DRIJFBAND MET DOOR STEUNELEMENTEN GEVORMD TRAPEZIUM- PROFIEL.

摘要

The trapezoidal cross-section or profile of an endless driving belt is shaped by means of an uninterrupted row of thin metal plates transversely mounted on a metallic pull band over the entire length thereof. The plates are pressed against each other by tensile stress in the pull band. The pull band may advantageously be subdivided into two separate, parallel band strips each these two strips being inserted from oppisite sides in sideward slots provided in the metal plates. The alignment of each plate in a plane perpendicular to the longitudinal direction of the band is maintained by coupling means between all contiguous plates preventing lateral shifting of each plate with respect to its adjoining plates but allowing a slight mutual tipping of the plates around an axis perpendicular to the longitudinal direction of the pull band and parallel to the plane thereof.
