    摘要： A paper folding device wherein two wing members are supported for pivotal movement between an open and a closed position, with a gap formed between the two wing members in the closed position. A sheet of paper to be folded is fed into the gap by rollers until the forward edge of the paper hits an adjustable stopper in the gap, so that as the sheet is farther moved by the rollers, a portion of the sheet outside the gap is bent, and the bent portion is nipped and then folded by the rollers. A sound absorber is so arranged adjacent each of the two wing members so as to absorb the sound caused by the forward edge of the sheet of paper striking the stopper inside the gap.
