Method and apparatus for the winding up of a paper web to form a roll

A method for winding up a paper web to form a paper roll, the method comprising the steps of:

• accelerating a first reel spool to the speed of the web to be wound and moving the first reel spool into a stationary winding position wherein the first spool forms a nip with a rotatable press drum;
• guiding the leading end of the web of paper around the press drum to wind onto the rotating first spool;
• maintaining the first spool in the stationary winding position essentially during the entire winding process;
• pressing the press drum against the winding surface of the developing paper roll on the first reel spool;
• and the press drum being displaceable without change in directional orientation relative to the paper roll for applying and regulating line pressure between the press drum and the developing paper roll by pressing the press drum against the winding surface of the paper roll throughout substantially the entire winding process;
• during the entire winding process, introducing a torque into the axis of the first reel spool;
• shortly before completion of the winding, moving the first reel spool with the paper roll wound thereon out of the stationary winding position directly into a stationary end position spaced from the stationary winding position wherein completion of winding is performed, accelerating a second reel spool to the speed of the web and then bringing the second reel spool into the stationary winding position wherein the press drum forms a nip with the second reel spool.

Apparatus for winding up a paper web to form a paper roll, the apparatus comprising:

• a first reel spool on which a web is to be wound;
• means for supporting the first spool at a first, stationary start of winding position;
• means for rotating the first reel spool to the speed of the web to be wound;
• web guiding means for guiding the leading end of the web around the rotating first spool;
• means for moving the first spool from the first, stationary start of winding position directly to a second, stationary completion of winding position spaced from the first winding position after the first spool has reached a first wound layer thickness and means for continuing rotation of the first spool in the second position;
• a rotatable press drum in engagement with the winding surface of the first spool throughout substantially the entire winding process;
• a carriage supporting the press drum to be movable toward and away from the first reel spool, the carriage being moveable for retaining the press drum in engagement with the first winding reel spool as the spool moves from the first to the second stationary positions;
• the first spool and the press drum being continuously maintained in the same directional orientation as the spool and press drum move relative to each other;
• means for accelerating a second reel spool to the speed of the web to be wound and for bringing the second reel spool into the first, stationary start of winding position while the first spool is in the second position, wherein the web guiding means guides a new leading end of the web to the second reel spool.
