Abstract
A drive between an autoleveller output and a coiler in a carding and deposition assembly comprises slack take-up means, and means for varying the length of the sliver path. In a belt drive, the slack take-up is effected on both sides of the belt drive by dancing pulleys. These may be resiliently biassed, either by a helical tension spring, by the belt elasticity and pulley geometry, or other suitable means.
