Summary:The invention relates to a method for controlling a carding machine (100) and to a carding machine (100), comprising: at least one feed roller (1) and a doffer (5) which each have separate controllable drives, wherein the carding machine (100) is designed to produce a sliver, which can be deposited in cans (15), from fibre flocks or a cotton stock, wherein, to exchange cans, the circumferential speed of the feed roller (1) is changed and the circumferential speed of the doffer (5) is subsequently changed with a time delay (Δts; Δte); a sensor (S2) which is designed to measure the mass of the sliver produced or the change in mass of the sliver produced, wherein, during each can exchange, a controller (20) of the carding machine determines the standard deviation (Ss2) of the change in mass (Δm) of the sliver based on the signal from the sensor (S2) and assigns a mean value (Ms2) to this standard deviation, wherein the controller (20) is designed to optimise the time delay (Δts; Δte) by means of at least two mean values (Ms2).
