摘要: Methods and apparatus for continuously forming thin-gauge flexible foam sheeting by controlling the rise of an expanding foam-forming mixture (3) until reaction is substantially complete. The cast onto a conveyed first facing material (31), after which second (32) applied to mixture, sandwich. Dispersing means (33) squeeze sandwich evenly distribute between sheets. Rise controlled maintaining gap multiplicity pairs upper rollers (42) lower (43).
