Turn-up Device For a Reel-up Forming a Single Reject Part

A turn-up device for a reel-up for reeling of fiber webs comprising:

• a fiber web mounted for motion in a machine direction, the fiber web having a first edge and a second edge and therebetween a cross-machine width, the width having an imaginary center line which extends in the machine direction;
• a first water jet nozzle mounted for cross-machine movement to a first guide which allows travel of the first water jet nozzle from the first edge of the fiber web over the imaginary center line by 0.3 to 1 meters but not to the second edge;
• wherein a first source of cutting pressure is provided to the first water jet nozzle to form a first water jet;
• a second water jet nozzle mounted for cross-machine movement to a second guide which allows travel of the first water jet nozzle from the second edge of the fiber web over the imaginary center line by 0.3 to 1 meters but not to the first edge;
• wherein a second source of cutting pressure is provided to the second water jet nozzle to form a second water jet;
• an adhesive applicator mounted over the imaginary center line for applying adhesive on a tail end to attach the tail end onto a finished parent roll and on a beginning end to attach the beginning end onto a reeling shaft;
• a turn-up control means controlling the turn-up and reeling of the reel up and further functionally connected to a control and actuating means controlling the application of adhesive with the adhesive applicator;
• and
• wherein the turn-up control means is functionally connected to a control and actuation means which controls the movement, starting and stopping of waterflow to cause a first and second cutting of the first water jet and the second water jet so as to form the tail end into a convex shape and the beginning end into a convex shape with a single reject part therebetween which is detached so as to be drawn into a pulper.
