Abstract
A belt end connection and method for fastening a belt end in an elevator installation includes a housing having a wedge pocket for holding the support belt end and a wedge. At least one wedge pocket surface facing the wedge is provided with a roughness that is different from a roughness of another surface of the wedge pocket. Advantageously, a wedge pocket adhesion surface lying closer to a loose run of the support belt is provided with a roughness greater than the roughness of the another surface, or a wedge pocket slide surface lying closer to a supporting run of the support belt is provided with a roughness less than the roughness of the another surface.
