Abstract
A method and apparatus in a panelboard processing line is disclosed for controlling the application of smoothing pressure to a facing sheet of a laminate comprising at least one such sheet and a layer of plastic foam. Smoothing pressure is applied to the facing sheet during continuous production of the laminate in a conventional nip-roll, free-rising foam panelboard system. To this end, provision is made for adjustably suspending a belt-like member generally parallel to, but in variably spaced relation above, the processing line at a region downstream of the conventional nip-roll in the typical free-rising foam system. The belt-like member is flexible along its longitudinal axis but is relatively stiff transversely thereof, and is so suspended as to produce a depending loop or sag intermediate its ends. Drag contact by portions of the belt member with the facing sheet of the panelboard is controlled by adjusting the suspension points of the belt to position the sag of the belt at selected locations relative to the rise profile of the developing foam as the laminate is advanced along the processing line.
