Definitions
- the invention relates to a method for producing floor bags with glued inner bar.
- bottom bags for example block bottom or cross bottom bags
- Paper, plastic film or the like form the bottom flaps on the inside the bag unwanted voids such as crevices or pockets, in to which powdery, granular or pasty remnants of the contents of the bag stick can.
- glue a so-called inner bolt, which is usually by a rectangular sheet is formed from the bag material and all around with the Bottom flaps are glued or welded so that the cavities face each other sealed inside the bag.
- a method for producing such bags is known from WO 95/02544, where the bag material as well as the inner bar made of polyethylene on the inside coated paper. After this procedure, the inner bolt on the edges parallel to the narrow edges of the Run the floor, glued to the associated floor tabs, and parallel towards the broad edges of the floor face each other coated surfaces of the inner transom and the bottom flaps through continuous Weld lines welded together.
- the usual method for the production of floor bags is that the Starting material in the form of an endless web drawn off a roll and then it is first closed to form a tube, which is then cut into suitable lengths is divided to form the individual bags.
- the so obtained Pieces of tubing are continuously rotating on a rotating drum fed, at which a winding station successively in the circumferential direction, a floor laying station and a closing station are arranged. In the winding station the top and bottom layers are initially flat on top of each other the hose at the bottom end pulled apart so that a wide open floor opening.
- this inner bolt must between the winding station and the floor laying station in the floor opening introduced and then welded or glued to the bottom tabs become.
- the structure of the device is considerably complicated, and since the additional Process steps such as applying the adhesive, making the weld lines and the like take a certain amount of time, the total processing time increases, so that in the continuous manufacturing process only a correspondingly low output of bags can be achieved.
- DE-A-25 14 219 describes a method for producing cross-bottom bags known in which for gluing the bottom flaps only on self-adhesive Contact adhesive is used even before the hose is closed is applied to the continuous material. If there is an internal latch in the floor with such a method, there is the problem, however, that the adhesive surfaces provided on the hose for the inner bolt already can glue together prematurely when the hose through the device is transported.
- the object of the invention is therefore to provide a method which with a relatively simple system a more rational continuous Manufacture of bags with glued inner bar permitted.
- the method according to the invention has the advantage that the for gluing the The interior bolt required the adhesive before the hose was closed on the Starting material for the bag can be applied. Because the contact adhesive is not liable unless two surfaces are coated with this contact adhesive can be pressed against each other, unwanted adhesions in the Closing the starting material to a tube and the following Avoid editing. Only after the inner bolt has been put on the corresponding one The adhesive surface is in turn provided with contact adhesive, the Contact adhesive take effect. The inner bars can also be opened before they are fed to the floor-laying drum coated with contact adhesive so that immediately no additional time for the application of the Glue is needed in hard-to-reach places and on the circumference of the floor laying drum also no corresponding order facilities provided will need.
- the adhesive surfaces coated with contact adhesive on the upper and lower Material layer of the hose are arranged offset against each other, so that they do not immediately after closing and laying the hose come into contact with each other. Therefore, the means of transport can attack the hose without causing premature sticking of the the contact adhesive coated areas.
- a block bottom bag 10 for example consists of paper and inside with plastic (e.g. polyethylene) is coated.
- the bag has an upper wall 12 and a lower wall 14, which are connected to one another by gussets 16, and a base 18 with a rectangular plan, still in the state shown is not closed.
- the bottom 18 is made by four in one piece with the Main part of the bag formed bottom flaps, namely two of protruding trapezoidal tabs on the top and bottom walls of the bag 20 and two rectangular flaps lying in the extension of the side folds 16 22.
- the trapezoidal straps 20 and the rectangular straps 22 hang over Triangle turns 24 together, which are folded back onto the trapezoidal flaps 20 are.
- the bottom has an inner bar 26 which is separated by a separate one Sheet is made of paper and also coated on the inside with polyethylene is.
- This inner bar 26 is on its longitudinal edges 28 with the Glued inner surfaces of the rectangular tabs 22 and the triangular folds 24 and is also on its narrow sides with the top in Figure 1 facing surfaces of the trapezoidal straps 20 glued.
- the trapezoidal tabs 20 are known Folded over inside and glued together.
- Figure 2 shows the square blank in plan for the inner bar 26.
- the area of the blank which is visible in FIG. 2 is that which is laminated with polyethylene Inner surface, which points downwards in FIG. 1.
- the cut has side flaps 30, which are later folded back so that the corresponding fold lines form the longitudinal edges 28 of the inner bar.
- On the flaps 30 is a glue or hot melt adhesive in the form of adhesive lines 32 applied.
- adhesive lines 32 With these adhesive lines 32 the folded over Flaps 30 of the inner bolt with the rectangular tabs 22 and the triangular folds 24 glued in Figure 1.
- Two further adhesive lines 34 run according to Figure 2 parallel to the other two edges of the blank. This Adhesive lines 34 are formed by contact adhesive and are used for gluing of the inner bolt with the trapezoidal flaps 20 and - in the area of the flaps 30 - with the triangular turns 24.
