Speed frame is also called as simplex or roving frame. The speed frame process minimizes the sliver weight to a suitable size for spinning into yarn and inserting twist, which maintains the integrity of the draft strands. It is impossible to feed the sliver to ring frame for yarn production due to limitation in draft in ring frame.
