PROBLEM TO BE SOLVED: To provide a longitudinally folding device capable of adjustment and easy to adjust without stopping a printing machine during operation. SOLUTION: A roller above a triangular plate is arranged above a triangular plate 2 provided at an entrance of a folding machine 1 for guiding and inducing a web 4 transferred from a printing device in a preceding process to the triangular plate 2. The roller 5 above the triangular plate is changeable in relative position to the triangular plate 2 by movement of bearings 6 at both sides in the cross direction of the pivotally supported web (in the vertical direction, shown in Fig.) via any type of mover 7 to move the travelling web 4 apart from or close to the triangular plate 2. |
