PROBLEM TO BE SOLVED: To prevent a thread-shaped paste generated by a cobwebbing phenomenon from sticking to a paper, when a viscous paste is applied to a paper such as an envelope or a document. SOLUTION: When an envelope 1 is separated from a paste-applying part 10a by means of a roller 50b after a paste is applied to the envelope 1 under such a state that the envelope 1 and the paste applying part 10a remain in contact with each other, air is blown to a space formed between the envelope 1 and the paste applying part 10a from an air blowing part 10. In this way, when the envelope 1 is separated from the paste applying part 10a, a thread- shaped paste generated between the paste which happens to be viscous and is applied to the envelope 1 and the paste applying part 10a due to a cobwebbing phenomenon, is sucked by a suction belt 81 with the help of the air blown from the air blowing part 70. Further, the thread-shaped paste is separated from the envelope 1 by moving the area, to which the thread-shaped paste sticks, of the suction belt 81 in a direction where the area leaves the envelope 1.
