Definitions
- the invention relates to a method and an apparatus for producing film bags, the V-shaped inserted gussets and a reclosure with a slider in a head-side filling opening.
- the reclosure of the foil pouch consists of two profile strips and a slide coupling the profile strips.
- One of the profile strips is connected to a front side of the film bag and the other profile strip after filling of the film bag connected to the other front side.
- the initially flat foil bags are loaded into bag filling devices with filling material. The filling takes place at the head of the bag. The contents are introduced into an opening which is still present between the reclosure and a front side of the film bag. Thereafter, this opening is closed by a sealed seam.
- Foil bags with the described features are used, inter alia, for packaging animal feed.
- Foil bags with the described features are known from DE 202 07 333 U1. Their production is complicated. Following the bag production, the reseals are applied in a downstream part of the plant. For this purpose, a film section of the already manufactured film bag is unfolded in the head region of the bag, placed a reclosure on the underlying film web and connected to this. Thereafter, the unfolded film section must be folded back and the missing sealing seams are attached.
- the devices required for the application of reclosures must perform several steps and have a significant footprint. There is a need to integrate the application of reclosures while avoiding a downstream part of the plant in conventional bag-making process.
- the invention has for its object to provide a method in which the application of the reclosures during the continuous web advance of a flat film web takes place before the bag forming.
- the subject matter of the invention and solution to this problem is a process for producing film bags according to claim 1.
- the process according to the invention comprises the following process steps:
- the film web is passed through a folding station, in which the film web is folded and front surfaces and gussets are formed;
- the invention is based on the idea of applying the reseals to the flat film web before the film web passes through a folding station, in which it is folded and gussets are formed.
- the application of the reclosures according to the invention can be integrated into existing bag-making systems, the method according to the invention making use of the punching devices and folding devices already present in a bag-making machine. In this case, however, the technical problem is to be solved that the reclosures during transport of the film web through the system, in particular in the Umfalt coupleden move, because the reclosures are initially connected only at the ends of the film web. There must be an opening between the profile strips of the reclosure and the film web so that the bags can be filled at the head end.
- weakening lines are introduced into the flat film web transversely to the web longitudinal direction, which are arranged at the level of the window-shaped recesses and extend over the web width with the proviso that between the weakening lines and the window-shaped recesses in each case a 5 mm to 50 mm wide non-weakened film area remains.
- the weakening lines are, for example, a perforation produced by punching or a weakening device produced by means of laser technology. line.
- the film web is guided in the folding station in such a way that the edges of the folding tools rest against the non-weakened film areas between the perforation / weakening line and the recesses.
- the folding of the film web into a tubular web takes place by using triangular folding sheets, the window-shaped punched-out portions being guided centrally over the triangular sheets.
- the bags can be separated from the bag string in various ways.
- An embodiment of the method according to the invention provides that the bags are separated by a separating cut of the bag string, wherein between the cutting edge and the adjacent weakening line remains a strip-shaped portion which covers the reclosure.
- the strip can be used as a tamper-evident closure if the double-layered strip is sealed with a transverse seal after filling the foil bag at its upper edge.
- the top strip must be cut off, exposing the reclosure at the upper edge of the foil bag. If the sealing seam of the waste strip is undamaged, it is ensured that the foil bag has not previously been opened.
- the bags can also be separated along the lines of weakness of the bag string by a tensile force is applied, for example by a train delay on the bag to be separated in the web longitudinal direction.
- the bags are torn from the bag string along the line of weakness.
- At the bottom end of the demolished foil bag remains a remnant, which can be used as a material for forming and sealing the bag bottom.
- a further embodiment of the method according to the invention provides that the bags are separated from the bag strand by a separating cut and that a strip-shaped section consisting of two film layers remains between the cut edge and the re-closure, which covers the re-closure, and that the foil layers covering the re-closure be severed from the bag with a knife to expose the slide of the resealer.
- supernatant film sections are separated after bag folding and welding by folding and cutting. This results in smooth film edges, which are not bevelled at the longitudinal sealing seams.
- the invention is also an apparatus for performing the method with
- an unwinding station for removing a flat film web from a film roll
- a feed device for prefabricated reclosures consisting of in each case two profiled strips which lie on one another and connected to one another and a slider which engages over the closing edges of the profiled strips in a rider-like manner
- a folding station with folding devices for double-layer folding of the film web and for inserting V-shaped side folds
- the punching device arranged in front of the folding station comprises additional punching tools which insert slide punched holes in the planar film web, and wherein a device is provided between the punching device and the folding station which positions the reclosures transversely to the web longitudinal direction on the flat film web so that the slides of the reclosures lie in the assigned Schieberausstanzache.
- Fig. 1 shows the block diagram of a plant for the production of foil bags, the V-shaped inserted gussets and a
- FIG. 2 shows a detail of a flat foil web with punched-out portions introduced according to the invention before the
- the plant shown in FIG. 1 comprises an unwinding station 1 for removing a flat film web 2 from a film roll 3, a punching device 4, a feed device 5 for prefabricated reclosures 6, a folding station 7 with folding devices for double-layered folding of the film web 2 and for insertion V-shaped gussets, sealing stations 8 for transverse sealing and longitudinal sealing of the folded material web and a station 9 for separating foil bags from the material web.
