Claims
- 1. The process for producing paper reels from a paper web comprising:
calendering the paper web; longitudinally cutting the paper web into partial webs; and winding the partial webs into paper reels, wherein the calendering, longitudinal cutting, and winding occurs on-line and without intermediate winding.
- 2. The process in accordance with claim 1, said process further comprising:
forming a narrow strip from the paper web; guiding the narrow strip into an on-line winding device; and widening the narrow strip to an entire width of the paper web.
- 3. The process in accordance with claim 2, wherein, after the widening of the narrow strip, the longitudinal cutting occurs on the entire width of the paper web, and the process further comprises:
guiding the longitudinally cut partial webs onto winding cores.
- 4. The process in accordance with claim 3, wherein, substantially immediately before being guided onto the winding cores, the process further comprises cutting the partial webs in a crosswise direction.
- 5. The process in accordance with claim 3, wherein before being guided onto the winding cores, the process further comprises accelerating rotation of the winding cores to a web travel speed.
- 6. The process in accordance with claim 5, wherein said process is performed in an apparatus that includes a first and a second king roll arranged to form a winding bed, in which at least the second king roll is driven, and said process further comprises:
guiding the paper web over the first king roll; positioning the winding cores in contact with the second king roll and at a distance from the first king roll, whereby the acceleration of the winding cores occur; and winding the paper reels in the winding bed.
- 7. The process in accordance with claim 1, wherein said process is performed in an apparatus including first and second winding beds, and said process further comprises:
winding a first batch of paper reels in the first winding bed; winding a second batch of paper reels in the second winding bed, wherein the batches are wound alternatingly.
- 8. The process in accordance with claim 7, wherein, upon completion of one of the batches of paper reels, the process further comprises:
accelerating rotation of the winding cores for the other batch of paper reels to a web travel speed; separating the partial webs from the completed batch of reels; and transferring the partial webs to the accelerated rotating winding cores.
- 9. The process in accordance with claim 7, wherein the apparatus includes a common king roll and two other king rolls arranged to from the first and second winding bed, and, upon completion of one of the batches of paper reels, the process further comprises:
lifting the completed paper reels off of the common king roll; and allowing the completed rolls to exit on one of the other king rolls while the other batch of paper reels are being wound in the other winding bed.
- 10. An apparatus for producing paper reels comprising:
a paper machine; a calender; a longitudinal cutting device; and a reel winding device, wherein said paper machine, said calender, said longitudinal cutting device, and said reel winding device are successively arranged in a web run direction.
- 11. The apparatus in accordance with claim 10, wherein said paper machine, said calender, said longitudinal cutting device, and said reel winding device are arranged to form a continuous paper web travel path.
- 12. The apparatus in accordance with claim 10, wherein said longitudinal cutting device comprises a displaceable cutting device arranged behind said calender in said web run direction.
- 13. The apparatus in accordance with claim 10, wherein said longitudinal cutting device comprises knives and an opening device, which are arranged so that the opening mechanism moves the knives away from one another to form an insertion path.
- 14. The apparatus in accordance with claim 13, wherein said displaceable cutting device and said opening mechanism fixedly positioned relative to one another.
- 15. The apparatus in accordance with claim 10, further comprising a crosswise cutting device, wherein, behind said winding device in the web run direction, a disposal path is formed, and said crosswise cutting device is arranged before the disposal path.
- 16. The apparatus in accordance with claim 10, further comprising an ejection device, wherein the winding device comprises a king roll arranged to form a part of two winding beds with at least two other king rolls, and said ejection device is arranged to controllably lift completed paper reels off said common king roll and to allow the completed paper reels to exit on one of the at least two other king rolls.
- 17. The apparatus in accordance with claim 16, further comprising an auxiliary device located in each winding bed to hold a set of winding cores at a distance from said common king roll for acceleration to a web travel speed.
- 18. The apparatus in accordance with claim 10, further comprising a pulper arranged behind the winding device.
- 19. 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 winding cores against one of said first and said second king roll and to maintain a distance between the winding cores and said common king roll.
- 20. The apparatus in accordance with claim 19, wherein said apparatus is arranged to wind reels in only one winding bed at a time.
- 21. The apparatus in accordance with claim 20, further comprising an ejection device arranged to eject completed rolls from said only one winding bed.
- 22. The apparatus in accordance with claim 19, wherein, as the winding of the reels in the only one winding bed nears completion, said apparatus is arranged to accelerate empty winding cores in the other winding bed to a web travel speed via the auxiliary devices and one of the first and second king rolls.
- 23. The apparatus in accordance with claim 19, further comprising a calender alternatingly coupled to said first and said second winding beds.
- 24. The apparatus in accordance with claim 23, further comprising a paper manufacturing machine coupled to said calender.
- 25. The apparatus in accordance with claim 24, further comprising a tail cutter positioned between said calender and said longitudinal cutter to facilitate threading of an entire width of the web.
- 26. The apparatus in accordance with claim 25, further comprising a pulper arranged after said first and said second winding beds in the web travel direction.
