Abstract: A device is provided for tearing off a series of perforated paper sheets and folding the detached paper sheets. The device is composed of a frame, at least two paper feeding rollers, at least three paper folding rollers, a plurality of paper guiding plates, at least one paper confining element corresponding in location to the paper folding rollers, and a linking member consisting of a transmission belt, a paper feeding wheel and a paper folding wheel. The transmission belt is driven by a driving unit to actuate the paper feeding wheel and the paper folding wheel, which in turn actuate the paper feeding rollers and the paper folding rollers.
