The present invention relates to an apparatus? zur * Elnfaltuhg eini: flap from one of one Box casing axially straight protruding layer to a Location that covers' the box fatigue, the device .; Means to * display the boxes on one having,'

The gomSTS device of the invention is characterized in that the folding curve is rotatably attached to a shaft is that in relation to the advance direction of the Box is arranged at right angles and that it has a string curve that engages the outside the flap is arranged and with its folding anf: Un <jt, and has an extremely zy-linder-like curved surface, to continue the folding of the flap dJänt,

Furthermore, the device according to the invention preferably a pressure sole attached directly after the folding curve in the direction of advance of the boxes, Pressure rail or the like, which is arranged to fold the folded flap in a bent over To hold position until it is attached with the help of means known per se, with dias © pressure sole, pressure splint, or the like to bring about further impressions the folded flap can be arranged.

The drawings show how boxes 1 are shown in Arrow direction A. The device has a folding curve 3 which is rotatable is attached to a shaft 4. In the example shown, this folding curve becomes 3 used to fold the last folded box flap 5 of the closure. The other three flaps of the box are already folded in. The folding begins with the help of the side curve 6 of the folding curve. With this folding. Should in that shown in Fig. 1 Location just started. The folding curve moves in the direction of arrow B around the center of Helle 4 Around. When the curve reaches the position shown in Pig, 2, the side curve is 6 of the folding curve makes contact with the outside of box flap 5 free. the Folding is then carried out by the cylinder-like, outer curve surface 7 of the folding curve continued, which ends the folding. After this If the flap 5 is completely folded in, or exactly before, it is inserted under the pressure bar 8. This pressure rail can thus be arranged in such a way that it is a further pressing in of the folded Flap 5 causes. Finally will

of course flap 5 attached in the folded position. This is done in a way that is known per se Way, for example with the help of adhesives, heat sealing or push-in flaps. For this reason, no more detailed description is given in the drawings.

The invention is of course not limited to the exemplary embodiment described above, but can be modified within the scope of the following claims. Scnit can of course the shape of the curve in relation to the speed at which the machine is running work should be modified. Is essential here just that the folding is divided into two phases being the first with the help of the side curve and the second with the help of the sweeter, cylinder-like curved surface of the folding curve ,
