METHOD AND DEVICE FOR REPAIR OF WEB

摘要: PURPOSE:To repair a minor defect of web such as hole automatically, effectively, and precisely by affixing patch to the defect. CONSTITUTION:The position 1 is sensed, on basis information result from sensing, feed decelerated way rewinding roll 10a made device 6, passage sensed sensor 8 in this condition. On sensing signal thus obtained, 15 with adhesives standby protrusive state an exfoliation edge 13 downstream pressed over-part pressure roller 14. Thus affixation made, repaired.
