Definitions
- the invention relates to a bag according to the preamble of patent claim 1 and to a method and a device for producing a bag.
- the bags described above are suitable for a wide range of applications. Goods purchased by the end consumer in retail stores can thus be filled and transported in such bags.
- the opening is closed after the goods have been filled in by folding it over and/or crunching it up one or more times.
- the folded end which previously provided the opening may also be closed securely, for example by using an adhesive such as tape.
- DE 102012 104619 A1 describes such a bag, which includes handle openings in the area of the opening, so that a bag filled with goods can be carried more easily by the user.
- bags with handle holes are not suitable for other applications.
- the bags cannot be filled with goods and can be closed in a simple manner, so that the filling space is closed off from the environment. Therefore, these bags are not suitable for mail order, for example.
- the object of the present invention is therefore to propose a generic bag with handle openings which is suitable for other applications.
- a bag according to the invention which comprises the preamble features of claim 1, is characterized in that the handle opening extends through the second wall outside the fold-over area and through the fold-over area.
- the handle holes are already made in the finished base, so that the bag can be filled particularly easily via the remaining opening, without the handle holes getting in the way during the filling process.
- the handle opening is also used in the following.
- a handle opening according to the invention can be provided at various points in the manufacturing process for the bags. They can The necessary steps for this are carried out when the starting material is a web of material, even before a tube is formed from the web of material, from which the later bags are separated. The handle openings then have to be prepared for an individual bag at two different points, namely on the subsequent cover area and on the subsequent second wall outside of the cover area.
- the handle openings can be made in the later turn-up area and on the second wall outside of the turn-up area after a tube has been separated into tube pieces to form the actual bag.
- the separation takes place in that pieces of tubing are torn off at the front end of the tubing along a previously introduced weakening line, in particular a perforation.
- a piece of tubing is present with a first wall and a second wall, which are connected to one another via side edges, with the second wall protruding beyond the first wall when viewed in the longitudinal direction of the bag.
- no bottom has been formed yet.
- two openings can be introduced, which later lie one above the other after the base has been formed and together represent a handle opening.
- At least one punch can be provided to produce handle openings, with which pieces of material can be separated and removed from the second wall outside the fold-over area and/or out of the fold-over area.
- a punching blade of such a punch can have a circumferential contour. Alternatively, the contour can also be open, so that the pieces of material remain on the bottom, so that the full handle opening only occurs when a user grasps the bag through the handle opening.
- a handle opening prepared in this way, but not yet final, can also be produced by a perforating knife.
- a so generated perforation has the advantage that the pieces of material numerous webs are still connected to the bag, so that, for example, a disturbance caused by pieces of material folding over can be avoided.
- Perforations or punchings can also take place without contact, in particular with the aid of a laser cutting device.
- a device for producing handle openings can be arranged according to the method described above, seen in the direction of production, between an unwinding device for unwinding a material web and a tube forming device.
- such a device can be arranged between the tube forming device and the bottom folding device. It is also possible to provide the device for producing handle openings behind the bottom folding device, viewed in the direction of production.
- first wall and second wall are not to be understood as meaning any directional assignment. This means that the first wall can be arranged, for example, at the top or bottom in the production process.
- a bag according to the invention comprises paper or consists entirely of paper.
- the cover area is connected to the first wall by means of a first connecting surface, the cover area being connected to a part of the side of the second wall facing the filling space with a second connecting surface.
- this part of the side of the second wall facing the filling space is free from the first wall, ie it is not covered by it.
- the connection with the second wall serves to ensure that a filling material located in the filling space cannot get into the environment through the handle openings.
- a connection area is defined by the area within which the aforementioned components, in particular the first wall, the second wall and the fold-over area are connected to one another.
- connection can be created by applying adhesives and then bringing two components into contact.
- An adhesive can be a cold glue, in particular a starch-based glue, a hotmelt, ie an adhesive that can be activated by supplying heat, or double-sided adhesive labels.
- a gluing unit is provided for the application of the adhesive, which, for example, carries a format piece corresponding to the connecting surface, which is in particular elastic, on a rotatable element. Such a format piece is often referred to as a cliché.
