Abstract

A loop type force transmitting element is made of fiber composite or compd material. The force transmitting element has a predetermined cross-sectional shape and is open at one end. The cross-sectional area through the loop is constant along the length of the loop. However, the cross-sectional shape or configuration varies along the length of the loop. This type of structure is accomplished by machine winding the reinforcing fibers or filaments as an endless loop onto a winding core which has lateral walls spaced from each other so that the spacing corresponds to the wall thickness configuration along the length of the force transmitting element. One loop portion of the initially endless loop is severed after the composite material has been hardened whereby a loop element is formed which is open at one end.
