Definitions
- the invention relates to a method for the production of foil bags, which have V-shaped inserted and offset from the upper edge gussets and a reclosure in a head-side opening.
- the reclosure can be designed as a pressure lock (zipper) or as a slide fastener (slider).
- a pressure closure consists of two superimposed and without slider releasably connected profile strip, each having a strip-shaped carrier and mutually engaging locking strips.
- the profile strip forming the male part of the pressure closure is usually fastened to the inner surface of the film bag with sealing seams which extend on both sides of the locking strip.
- the female profile forming the corresponding profile strip is connected to at least one sealed seam above the other locking strip with the other wall surface of the bag.
- a pusher closure also consists of two profile strips which are connected at their lower edge by a frangible line of weakness. Further, a slider is provided, which engages over the closing edges of the profile strip like a rider.
- the initially flat foil pouches can be loaded into bag filling devices with filling material.
- the filling takes place at the top of the bag, wherein the contents are introduced either into an opening, which is initially still present between the reclosure and a front side of the film bag, or through the opened reclosure.
- Foil bags with the described features are used, inter alia, for packaging animal feed.
- a method for the production of flat film bags with the described features is known from DE 10 2005 026 149 A1.
- the known method are in a flat foil sheet punched, which delimiting the upper end of the laterally formed gussets.
- reclosure strips are applied transversely to the web direction on the film web and connected at the ends of the film web.
- the film web is then passed through a folding station, in which the film web is folded in a tube and gussets are inserted.
- the reclosures are connected to a front face of the bag by incorporating the upper end of the gussets, and the superimposed layers of film are sealed with seal seams to form a bag-string consisting of bag-shaped sections from which film bags are separable.
- the invention has for its object to modify the method for producing reclosable side gusset bag so that the risk of production disruption due to a non-exact web run is minimized.
- the object and solution to this problem is a method according to claim 1 with the following method steps: (a) at least one first film strip is to be provided with cut outs in peripheral areas;
- side folds are formed by C-shaped folding of the edge regions, wherein the cut-outs delimit respectively the upper end of the side folds;
- the superimposed film layers are connected with further sealing seams to a bag-strand consisting of bag-shaped sections, from which foil bags can be separated.
- the flat film bags are made of two film strips, wherein the first film strip is folded at the edges C-shaped and gusset areas are formed, which are interrupted by punching.
- the cutouts each limit the top of the gussets.
- the punched holes can be introduced into the flat foil strip before it passes through a folding station and the gussets are formed. It is also conceivable, however, that first the gussets are formed and then the gusset areas are punched out at predetermined intervals.
- the reclosure strips are placed on the film strips folded at the edge and connected to the film strip over their entire length. The connection is made by one or more sealing seams, which are the upper edge of the gussets close.
- the upper edge of the gussets by separate measures, eg. B. by applying adhesive labels, is closed.
- a film web is pulled off a roll and separated into at least two film strips.
- the first film strip is folded in the edge regions in accordance with method step b), and reclosing strips are applied in accordance with method step c).
- the second film strip is spatially separated from the first film strip using baffles, brought into registration with the first film strip and fed to the first film strip in step d) and joined at the edges with the gussets of the first film strip to form a gusseted tube.
- the cutouts delimiting the upper edge of the gussets can be introduced into the film web before the film web is separated into the film strips.
- the method according to the invention readily permits a double-use or multi-use production, in which two or more bag strands are produced parallel to one another from a flat film web according to the described method. In a two- or more-use mode of operation, the film web is separated into a plurality of film strips, wherein associated first and second film strips are each adjacent to each other.
- the punch-outs which interrupt the gusset areas of the first film strip, are expediently introduced into a stationary web section of the film web in cyclic operation.
- the provided with the punched film web is then separated in a continuous pass in the film strips.
- the clocking mode and the continuous mode are coupled using a band memory.
- the first film strip is also suitably folded in continuous operation in process step b) and connected in process step d) with the tapered second film strip.
- the application and fastening of the reclosing strip (method step c)) follows in clockwise operation on a stationary section of the film strip. Between the cyclically operated workstation and the upstream and downstream work stations, which are continuously traversed by the film strip, tape storage are provided.
- the outer edges of the gussets can be stiffened by attaching longitudinal sealing seams. Further, the edges of the side-folding bag formed by the second film strip applied prior to step d) are trimmed to give the bag-string the required dimensional stability.
- a reclosure strip press fasteners can be used, which consist of two superposed and releasably connected profile strips, wherein the profile strips each have a strip-shaped support and mutually engaging locking strips.
- slide fasteners which consists of two superimposed and with a releasably connected profile strip and a slider, the closing edge of the profile strip like a rider, consist.
- Fig. 1 shows a process scheme for the production of foil bags, the V-shaped inserted and deposited at the top gussets and a
- FIG. 2 shows the attachment of the reclosure strip in the method shown in Fig. 1 and
- a film web 1 is pulled off a roll 2 and separated into at least two strips 3, 4.
- the first film strip 3 contains in peripheral areas punched-5, which have been previously introduced into the film web 1.
- Gaps 6 are formed by folding the edge regions in a C-shaped manner, with the punched-out portions 5 respectively bounding the upper end of the side folds (FIG. 2).
- Re-entrapping strips 7 are applied to the film strips 3 transversely to the web direction and extend across the width of the film strip 3 folded in the edge regions and embed and close the top end of the side pleats 6.
- the second film strip 4 separated from the film web is spatially separated from the first film strip 3 using deflection devices 8 and brought into overlap with the first film strip 3 by a parallel offset.
- the second film strip 4 is applied to the first film strip 3, wherein the film strip 4 tapers in the web direction and is connected at the edges with the side folds 6 of the first film strip 3 to a gusseted tube 9.
- the outer edges of the gussets 6 can be stiffened by attaching longitudinal sealing seams. Further, the edges of the gusseted tube 9, at least the edges formed by the applied second film strip 4, are trimmed.
- the film layers lying on top of each other are connected with further sealing seams to a bag strand consisting of bag-shaped sections, from which foil bags can be separated.
- the method illustrated in FIG. 1 is composed of cyclically operated process sections and process sections operated in continuous operation.
- the provided with the punched film web is then separated in a continuous pass in the film strips 3, 4.
- a tape store 10 is provided in which the film web enters intermittently and from which the film web is drawn off at a predetermined, constant web speed.
- the first film strip 3 is folded in a continuous pass and later connected to the incoming second film strip 4 in continuous operation.
- the application of the reclosure strip 7 takes place cyclically on a stationary portion of the film strip 3.
- the method illustrated in FIG. 1 permits a double-use or multi-use production, in which two or more bag strings are produced simultaneously from the flat film web 1 according to the method described in parallel.
- the film web is separated into a plurality of film strips, wherein associated first and second film strips 3, 4 are each adjacent to each other.
- the process product shown in Fig. 3 contains in the head area a reclosure strip 7 in the form of a snap closure.
- This consists of two superimposed and detachably connected profile strips, each having a strip-shaped carrier and mutually engaging locking strips.
- the method according to the invention also readily permits both the processing of slide fasteners, which consist of two profiled strips lying on top of one another and detachably connected to one another, and a slider which engages over the closing edges of the profiled strips in a rider-like manner, as well as of hook-and-loop fasteners and similar closure systems.
