Abstract
The method for operating a fleece layer requires a fleece layer, to which the card web is supplied at variable card web infeed speed. To limit the amount of space required for the upper carriage at the rear of the machine, the average of the absolute values of the laying-carriage speed during the forward movement of the laying carriage in at least some laying cycles differs from the average of the absolute values of the laying-carriage speed during the return movement of the laying carriage, and the average of the absolute values of the laying-carriage speed in at least some laying cycles during the forward movement of the laying carriage differs from twice the average of the absolute values of the upper-carriage speed during the forward movement of the laying carriage.
