For the purpose of transferring a leader of a web-formed material ( 1 ) from a first treatment step to a subsequent second treatment step, the web-formed material ( 1 ) is divided by forming a strip ( 1 a) in one edge portion of the web-formed material. The strip ( 1 a) is passed in between two sharp edges ( 5 a, 6 a) located close to each other, such that the two sharp edges ( 5 a, 6 a) embrace the strip like a pair of shears. Thereafter, one of the sharp edges ( 6 a) is moved towards the other ( 5 a) so that said one edge ( 6 a) passes said other edge ( 5 a), hence cutting off the strip. With the same movement, the leader is given an impulse, in a direction essentially perpendicular to the strip ( 1 a), towards a leader conveyor ( 7,8 ) which intercepts the leader and passes it into the second treatment step. |
