A process for producing paper reels from a paper web comprising:
- calendering the paper web;
- forming a narrow strip from the calendered paper web;
- guiding the narrow strip to a winding device and into a disposal device;
- widening the narrow strip to an entire width of the paper web;
- longitudinally cutting the entire width paper web into partial webs;
- and
- winding the partial webs into paper reels,
- wherein the calendering, longitudinal cutting, and winding are consecutively performed without intermediate winding.
An apparatus for producing paper reels comprising:
- a paper machine;
- a calender;
- a longitudinal cutting device;
- a reel winding device;
- a disposal device arranged downstream of said reel winding device, relative to a web run direction,
- wherein said paper machine, said calender, said longitudinal cuffing device, and said reel winding device are successively arranged in the web run direction to form a continuous paper web travel path between said paper machine and said reel winding device.
An apparatus comprising:
- a common king roll;
- first and second king rolls each arranged adjacent said common king roll to form first and second winding beds;
- a longitudinal cutting device arranged before said first and second winding beds in a web travel direction;
- and
- auxiliary devices arranged in each of said first and said second winding beds which are positionable to hold empty winding cores against one of said first and said second king roll and to maintain a distance between the empty winding cores and said common king roll.
