    • In a method and apparatus for supplying sliver cans to an automatic spinning machine and removing empty sliver cans from spinning stations of the automatic spinning machine, a can transport carriage to be driven between the automatic spinning machine and a can delivery station or empty can receiving station has can parking places for a can supply. An empty can below a spinning station is removed, placed on a free parking place, and replaced with a filled can from the can supply which is placed under the spinning station, all through the use of an automatic can changer. Two associated sliver cans are placed in succession forming two successive rows of front and rear sliver cans for supplying two adjacent spinning stations with sliver. Two free parking places are maintained for sliver cans on the can transport carriage. A rear can of a pair of cans located under a pair of spinning stations is changed by initially loading both cans of the pair onto the two free parking places with the can changer, regardless of whether or not the front can is still delivering sliver to a spinning station of the pair of spinning stations. The empty rear can of the pair of cans is then replaced with a full can. A front can of the pair of cans that may still be delivering sliver is subsequently returned to a position below the pair of spinning stations with the can changer.

    • A method and apparatus for supplying sliver to the spinning stations of a spinning machine to wind a batch of a predetermined number of packages includes a sliver can transfer device, a sliver can conveying device, a sliver can filling device and a computer for controlling the operation of the various sliver can handling devices. Each spinning station is initially provided with a sliver can having a differing amount of sliver therein than the other sliver cans as the winding of the packages of the batch is commenced. The spinning stations are then continuously individually provided with fresh cans of sliver having a uniform amount of sliver therein during the normal running of the batch. The computer executes a batch ending program to determine an individual finishing quota of packages to be wound at each spinning station and controls the sliver can conveying device, the sliver can transfer device and the sliver can filling device to deliver a final can of sliver to each spinning station for the spinning station to complete its individual finishing quota of packages. The final can of sliver provided to each spinning station contains a predetermined quantity of sliver which is selected such that the final can is substantially empty upon the winding of the last full package of the individual finishing quota of packages at the respective spinning station.
