Abstract

A honeycomb seal and a method of its manufacture, especially for use in sealing between rotating and non-rotating components of turbomachinery. The honeycomb seal has a plurality of open cells and is manufactured from a single strip of material. The strip is repeatedly folded back onto itself so as to form layers wherein each layer abuts at least one neighbouring layer of the strip of material. Each of the layers of the strip has at least one trough corrugation and at least one peak corrugation which define opposing sides of the open cells. Each trough corrugation of each layer abuts a peak corrugation of a neighbouring layer so that the opposing sides define the complete the open cells which may be hexagonal, rectangular or sinusoidal edged shape.
