ABSTRACT:
The invention relates to a method and an apparatus for cutting off and guiding a strip cut from the edge of a paper web in a threading operation. The strip is released from a cylinder by blowing and is guided by pocket blowing so as to form a bag and is then cut off. The strip is conducted through an arrangement functioning as a draw-press, which pulls the strip against a cutting member of a cutting device in such a way that it is severed and the strip can immediately be transferred further.
