Abstract

The device for folding packaging bags and letter envelopes involving closure flaps with or without closure flaps and with or without self-adhesive strips entails the bag or envelope moved against a stationary stop. The flap and counter flap are positioned by suction components (7,9) arranged on a counter flap roller (6) and a closure flap roller (8). The radius of the counter flap roller supporting the corresponding suction component is at least partly reduced. The counter flap roller is so securable that a folding product is movable past it to the stationary stop without contact or virtually so.
