Abstract
A method of making a passenger conveyor handrail includes forming a drive member having a plurality of longitudinally spaced drive surfaces. The drive member has a longitudinal stiffness for maintaining a desired spacing between the drive surfaces. The drive member is inserted into a molding device. A gripping surface portion of the handrail is formed using the molding device such that the gripping surface portion and the drive member are secured together. Another method includes forming a belt drive member having a plurality of teeth that establish a plurality of longitudinally spaced drive surfaces. The belt has a longitudinal stiffness for maintaining a desired spacing between the drive surfaces. Each of the teeth extends across an entire width of the belt. The belt is secured to a gripping surface portion of the handrail.
