delivering of the foam material. Coating apparatus for spreading the foam material is also included.