- a gluing unit can include a nozzle gluing device. This nozzle gluing device comprises a number of nozzles whose glue flow can be established or interrupted by means of valves. It is a row of nozzles in the transverse direction of the
- Transport direction of the bag is conceivable, with the valves being opened or closed in accordance with the passage of a bag of the desired area. It is also advantageous if the second connecting surface completely encloses the handle opening. In this case, it is preferred if the connecting surface is directly adjacent to the edge of the handle opening. A fully enclosed handle opening avoids that in the eventual bag the two layers of the handle opening formed by the second wall outside the foldover area and by the second wall separate, resulting in a more difficult gripping of the bag by the user can.
- first and the second connecting surface form a common connecting surface, with the fold-over area of the second wall being connected both to the first wall and to the second wall.
- the bag is formed from a flat web, the edges of the flat web being connected to one another along a connecting seam running parallel to the longitudinal direction, the connecting seam being encompassed by the second wall.
- a flat web is folded over at least along two longitudinal edges, with the edges of the web overlapping on the second wall and being connected to one another there.
- a known tube forming device can be provided for this purpose, in which the flat web is folded upwards (with respect to the usual normal direction), which is followed by a turning station.
- the longitudinal seam can, for example, first be associated with the upper side of the tube and, after turning, the lower side, which then represents the second wall in the case of the isolated tube pieces.
- the flat web can be turned over downwards.
- the tube formation is carried out in such a way that the edges of the material web are folded down so that they overlap below the first wall.
- This alternative is suitable as the preferred solution, but should the invention be used for an existing machine, the provision of a turning station is suitable since this can be retrofitted.
- the advantage of this aforementioned procedure is that, in particular due to the action of a cliché for gluing the first wall, the connecting seam is often pulled open again at the edges and edges by adhering to the cliché, so that proper bottom formation is not possible is always achieved. This circumstance is avoided by the aforementioned design of the bag.
- the bag can be formed from a piece of flat web separated from a flat web. It is also conceivable that the
- Envelope area around the handle opening running reinforcement element is arranged.
- a handle element can be reinforced so that the bag can be used safely even with heavier loads and the risk of the handle opening tearing is reduced.
- This reinforcement element which can be designed, for example, as a piece of paper, which in particular comprises paper, is placed on the second wall and/or the cover area and connected before the bottom is closed.
- This step is particularly preferably carried out before a tube is formed from a flat web, since the aforementioned areas are particularly easily accessible here.
- an applicator can be provided, which preferably uses a roller to deposit the reinforcing elements on the aforementioned areas at regular intervals.
- the applicator can include a separating device with which reinforcement elements can be separated from a further web of material.
- the above-mentioned object is also achieved by a method for manufacturing a bag, in particular a bag according to the above description, in which tube pieces are provided or a tube is separated into tube pieces, the tube pieces comprising a first wall and a second wall, which
- the method according to the invention is characterized in that at least one handle opening is introduced, which extends through the second wall outside the fold-over area and through the fold-over area.
- a system for producing a bag in particular a bag and/or for carrying out the method according to the above description, with a device for providing tube pieces or with a device for separating a tube into tube pieces, wherein the tube pieces comprise a first wall and a second wall, which are connected to one another via side edges so that a filling space is provided, with a transport device for transporting the tube pieces in a transport direction, with the second wall protruding beyond the first wall when viewed in the transport direction, with a Bottom-forming device for molding a bottom onto the piece of tubing, wherein a folded-over area of the second wall can be folded over onto at least parts of the first wall along a fold line.
- the system according to the invention is characterized by at least one device for introducing at least one handle opening, which extends through the second wall outside the fold-over area and through the fold-over area.

- FIG. 1 shows a web of material 100 from which several bags according to the invention can be produced or are produced.
- the web section 101 from which the tubular section required for the manufacture of a bag is produced is identified by thick, dot-dash lines 102 which run partially transversely to the transport direction T of the flat web 100 .
