FIELD: cutting out flat flange gaskets and other different-contour parts, for example rectangular, round or elliptical from reinforced blanks, mainly on base of heat expanded graphite reinforced at one or both sides by means of metallic foil. ^ SUBSTANCE: unit includes electromechanical apparatus mounted in strut placed on base and device for fixing reinforced blank. Electromechanical apparatus includes electric drive, movable cutter that may perform reciprocation motion in vertical plane and that is joined with electric drive through device for moving movable cutter; two rigidly mounted stationary cutters arranged in base of unit and mutually separated by gap for passing movable cutter. Base is in the form of plate having on upper and lower sides lengthwise guiding grooves mutually communicated by means of through elongated slit. Device for fixing is placed inside slit with possibility of motion in it. Gap is normal relative to through slit. ^ EFFECT: possibility for simplifying process of making complex shape gaskets. ^ 13 cl, 7 dwg |
