Positively Infinitely Variable (PIV) chain drives are unique in that the chain positively interlocks With all the conical pulleys. This can be achieved by using a stack of many small rectangular plates in Each individual chain hyperlink that may slide independently from aspect-to-facet. The plates may very well be really slender, all around a millimeter thick. The conical pulleys have radial grooves.
