Abstract

The invention relates to a cutting device for a web winder.
The cutting device includes a frame construction and a cutting blade, by means of which cutting blade the web in a reel formed on support of carrier drums can be cut off before new winding is started. The cutting device preferably includes an actuator and power transfer members which are operationally connected with the cutting blade of the cutting device. In this manner, the movement of the actuator is transferred by an intermediate of the power transfer members to the cutting blade so that the cutting blade moves along a curved path. The cutting blade is thereby movable between a lower position and an upper position, the cutting blade in its lower position being substantially more distant from the carrier drum than in its upper position.
