[figure] [caption] The pick-up or delivery rolls I, I', I[supscrpt]2[end supscrpt] are driven alternately fast and slow relatively speaking, due to the shifting of the friction ring E by the action of cam groove M' on bell-crank-lever N and consequently the rolls I, I', I[supscrpt]2[end supscrpt] pick up or deliver the braid either relatively fast or slow and, as previously set forth, alternate lengths are woven closely and loosely.
