Abstract

Abstract In order to render honeycomb tables with apertured table leaves clean-room compatible, sealing sheets are provided with projections corresponding in number and location to apertures in the table leaves and projecting into cells of honeycomb cores for a distance being several times smaller than the depth of such cores. These sealing sheets and their projections seal the honeycomb cells against the table leaf apertures inside the table leaves. Debris and lubricant residues accumulate inside these projections during provision of the table leaf apertures and are removed through these apertures preparatory to use of each honeycomb table in a clean room. The apertures are structured for receiving fasteners for attaching objects to the honeycomb tables. A load-bearing sealing structure may be molded from a sealing sheet or may otherwise be provided with cavities situated like the above mentioned projections. Sitting on top of the honeycomb core, that sealing structure bears the table leaf and objects or other loads placed or imposed on the table, in addition to ensuring clean-room compatibility.
