A continuous variable transmission belt includes a set of nested metal rings, the set interacting with transverse elements provided slidably along the set, and the rings of the set being accommodated with small mutual play between each pair of adjacent rings, where for at least the majority of the pairs of adjacent rings the nominal value of the play is zero. The innermost and outermost rings having an elasticity modulus significantly lower than the intermediate rings.

Belt for a continuous variable transmission, comprises an endless carrier for taking up tensile forces, and a plurality of transverse elements moveable in the longitudinal direction along the carrier. The elements are provided with at least one saddle surface for contacting the carrier. The saddle surface defines an ultimate mutual position of the carrier and the elements relative to each other within the belt in radial direction, with a tapered lower part including a rocking edge and an upper p...

A process of manufacturing a belt wherein a plurality of strips of a first material are sewn together to create an outer member having a desired length with a plurality of vertical seams. A layer of a second material is placed over the seams and sewn thereto create a plurality of vertical slots. After staves are inserted in the slots, a layer of a resilient material is placed over the second material and a layer of perforated material is placed over the resilient material. A strip of material is...

In a V-ribbed belt used in a manner of bringing the back face as well as the bottom face into contact with pulleys, a hiding layer for hiding the texture of the belt is formed on a part of the side faces of the belt body, and a mark indicating the history of belt manufacturing is provided on the hiding layer. This prevents the occurrence of inconveniences resulting from the formation of the mark on the belt back face and keeps the mark recognizable for a long time.

Belts (10) are known which have a main body (11) having a smooth circumferential surface (12) on which a profiling is arranged. According to the invention the profiling is formed by an envelope body (13) surrounding the circumferential surface (12) of the main body (11). The belt (10) can thus transmit heavy driving and conveying forces. The belt (10) is therefore particularly suitable as a driving or conveyor belt.

Herein described is a belt including a unitary buckle which is used to connect the ends of the belt together around the user's waist. The buckle includes a relatively flat member having a pair of openings therein which forms a center cross member between the openings. One end of the belt is coupled to the cross member. An inwardly extending tab protrudes from one side of the flat member towards the cross member. The other end of the belt has a plurality of locking apertures which are formed to m...

A power transmission drive belt having a plurality of equally spaced teeth of identical contour disposed along its length. The teeth include a crest with driving and trailing faces depending therefrom to a valley below. An apex is disposed on each tooth and in each valley to provide minimum engagement between the belt and a pulley, resulting in a quiet running power transmission drive system.
