Method and apparatus of manufacturing a hygiene paper product
Method of manufacturing a hygiene paper product in form of a continuous paper web (W) of sheets partly separated by perforation lines ( 9 ) and wound to a log of predetermined longitudinal length, providing a continuous paper web (W), moving the continuous paper web in a direction of its longitudinal extension, providing at least one embossed pattern on the continuous paper web, providing in the area of an embossing station at least one mark ( 6, 7 ) onto the continuous paper web, which mark ( 6, 7 ) is in register to the embossed pattern, sensing the mark and controlling perforating means for registering the perforation lines ( 9 ) with the embossed pattern thereby imparting perforation lines to the continuous paper web in predetermined longitudinal distances, winding up the resulting web to logs, and cutting the log into rolls.
1. A method of manufacturing a hygiene paper product, comprising:
providing a continuous paper web, the continuous paper web having sheets partly separated by perforation lines and wound to a log of predetermined longitudinal length;
moving the continuous paper web in a direction of the paper web's longitudinal extension;
providing at least one embossed pattern on the continuous paper web;
providing in an area of an embossing station at least one mark onto the continuous paper web, the at least one mark being in register to the embossed pattern, the at least one mark being applied to a back side of paper plies opposite to an embossing side;
sensing the mark and controlling perforating means for registering the perforation lines with the embossed pattern thereby imparting perforation lines to the continuous paper web in predetermined longitudinal distances;
winding up the resulting web to logs; and
cutting the log into rolls.
2. The method according to claim 1 , wherein the at least one mark or another mark is used for registering saw cuts in correlation to the embossed pattern.
3. The method according to claim 1 , wherein the at least one mark is embossed onto the continuous paper web.
4. The method according to claim 1 , whereby a marking substance is applied onto the paper web.
5. The method according to claim 4 , wherein the at least one mark is an ink or coloured adhesive.
6. The method according to claim 3 , wherein a substance is applied onto the embossed mark.
7. The method according to claim 6 , wherein the substance is an ink or a coloured adhesive.
8. The method according to claim 1 , wherein the at least one mark is a dot-mark or MD-line-mark for cutting control and/or a dot-mark or a CD-line-mark for register-control of perforation.
9. The method according to claim 1 , wherein the at least one mark is applied to a front side of the continuous paper web being the embossing side.
10. The method according to claim 1 , wherein the mark is detected on the front side of a continuous paper web.
11. The method according to claim 6 , wherein the embossed pattern and the embossed mark(s) is/are applied by the same embossing means.
12. A method of manufacturing a hygiene paper product, comprising:
providing a continuous paper web, the continuous paper web having sheets partly separated by perforation lines and wound to a log of pre-determined longitudinal length;
moving the continuous paper web in a direction of the paper web's longitudinal extension;
providing at least one embossed pattern on the continuous paper web;
providing in an area of an embossing station at least one mark onto the continuous paper web, the at least one mark being in register to the embossed pattern, and the at least one mark is applied to a cookie-area of the log;
sensing the mark and controlling perforating means for registering the perforation lines with the embossed pattern thereby imparting perforation lines to the continuous paper web in predetermined longitudinal distances;
winding up the resulting web to logs; and
cutting the log into rolls.
13. The method according to claim 12 , wherein two different marks are applied to one and the same cookie-area at least one end of the log.
14. The method according to claim 12 , wherein one of two different marks is applied to one cookie-area of the log and the other mark to the other cookie-area of the log.
15. The method according to claim 12 , wherein the mark or another mark is used for registering saw cuts in correlation to the embossed pattern.
16. The method according to claim 12 , wherein the at least one mark is embossed onto the continuous paper web.
17. The method according to claim 12 , whereby a marking substance is applied onto the paper web.
18. The method according to claim 12 , wherein the at least one mark is an ink or coloured adhesive.
19. The method according to claim 16 , wherein a substance is applied onto the embossed mark.
20. The method according to claim 19 , wherein the substance is an ink or a coloured adhesive.
21. The method according to claim 12 , wherein the at least one mark is a dot-mark or MD-line-mark for cutting control and/or a dot-mark or a CD-line-mark for register-control of perforation.
22. The method according to claim 12 , wherein the at least one mark is applied to a front side of the continuous paper web being an embossing side.
23. The method according to claim 12 , wherein the mark is detected on the front side of the continuous paper web.
24. The method according to claim 19 , wherein the embossed pattern and the embossed mark(s) is/are applied by the same embossing means.
