Estimating the term…
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.
An endless driving belt with a trapezoidal cross section which is shaped by a series of metal plates in close contact with one another transversely mounted on a metallic pull band as an uninterrupted row over the entire length thereof, each of said transverse members having a cross section which tapers inwards from the endless metallic band, said metal plates being provided in an uninterrupted row along the whole length of said pull band, the total thickness of all of said transverse metal plates as measured in the plane of the said pull band exceeding the length of said pull band in its original unstressed condition to such an extent as to obtain an intensity of tensile stress in said endless band wherein, in any operative position thereof, said transverse plates are pressed against each other.
