PROBLEM TO BE SOLVED: To provide a pasting device for preventing wastefulness of a paste liquid and paste sticking to a downstream side heating plate, capable of reducing a paste fixation in a pasting roll, and capable of also easily recovering-processing a trimming piece on both ends of a corrugated board sheet.SOLUTION: A pasting device 10 comprises a storage tank 1 for storing a paste liquid 2, a pasting roll 3 partially soaked in the paste liquid stored in the storage tank, a doctor roll 4 for uniformly adjusting a film thickness of the paste liquid stuck to the pasting roll and a pair of paste dams 5 for regulating a sticking width of the paste liquid to the pasting roll, and coats the paste liquid stuck to the pasting roll on central core paper W1 of the corrugated board sheet W. The respective paste dams comprise a pair of dam parts 51 mutually separately positioned in the width direction of the pasting roll, and a paste-unstuck area K of not sticking the paste liquid sandwiched between the pair of dam parts is formed on an outer peripheral surface of the pasting roll in response to a trimming part T on both ends of the corrugated board sheet.SELECTED DRAWING: Figure 5 |