- the lines 102 thus represent dividing lines and can be formed by perforation. Some of the lines 102 also have directional components in the direction of the transport direction T, with the result that after the later tearing off of individual tube pieces, the two
- Walls are staggered to each other, which will be explained in more detail in connection with FIG.
- the representation of the flat web is preferably a view of the outer surfaces of the later walls of the bag.
- the web section 101 is divided into the surface area 110, the majority of the later second
- the surface areas 110 and 111 are delimited by the nearest broken lines 103 or by the lines 104 . Their meaning is described below.
- the broken lines 103 and the dash-dotted lines 104 indicate the optional gussets, with the lines 103 forming the outer edges of a gusset and the dash-dotted lines 104 forming the inner edge of a gusset.
- the lines 103 are omitted and the lines 104 form the outer longitudinal edges of the bag.
- the areas 105 and 105' on the longitudinal edges of the flat web 100 form those areas which overlap after the tube formation and adhere to one another, for example by gluing. Grip openings can already be introduced into the material web, which are designed as grip holes in FIG. 1 by way of example.
- two handle openings 109, 109' are provided for each subsequent hose section, so that these two handle openings 109, 109' lie on top of one another after the step of folding over the bottom flap and together form a handle opening.
- the curved arrows 106 and 107 now indicate that a tube is formed from the material web 100 . Lateral folds can also be optionally inserted together with the tube formation, since the formation of all folds that run in the transport direction T is efficient within a single station.
- FIG. 2 now shows a tube piece 200, which is created from the material web shown in Figure 1 through the steps of tube formation and separation, in which by applying a force in direction T to the respective front end of the tube and by holding the tube behind the respective first dividing line 102, the respective front hose piece is torn off along the dividing line 102.
- the areas 105 and 105' are arranged in an overlapping manner and are connected to one another by a connection, in particular by using adhesive. Lines 103 and 104 can also be seen.
- Hidden lines or line areas are represented by broken or dash-dot lines.
- FIG. 3 now shows the hose section 200 in a plan view. The individual features already described in connection with FIGS. 1 and 2 are also present. The subsequent fold line 201 around which the bottom flap 202 is folded can be seen. An adhesive surface 203 was applied in a further step to the piece of tubing, wherein this adhesive surface 203 is applied both to the first wall and to the second wall.
- the adhesive surface 203 has areas angled to the right and left and extends close to the fold edge 201 . This ensures that the bottom flap 202 is connected both to the outside of the first wall 111 and to the inside of the second wall 110 . Furthermore, the area of the second wall in which the handle openings 109 and 109' are arranged is subsequently separated from the interior of the subsequent bag by the connecting surface, so that access to the interior through the handle openings is prevented.
- FIG. 4 now shows the finished bag 300.
- only the bottom flap 202 had to be folded over onto the first wall 111 around the fold line 201 and preferably pressed.
- the contents can now be introduced into the interior in the area of the closure flap.
- the bag can be carried by a user via the handle opening.
- FIG. 5 now shows a variant of a hose section 400 for the fixing of bags according to the invention.
- This hose section is designed similarly to the hose section shown in FIG. Therefore, numerous features are not specified and reference is made to FIG. 3 and the associated description. The differences are discussed below.
- adhesive surface 401 differs from adhesive surface 203 in that its shape deviates from it and is preferably rectangular in shape, so that after folding over, bottom flap 402 in particular is connected to the inside of the second wall and to the outside of the first wall over the entire area as possible , In particular is glued.
- a handle opening 403 is now made in the bottom of the bag, with the handle opening being arranged entirely in the area in which the bottom flap 402 is connected directly to the inside of the second wall 110 . This situation can be seen in FIG.
- the handle opening can also be made before the bottom flap 402 is folded over.
- the introduction of the handle opening after the bottom flap has been folded over can be combined with the embodiments according to FIGS. 1 to 4 and the associated description.
- the adhesive surface can be configured analogously to that shown in FIG.
- the sequence for opening such a bag can be seen from FIGS. 8, 9 and 10.
- the reference symbols have the same meanings as were described in connection with the previous FIGS. 1 to 7.
