ABSTRACT:
A drafting system and autoleveller are arranged such that the "tongue" roller and the "grooved" roller of the sliver sensor ahead of the first drafting rollers serve to measure the thickness of the sliver therebetween, and their output signal is used, subject to a time delay, to vary the draft ratio in the subsequent drafting means. The autoleveller throughput speed is adjustable and the time delay in the draft ratio variation is automatically adjusted in response to the speed selected.
