ABSTRACT:
An autoleveller derives the signal for its draft correction from an averaged value of the sliver weight or thickness signals in each of a plurality of unit lengths of the sliver path. A preferred embodiment uses upstream and downstream sliver weight or thickness measuring means to derive signals for a draft correction and the gain of a draft correction made in response to the first sliver measuring means is varied in response to the averaged signal from the second sliver measuring means.
