Abstract
A process and apparatus are described for the preparation of continuous polymer foam bunstock having substantially rectangular cross-section. The novel feature comprises a panel member having its downstream end pivotally mounted above a conventional moving trough-shaped mold, the underside of said panel member floating freely in tangential contact with the rising foam in the area immediately following the gel point of said foam but before the point at which the foam is no longer sufficiently mobile to be molded without distortion of the cells thereof.
