  • Elevator belt splice
    Patent number: 4056867
    Abstract: A splicer element for a belt includes juxtaposed splice or clamp elements with a spacer element disposed between the clamp elements. The ends of the belt are disposed between the clamp elements and the spacer element. The surfaces of the clamp elements and the spacer element that contact the belt surfaces are rough, whereby the frictional holding properties of the belt splicer element are greatly increased. One form of surface roughness is a plurality of projections that dig into and may pierce the belt material.
