Abstract
This invention relates to a coiler using tongue and groove rollers preferably for measuring sliver thickness and guiding sliver emerging from between these rollers, using guide means such as a pair of calender rollers driven for rotation in the same conveying direction. Optionally the sliver between the conveying nip at the tongue and groove rollers and the guide means (when embodied as calender rollers) is severed by intermittent operation of the conveying and guiding nips.
