This is certainly attained by having a stack of numerous tiny rectangular plates in Each individual chain url that may slide independently from facet-to-side. The plates can be fairly slender, close to a millimeter thick. The conical pulleys have radial grooves. A groove on one aspect of your pulley is satisfied which has a ridge on another facet and Therefore the sliding plates are pushed forwards and backwards to conform towards the sample, effectively forming tooth of the proper pitch when site oficial squeezed in between the pulleys.
