AN APPARATUS FOR PRODUCING FOAM SECTIONS FROM COMPONENTS THAT REACT QUICKLY WITH ONE ANOTHER WHEN MIXED

摘要

In the production of foamed articles wherein the foam producing reaction occurs between the belts of a double belt conveyor and the double belt conveyor serves as a mold, the pressure of the foaming reaction of the belts is sensed and, to obtain a uniform structure in the product, the feed rate of the components reacting to from the foam, per unit area of the belt, is correspondingly varied.
