Definitions
- the present invention relates to a sack making apparatus and a method for the production of open sacks as well as open sacks produced therewith.
- a sack-making device is used in particular on or for an FFS system (form-fill-seal) in order to produce the required open sacks on site when filling bulk materials into open sacks. It is also possible to produce sacks in stock with the sack-making device according to the invention and to temporarily store them for later use.
- a bottom seam is transported. At a bottom seam welding station, a bottom seam is first introduced into the tubular film.
- the tubular film is a bag length
- Tube film introduced while at the same time just below the bottom seam is cut through the tubular film, creating the first open bag.
- the open bag is filled from above with the contents and a
- Welding device is welded to the headboard.
- the method works in principle, but has the disadvantage that at least a small film supernatant is present at the bottom seam.
- the two layers of the film supernatant together form a receiving space or a plurality of receiving spaces or cavities, on or in which dirt particles or else to be filled
- the bag-making device according to the invention serves for
- Production of open sacks includes a storage device with a supply of bag film.
- a control device is used for control.
- at least one transport device is provided for transporting the bag film and / or the bag body along a (predefined) transport path. It is
- a welding device with welding means for introducing (at least) a bottom seam in the bag film.
- a cutting device with (at least) a cutting means for separating a predetermined film length of the bag film to form a
- the control device is designed and configured to control the transport device in such a way that a relative movement of the bag body and the bag film relative to each other is effected and in front of the
- the control device is set up and designed to control the transport device and the welding means such that the welding means extend at least as far as the bottom end of the bag body during welding of the (edge-sealed) bottom seam and / or extend beyond.
- the cutting means prefferably be arranged and effective at least during the cutting of the bag film within a longitudinal section of the transport path, in which case
- welding means extend at least as far as the bottom end of the bag body. This can be ensured by the fact that the cutting means during
- Cutting is located in the same longitudinal section as the
- the bag film is moved back to produce the (predetermined) distance after cutting and before welding.
- Welding device arranged in an overlapping longitudinal portion of the transport path and effective.
- the bag body within the bottom seam is welded to the bottom end of the entire surface. Then there are at the end not two layers of the film from where and between which can accumulate dust. Thus, a weld without outer film projection is produced.
- Transport path is moved relative to the bag film, while the bag film z. B. is not moved forward. Then the bag body is advanced by the predetermined distance until the bottom end arrives at the welding means and at
- Welding is an edge-tight welding of the bottom seam or a down to the bottom end of the bag body extending full-surface bottom seam is generated.

- Attach the filling system It is also possible that two or more hitches are provided.
- the inventive method is used for the production of
- Open sacks from a supply of bag film wherein the bag film is transported along a transport path and wherein with (at least) a cutting means of a cutting device, a predetermined length of film is separated from the bag film to to form a bag body of an open bag.
- the bag film is moved relative to the bag body. By welding, a bottom seam is introduced to the bottom end of the bag body to form an open bag.
- the method according to the invention also has many advantages.
- the process can be used to produce open-sacks that meet high hygienic standards.
- the bag film is withdrawn from the separated bag body in particular defined before the bottom end is welded. It is also possible that the bag film is withdrawn from the separated bag body Undefined, for example, by the associated drive is activated for a certain period of time or the like. During the subsequent further transport of the bag film, for example, an optical sensor or the like can detect the leading edge of the bag film again and thus a defined positioning of the
- the film or the bag body is fixed before the separation of the bag body.
- the bag film is in the region of the bag body and it is also fixed the bag film in front of it.
- Such a fixation can be done, for example, by using appropriate
- the fixation of the bag film in front of the bag body is canceled before the bag film is withdrawn.
- the bag body remains fixed while the

- the bag body of the offset bag may include gussets and / or corner welds.
- Open sacks have no film overhangs at the bottom seam where particles or dirt can stick.
- the film feed of the bag film is up to about one bag length over the cutting plane of the
- the bag body is cut off from the bag film with the cutting device. It follows a release of the
- the finished bag body is transported with the open side forward in the transport direction of the transport path.
- the bag film is then moved forward again, so that a (new) bag body is again completely in front of the cutting plane.
- the feed of the bag film can be sensor-controlled or, for example via a servo drive or the like, so that a well-defined positioning of
- the bag making apparatus may include a film storage, so that a continuous operation of the film roll or
