Claims
- 1. A process for producing a wound roll that is wrapped on its circumference, comprising:winding a material web into the wound roll; attaching a wrapping web to the material web at a location remote from the wound roll, whereby the material web guides the wrapping web toward the wound roll; and winding the wrapping web attached to the material web around the circumference of the wound roll.
- 2. The process according to claim 1, wherein, before winding the material web on the roll, the process further comprises:cutting the material web in a longitudinal direction, wherein the wrapping web is attached to the material web before the cutting.
- 3. The process according to claim 1, further comprising attaching a trailing edge of the wrapping web to the material web.
- 4. The process according to claim 3, further comprising jointly winding the wrapping web and the material web around the circumference of the wound roll.
- 5. The process according to claim 3, further comprising gluing the material web to a surface of the wound roll in a vicinity of the attachment of the trailing end of the wrapping web to the material web.
- 6. The process according to claim 1, wherein the wrapping web includes a leading edge, and the attachment of the wrapping web to the material web comprises attaching the leading edge of the wrapping web to the material web, and the process further comprises:cutting the material web in a region downstream of the attachment of the leading edge of the wrapping web to the material web, thereby forming a trailing edge of the material web attached to the wrapping web and a leading edge of the material web; cutting the wrapping web to form a trailing edge of the wrapping web; and attaching the trailing edge of the wrapping web to the leading edge of the material web.
- 7. The process according to claim 6, further comprising attaching the trailing edge of the wrapping web to the circumference of the wound roll in a region upstream of the attachment of the trailing edge of the wrapping web and the leading edge of the material web.
- 8. The process according to claim 7, further comprising weakening the wrapping web in a region between a region of the trailing edge for attachment of the wound roll and a region of attachment between the leading edge of the material web and the trailing edge of the wrapping web.
- 9. The process according to claim 1, further comprising:attaching one of the material web and the wrapping web to a surface of the wound roll; and weakening the one of the material web and the wrapping web in a region after a region of the one of the material web and the wrapping web to be attached to the surface of the wound roll.
- 10. The process according to claim 9, wherein the weakening comprises perforating the one of the material web and the wrapping web.
- 11. The process according to claim 9, wherein the winding occurs in a winding device, and the process further comprises:ejecting the wound roll from the winding device, whereby the weakened one of wrapping web and the material web is torn off.
- 12. The process according to claim 1, wherein the wrapping web is composed of a plurality of wrapping webs arranged next to one another and laterally to a travel direction of the wrapping webs and positioned to at least partially overlap each other to form an overlap region, the process further comprising:positioning the overlap region so as not to align with an edge of the wound roll.
- 13. A process for a circumferentially wrapped wound roll in an apparatus that includes a material web delivery path, a winding device, and a packaging web dispenser having an output path arranged to feed a packaging web into the material web delivery path, the process comprising:feeding the material web along the material web delivery path toward the winding device; and feeding a packaging web along the output path of the packaging web dispenser into the material web delivery path.
- 14. The process according to claim 13, further comprising longitudinally cutting the material web fed along the material web delivery path downstream of a position at which the output path feed the packaging web into the material web delivery path.
- 15. The process according to claim 13, further comprising applying a first glue to the wrapping web in a region downstream of where the output path of the packaging web dispenser feeds into the material web delivery path.
- 16. The process according to claim 15, further comprising:forming a nip between the wound roll and a roller; and applying a second glue to one of the material web and the wrapping web in region before the nip.
- 17. The process according to claim 16, further comprising weakening the one of the material web and wrapping web in a vicinity of where the second glue is applied.
- 18. The process according to claim 17, wherein the one of the material web and wrapping web are perforated.
- 19. The process according to claim 13, wherein the apparatus further comprises a winding bed, and process further comprises:securing the material web at an inlet region of the winding bed.
- 20. The process according to claim 13, further comprising laterally moving a plurality of wrapping web rolls to form an overlap region extending in a web travel direction.
- 21. The process according to claim 20, further comprising longitudinally gluing the overlap region of adjacent wrapping webs.
- 22. The process according to claim 20, further comprising controlling a position of the overlap region so that it is not located at an edge of the wound roll.
- 23. An apparatus for producing a circumferentially wrapped wound roll, comprising:a material web delivery path; a winding device; and a packaging web dispenser having an output path arranged to feed a packaging web into the material web delivery path.
- 24. The apparatus according to claim 23, further comprising a longitudinal cutting device arranged within the material web delivery path; andwherein the output path is coupled to the material web delivery path prior to the longitudinal cutting device.
- 25. The apparatus according to claim 23, further comprising a first glue delivery station located in a region downstream of where the output path of the packaging web dispenser feeds into the material web delivery path.
- 26. The apparatus according to claim 25, further comprising:a nip formed between the wound roll and a roller; and a second glue delivery station located in a region before the nip.
- 27. The apparatus according to claim 26, further comprising a weakening device positioned in a vicinity of the second glue delivery station.
- 28. The apparatus according to claim 27, the weakening device comprising a perforation device.
- 29. The apparatus according to claim 23, further comprising:a winding bed; and a material web securing device located in an inlet region of the winding bed.
- 30. The apparatus according to claim 23, further comprising a plurality of wrapping web rolls which are laterally movable to the wrapping web travel direction and in which the wrapping webs are overlappingly positionable to form an overlap region.
- 31. The apparatus according to claim 30, further comprising a longitudinal gluing device that glues the overlap region.
- 32. The apparatus according to claim 30, further comprising a control device that ensures that the overlap region is not located at an edge of the wound roll.
