Patent number: 10260661Abstract: The invention relates to line elements (600) consisting of a multi-layer inner element (IE) and an outer element (AE), wherein the inner element (IE) and the outer element (AE) are in contact with each other at points, at lines, over part of the surfaces thereof, or over the full surfaces thereof. Furthermore, a frictional contact protection means extending over the component length is provided, or a frictional layer (121) is provided in the contact region of the inner element (IE) and the outer element (AE). The wear of the outer element (AE) caused by friction can thereby be minimized.Type: GrantFiled: June 8, 2016Date of Patent: April 16, 2019Assignee: WESTFALIA METALLSCHLAUCHTECHNIK GMBH & CO.
