• the filled tubular bag is lifted relative to the folding device, and the two folding members of the folding device are moved horizontally inwards in order to press the wrapping material tight against the product surface.
• the present invention is therefore based on the object to provide a vertical bagging machine of the type specified, which works very fast, while allowing a largely precise folding and welding of the Hüllstoffs in the upper Schlauchlessnessend Scheme.

• the present invention relates to the folding of the Hüllstoffs on the surface of the filling material located in the open-top tubular bag and the production of the transverse weld during this continuous movement of the Hüllstoffs down.
• it is possible to perform the folding (by raising the filled with the contents, open-topped tubular bag) of Hüllstoffs on Golfgutober Structure and producing the transverse weld without stopping the downwardly moving Hüllstoffs, so that the machine can work much faster than a corresponding discontinuous machine in which a corresponding stop is required.
• the machine is designed so that during the Emwartsfar the welding jaws of Quernahtsch spavorraum and the folding mechanism of the folding device to the respective end point almost no relative movement between the welding jaws and Hullstoff takes place at the upper welding jaw contact point. This is achieved by matching the downwards movement of the envelope material and the inward movement of the welding jaws and folding members accordingly. Since the filler is moved inwardly by the movement of the welding jaws, a relative movement between the jaws and the hull material can be virtually avoided during this period of time, whereby the risk of damage to the hull is eliminated by the movement of the welding jaws.
• the continuous downward movement of the Hullstoffschlauches by the folding and welding operations should not be affected.

• this process takes place during the phase of inward movement of the welding jaws and folding members, in which the only moving unit for lowering the cross seam welding device, folding device is in its upper end position, because of the inward movement of the inward movement of the welding jaws caused by the inwardly moving welding jaws Hüllstoffs no relative movement between Hüllstoff and welding jaws occurs. Only after the welding jaws and folding elements have almost reached their inner end position, the only moving unit begins to lower.

In. The latter case, it may have a welding device for creating the upper transverse weld and a welding device for creating the lower transverse weld.
• the folding device can be formed independently of the transverse seam welding device or can form a unit together with it or be fastened to the transverse seam welding device. Furthermore, the cross seam welding device itself can take over the function of the folding device, so that in this case no separate folding device must be provided.
• the folding device can be formed by the welding device for producing the upper transverse weld seam (relative to the lower tubular bag). In this case, by moving inwards the welding jaws of the welding ' direction for the creation of the upper transverse weld seam at the same time the envelope is folded over onto the product surface.
