A center cord-line V-belt with a radially centered cord line of helically wound tensile cord embedded in a very high-modulus adhesion gum, an overcord layer, and an undercord layer. The adhesion gum has a substantially isotropic modulus, while the overcord and undercord layers have anisotropy in with-grain and cross-grain moduli. The overcord and undercord cross-grain moduli are less than the adhesion gum modulus. The anisotropic moduli are the result of oriented short fibers and the with-grain modulus is oriented axially in the belt. The adhesion gum preferably has no short fiber. The belt preferably has no reinforcing fabric layer and no fabric wrap. The adhesion gum, overcord layer and undercord layer are preferably based on an ethylene-alpha-olefin elastomer, with peroxide cure, reinforcing filler, and metal salt of an α-β-unsaturated organic acid. The belt may have notches on one or both of the inner and outer radial surfaces for additional flexibility.

Center cord-line V-belt

A banded frictional power transmission belt with a satin-weave, band fabric wrapped around the outside of the belt. The band fabric may be a satin weave of warp and weft yarns and may include a high-strength, wear-resistant yarn such as aramid fibers, and may include a high-adhesive yarn such as nylon and/or cotton. The aramid and/or nylon fibers may be staple or filament fibers. The band fabric may be treated. The band fabric may have a 4&#xd7;1 satin weave. The band fabric may be wrapped on a bias. The high-adhesive yarn may predominantly reside on the inside of the fabric contacting said V-belt, and the high-strength, wear-resistant yarn may predominantly reside on the outside of the fabric which is the outer, pulley-contacting surface of the belt. The banded belt may be a V-belt, round belt, dual-V-belt, or multiple V-belts, or have another friction belt profile.

Banded friction power transmission belt

A single strand banded V-belt is described featuring at least one ply of a band fabric which traverses the bottom surface and each of the side surfaces of the belt body so as to cover the load-carrying section at the position that it intercepts the side surfaces of the belt body. The ply of band fabric does not overlap with itself. The total sum of the number of plies of band fabric positioned on both side surfaces of the belt body exceed the total sum of the number of plies of band fabric positioned on the top plus bottom surfaces of the belt body.
