ABSTRACT:
This invention relates to an assembly composed of a plurality of generally parallel corrugated contact sheets. The corrugations form alternating apices in the sheets. The apices are connected by angled walls. The corrugations in each sheet are substantially parallel and disposed at an oblique angle to an edge of the sheet. Adjacent sheets are oriented such that the corrugations of one sheet cross the corrugations of an adjacent sheet at intersections of the apices. The sheets have generally planar positioner pads positioned at least at some of the intersections of the apices of the corrugations of adjacent. The apices have indented portions between each positioner pad.
