METHOD AND APPARATUS FOR CUTTING EXPANDED GRAPHITE SHEET MATERIAL

摘要

-26- A method and apparatus for cutting an expanded graphite sheet comprises (a) urging at least one cutting tool against the sheet, the cutting tool having at least one ridge extending therefrom, the ridge comprising a substantially tapered cross-section having sloping sides and an edge surface; (b) displacing at least a portion of the material comprising the sheet as the ridge is urged against the sheet; and (c) compressing a region of the sheet in contact with the at least one ridge so that the density of the region at least reaches the breaking density of the sheet.
