Abstract

See full text

Two lap slivers lying one on top of the other are continuously fed to the combing tools in a plurality of combing heads of a combing machine. The first lap sliver comes from a first lap roll carried by a rear carrier device, and runs over a front carrier device. A second lap roll is carried on this, from which the second lap sliver emanates. A detector determines when the end of the lap sliver from the first lap roll is running out in one of the combing heads. A control unit then executes a lap roll change on several combing heads simultaneously as follows: The end of the first lap sliver is severed to the same length in all the combing heads. The cut-off pieces of the lap slivers and the winding tubes of the first lap rolls are removed. The second lap rolls are rolled on to the rear carrier devices. New lap rolls are so placed on the front carrier devices that the start of the lap sliver on these new rolls is aligned with the end of the first lap sliver. In this way, the lap roll change can be executed completely automatically and without stopping the machine.
