The elevator belt for elevator unit, comprises wedge rib arrangement (15) having two wedge ribs (15.1) extending in longitudinal direction of the belt, which forms a contact side to the interference with a driving wheel for elevator unit, a traction support arrangement having two traction supports (14.1, 14.2) in which two ribs of the wedge rib arrangement are arranged adjacent to each other, and a back layer (13) in which one of the contact side is formed oppositely to the back side of the elevator belt. The elevator belt for elevator unit, comprises wedge rib arrangement (15) having two wedge ribs (15.1) extending in longitudinal direction of the belt, which forms a contact side to the interference with a driving wheel for elevator unit, a traction support arrangement having two traction supports (14.1, 14.2) in which two ribs of the wedge rib arrangement are arranged adjacent to each other, and a back layer (13) in which one of the contact side is formed oppositely to the back side of the elevator belt. The back layer forms a flat profile with a bar (13.1) projecting to the contact side into the wedge rib arrangement. The traction support of the traction support arrangement comprises stranded wire or ropes of single- or multiple twisted wires and/or plastic yarns cover. The wedge ribs of the wedge rib arrangement have a coating on the contact side. An intermediate layer is arranged between the wedge rib arrangement and the back layer. The bar is arranged at or near the deepest place of two wedge ribs connecting wedge rib groove. Two adjacent wedge ribs of the wedge rib arrangement are connected with one another in single piece manner and are separated from each other by a continuous groove, into which a bar of the back layer protrudes. Independent claims are included for: (1) a method for the production of elevator belt; and (2) an elevator unit. |
