Abstract
Handrail turn around for escalators and moving walks. In this handrail turn around, rolling element bearings, press fitted on axle bolts can be assembled more economically in that lateral flanges of the reversing band are stamped so as to form nearly semicircular cutouts into which the axle bolts, with their press fitted rolling element bearings, can be snapped, with the cutouts having a narrow portion that is narrower than the diameter of the associated axle bolts, with a central flange on the axle bolt serving as an abutment for the rolling element bearings wherein each two of the opposed bent flanges are preloaded so that the axle bolts can readily be clamped, whereinafter after the insertion of the axle bolts, the reversing band is bent into its operative shape, with the handrail guide section also serving as a cover for the handrail turn around.
