Abstract: In the method for feeding blanks in the container-forming unit, the blank is advanced onto the wrapping mandrel which is attached to a moving structure, which moves the wrapping mandrel between the different processing stations of the container-forming unit. Blanks are advanced as a continuous blank web to the wrapping mandrel of the wrapping station, where they are detached from the end of the blank web and advanced onto the wrapping mandrel. The blank web is fed by means of a conveyor situated before the detachment point in the feeding direction by steps corresponding to the length of a blank, and after each feeding movement a blank is detached from the end of the blank web.
