  • Patent number: 5031850
    Abstract: A rewinder for converting large supply rolls of paper into smaller rolls such as toilet tissue and kitchen towels includes a pair of winding cylinders, the surfaces of which are spaced slightly apart to create a nip therebetween. The cylinders rotate in the same direction, so as to create opposing surface movement in the area of the nip. A web of paper enters the nip and crosses therethrough from one winding cylinder to the other, passing firstly the winding cylinder, the surface of which is moving in a direction opposite to the incoming direction of the web. A core on which the web is to be wound is to be inserted into the nip, pinching web between the first winding roll, causing a reverse movement in the direction of the web and separating the web in the nip between the two winding cylinders.
