Abstract:
A method for feeding blanks in a container-forming unit to a wrapping station, wherein a blank is advanced onto a wrapping mandrel which is attached to a moving structure that transfers the wrapping mandrel between different processing stations of the container-forming unit,wherein the blanks are advanced as a continuous blank web to meet the wrapping mandrel in the wrapping station where they are detached from the end of the blank web and transferred onto the wrapping mandrel, wherein the blank web is transferred to the wrapping station from above, wherein at least one side margin of the blank web is heated in the same direction with the feeding of the blank web before the detachment point, wherein the blank web is fed by steps corresponding to the length of the blank in the direction of feed by a conveyor situated before the detachment point, and that after each feeding movement a blank is detached from the end of the blank web, wherein after a blank has been detached, it is advanced, by one straight transfer motion directed against the plane of the blank, into contact with the wrapping mandrel.
