Abstract

The present disclosure relates to a wound roll of connecting elements, the wound roll comprising a continuous metal strip comprising (i) a support structure, (ii) a plurality of connecting elements, and (iii) a plurality of extensions being directed out of the plane of the metal strip; wherein each connecting element is associated with at least one holding arm integrally linking the connecting element to at least one of (a) the support structure and (b) one or more other connecting elements, and wherein the wound roll comprises a plurality of individual windings of the metal strip, and wherein each individual winding is adjacent to and kept at a distance from an adjacent individual winding by the extensions of the metal strip, and wherein each connecting element comprises a metal substrate having a first joining surface on one side of the substrate and a second joining surface on an opposite side of the substrate, wherein each joining surface comprises hard particles fixed on the metal substrate by a binder layer. The present disclosure further relates to a process for producing said wound roll and to a process for producing a plurality of individual connecting elements, and to the use of a connecting element made from said wound roll to connect a first component and a second component to be joined in machine, plant or motor vehicle construction, in energy generation, or in microelectronic or micromechanic equipment.