- FIG. 11 shows the course of a preferred method for manufacturing a bag according to the invention.
- a web of material 100 is first provided.
- the handle openings 109, 109' are introduced into this material web.
- transverse perforations are introduced into the material web, which define the subsequent separating edges 102.
- the transverse perforation and the making of the openings can be arranged in the same station of a device for fastening bags according to the invention.
- a transverse perforation knife and punches for making the openings are arranged together on a rotating element, for example a knife roller.
- step 603 reinforcement sheets are applied, for example by a corresponding application unit in the device.
- the tube is then formed in step 604, in particular with the simultaneous folding in of side folds.
- step 605 the isolating of the hose into pieces of hose.
- step 606 an area of adhesive is applied, and in step 607, the bottom is folded over and secured to the first wall of the bag. This completes the bag. If no handle openings have been made, these handle openings can be made in the finished floor in an optional step 608 . This step 608 can also occur between steps 605 and 606.
- FIG. 12 shows a device 1 for producing bags.
- the device 1 comprises an unwinding device 2 to which the material web 100 is fed in the form of a roll 4 . Starting from this winding 4, the material web 100 is guided by guide rollers 5 of the
- This station 6 can include one or more cross-cutting or cross-perforating knives, not shown in detail, which rotate on a roller 7 .
- Handle openings 109, 109' can be arranged in this station and/or also rotate on the roller 7.
- the material web 100 runs over a counter-pressure roller 8, which primarily has the purpose of providing the counter-pressure necessary for the cutting or perforating process.
- the web is not severed during this cutting or perforating process, but rather the material web 100 can be provided with weakening cuts or perforations 102, along which the tube to be formed later tears into tube pieces for separation.
- the web of material 100 then runs through a nip formed by a further guide roller 5 and a roller designed as longitudinal gluing 26 .
- a tube 10 is formed from the material web 100 by the material web 100 by means Guide elements, such as guide plates, is turned in laterally, so that the edges of the material web then overlap.
- the subsequently overlapping areas have already been provided with a suitable adhesive by means of longitudinal gluing 26 .
- Lateral folds can also be inserted while the paper web is being folded.
- the side folds can also be inserted after the tube has been formed.
- the hose 10 is now usually continued in the transport direction T. After the tube 10 has been produced, it is separated into tube pieces 12 in the tear-off station 11 . For this purpose, the hose 10 is guided through the nip of a first pair of rollers 13 .
- the tube As the tube continues to advance, it enters the nip of a second pair of rollers 14.
- the peripheral speed of the rollers of the second pair of rollers is constantly or at least temporarily greater than that of the rollers of the first pair of rollers 13, the peripheral speed of which advantageously corresponds to the transport speed of the tube 10.
- the second pair of rollers 14 engages the tube 10 . This can be done by the leading end of the hose running into the nip of the second pair of rollers.
- the rollers of the second nip 14 can also be moved relative to the tube 10, for example perpendicularly, and placed against the tube. When the rolls of the second nip 14 engage the tube, the tube tears along the cut or perforation made in the web at station 6.
- One of the rollers of the first pair of rollers 13 can also carry a cutting knife, with which the tube can be separated into individual tube pieces 101 by means of so-called clean cuts.
- the perforation of the flat web within station 6 can be omitted.
- the upper edge of the bag has an attractive edge that is not frayed or frayed, as is the case when pieces of tubing are torn off.
- the hose piece 200 torn from the hose now reaches the base gluing and base folding station 15 .
- the leading end of the hose length is folded over so that parts of the lower (second) wall are folded back together with parts of the upper (first) wall, so that parts of the upper wall and through the openings parts of the lower wall also rest on the upper layer.
- a suitable element for example a rod
- the flap and/or the area of the outside of the upper wall on which the flap rests after it has been folded over is provided with an adhesive, for example with glue.
- the glue application device which is symbolized by the glue cylinder 17 in FIG. 12, is used for this purpose.
- the bottom maker cylinder 16 sets it down on a table 18 .
- the bags are usually arranged in a vertical position. From this table 18 the bags can then be removed in stacks in a suitable manner.
