A platen assembly is provided for manufacturing flat-topped wave-board. The assembly can be mechanically converted between a planar configuration and a wave-like configuration to form a board with a flat-topped and bottomed profile.

A platen assembly, for use in forming flat-topped wave-board panels, comprising: first means for forming a support surface; parallel, spaced apart, elongate end members forming inner working faces that are generally perpendicular to the support surface, at least one of said end members being movable toward the other along the support surface while remaining parallel thereto; a plurality of elongate link elements positioned on the support surface in spaced relationship, between the end members, said link elements being slidable along the surface in parallel relationship, said sliding link elements forming a generally planar working surface; first and second opposed pivoting link elements, said link elements each being pivotally connected at one end to an adjacent sliding link element whereby the pair of first and second pivoting elements extend between a pair of link elements; connecting link elements forming a generally planar working surface, said connecting link elements each being pivotally connected between a pair of first and second pivoting link elements, whereby the connecting link elements maintain the pivoting link elements connected thereto in spaced apart relationship; means associated with each pair of pivoting link elements and their associated connecting link element, for releasably limiting the pivoting elements to a generally inverted v-shaped configuration, with said connecting link elements lying in a horizontal plane therebetween, when the end members are biased together; and means for moving the end members together and apart to convert the link elements between corrugated flat-topped and bottomed and planar forms.
