Positively Infinitely Variable (PIV) chain drives are distinct in that the chain positively interlocks with the conical pulleys. This really is achieved by aquiring a stack of many tiny rectangular plates in Every single chain hyperlink that will slide independently from facet-to-facet. The plates might be really skinny, all-around a millimeter thick. The conical pulleys have radial grooves.

[three] The V-belt should be pretty rigid in the pulley's axial path to produce only limited radial actions even though sliding out and in with the pulleys.
