This machine is one of aid equipments in the production of metal spiral wound gasket. It can be used to shear non-metallic strips with certain width and thickness. The width parameter of the non-metallic strip is matching width parameter of the SGC-800A. The width parameter of the non-metallic strip is the basic demand of technique. The width parameter of the blade not only can be used to produce spiral wound gasket with thickness 4.5mm but also produce gasket with thickness 3.2mm and 6.5mm
