Abstract
A transmission belt for driving and/or supporting an elevator car has a longitudinally extending body including an area tensile layer reinforced by chemical fibers. The belt can have a flat friction layer or a friction layer including alternating longitudinally extending wedge-shaped ribs and grooves. Transverse grooves can be formed across the width of the longitudinally grooved friction layer.
