Abstract

The honeycombed construction consists of several strips forming cells. The strip sections(12) which form adjoining surfaces of the finished cells, have contacting surfaces (13). There are also non-contacting sections (14), which define an intermediate space. All strips are fastened to a common carrier sheet(15). The contacting surfaces are formed by pressing, and are located on the edge of each strip opposite to the sheet. The strips consist of metal sheets, welded to each other, and then soldered or adhered to the carrier sheet. The space between the strips is of sufficient size, to prevent a flow of solder or adhesive between adjoining surfaces by capillary action.
