The plates might be pretty thin, all around a millimeter thick. The conical pulleys have radial grooves. A groove on a single facet with the pulley is met having a ridge on one other aspect and so the sliding plates are pushed backwards and forwards to conform towards the pattern, efficiently forming tooth of the right pitch when squeezed amongst the pulleys.