- FIG 3 is the bottom area of a blank for the actual bag 10 shown.
- the visible side of the cut corresponds to the laminated one Inside of the bag.
- the cut is by longitudinal Fold lines 36 divided into several fields, according to the finished bag Figure 1 form the upper wall 12, the lower wall 14 and the side gussets 16.
- these fold lines 36 on the right edge of the blank in Figure 3 a fin 38 and an adhesive tab 40 formed with an adhesive line 42 made of glue or hot-melt adhesive is provided.
- the fin 38 and the adhesive tab 40 are on the associated fold lines 36, respectively folded over in opposite directions by 180 °, and the glue tab is then glued to the left edge of the wall 14 in Figure 3, so that the Cut to form a so-called fin seam to form a tube is closed.
- the use of a fin seam has the advantage that the Glue tab 40 with its side coated with polyethylene on the same coated side of the wall 14 comes to rest, so that the bag inside is completely lined with polyethylene and the paper through which Moisture could penetrate due to wicking, none Has connection to the inside of the bag.
- the trapezoidal straps 20 and the rectangular straps 22 are formed by the main part of the bag separated by a transverse fold line 44.
- transverse fold line 46 is provided which allows the bottom 18 in the manner shown in Figure 1 in the plane of the upper and lower walls 12, 14 to move.
- this fold line 46 is only shown in dashed lines because the material there in the state shown in Figure 1 is not folded.
- the longitudinal fold lines are corresponding 36 in the area of the rectangular tabs 22 only shown in broken lines. Here the material is only temporarily folded when the hose is made, and the folds will be undone later.
- Diagonal folding lines 48 separate the triangular folds 24 from the trapezoidal flaps 20 and also form in the area of the side folds 16 further triangular folds that allow the gussets in the figure 1 shown to connect to the rectangular bottom 18.
- the trapezoidal plate 20 lying in the extension of the upper wall 12 and the Adjacent triangular turns 24 are with a U-shaped adhesive line 50 provided, which is formed by contact adhesive and the counterpart to one the adhesive lines 34 of the inner bar 26 forms.
- the other trapezoidal tab 20 as well as the fin 38 and the adhesive tab 40 provided with L-shaped adhesive lines 52, 54 made of contact adhesive, which together form the counterpart to the other adhesive line 34 of the inner bar 26.
- the bag 10 is placed in together with a plurality of similar bags a continuous process in the following manner.
- the starting material that forms the blanks for the bags 10 is called Continuous web pulled off a roll.
- the outside made of paper the web can be printed with a label or other imprint be.
- the adhesive lines 50, 52 and consisting of contact adhesive 54 can already be printed on the web pulled off the roll, since the contact adhesive is only liable if it is also against a contact adhesive coated surface is pressed. Comes in the web wrap the contact adhesive but only with the non-adhesive paper side of the next web position in contact.
- the contact adhesive in the desired pattern on the one withdrawn from the roll Printed web or applied in any other way and the web runs through possibly a drying station.
- the web then passes through a gluing station in which the adhesive line 42 is applied from hot melt adhesive.
- the web is then folded along the fold lines 36 and into one Tube glued.
- the adhesive lines 50 and 52, 54 then come immediately However, lying on top of one another does not adhere to one another as long as there is no pressure on them it is exercised.
- Transport roller for the further transport of the hose attack near the longitudinal edges on the hose where the each other opposite sections of the adhesive lines 50 and 52, 54 by the intermediate Gussets 16 are separated. Hence effect these transport rollers also do not give premature adhesion to the contact adhesive.
- the continuously transported hose is then in a punching or Cutting device cut into tube pieces to form the individual bags, and fold lines 44, 46, 48 are used as necessary pre-grooved by pre-grooving tools.
- the pieces of hose are successively on the peripheral surface of the floor laying drum stretched and run on the floor laying drum at a winding station past where the leading, bottom-side hose end is pulled up becomes.
- the rectangular tabs 22 and the trapezoidal tabs 20 then form together with the triangular turns 24 an approximately box-shaped Bottom opening, as shown in Figure 4.
- the roll material for the inner bars is made from another roll 26 peeled off, provided with the adhesive lines 34 made of contact adhesive and then dried if necessary and then cut to length. Subsequently the flaps 30 are folded over, and the folded over flaps are provided with the adhesive lines 32 made of glue or hot melt adhesive.
- the trapezoidal flaps 20 are then flipped over in a closing station and glued. If necessary, the finished floor is then again with a Pressure roller rolled on. Optionally, rolling can only be done in this Stage take place, so that the rolling between the floor laying station and the closing station can be omitted.
- the adhesive lines 32 of the inner bar become more normal Glue used because these lines of glue are only on the top of the inner bar are in Fig. 3 so that the adhesive can be applied easily can be smeared without the bottom flaps.
- 32 contact adhesives can also be used for these adhesive lines then interacts with corresponding adhesive lines on the rectangular tabs 22.
