    摘要： A device for rolling up a paper web (P) in a roll forming space (30) and ejecting the formed roll. During the rolling up process, the roll forming space (30) is bounded at three contact points which are spaced apart in the peripheral direction of the roll, the roll forming space (30) having a centre (M1) and the connecting lines between the said contact points forming a triangle inside which the centre (M1) of the roll forming space (30) is situated. Two of the contact points, which are formed by driven rollers (4, 5), are disposed at fixed points in the frame and a third contact point is disposed to be displaceable in order to follow the increase in the diameter of the roll during its formation.
    The roll forming space (30) is provided with guide means (13) which guide the paper web (P) along a curved roll-up path during a first revolution. The guide means (13) and the third contact point are displaceable between a position in which they define the roll forming space (30) and a position in which they leave an ejection opening free for a roll formed in the roll forming space (30).
