发明名称 METHOD FOR PRODUCING SEALING ELEMENTS
摘要 A method for producing annular metallic sealing elements by bringing at least two sheet metal strips or foil strips having predefinable thicknesses, lengths, and widths into operative connection with each other in the manner of a tailored blank or patchwork, subsequently winding this composite to obtain a tube, wherein the mutually facing end regions of the tubular multilayer composite are connected to each other non-positively or positively or by bonding, or combinations thereof, notably by thermal action such as by welding or soldering, and either dividing the tube into individual ring elements, which are subsequently formed using mechanical shape-forming to obtain the respective sealing element, or forming the entire tube and dividing the tube thus profiled into ring elements to obtain individual sealing elements.
