Definitions
- the invention relates to a large bag with an outer bag consisting of a tube piece with double-layer walls made of film or fabric material of high strength and an inserted inner bag, in which the lower end of the tube piece is pulled together to form the bottom of the bag and held together with a rope and the upper edge through the folding or deflecting edge connecting the inner and outer sack walls is formed, which is interrupted by at least two longitudinal incisions or cutouts, and in which at least one supporting cable pulling together the opening edge is drawn into the wall loops opened by the incisions.
- the tube piece forming the outer bag with double-layered walls is produced in that an edge of a tube piece is drawn inwards and thereby the tube section is turned over so far that the inwards drawn in half of the tube section forms the inner wall of the outer bag.
- the seamless upper edge of the tube piece is then provided on opposite sides with longitudinal cuts, so that two wall loops consisting of the inner and outer walls are formed, into which a rope ring is then inserted, which forms a carrying loop, which is used for lifting and transporting the bag can be hooked into a crane hook.
- this known large sack has the disadvantage that it has to be manufactured essentially by hand, because there are no machines available which can produce tubing sections with the inner wall of the sack from the tube sections with reasonable effort.
- the object of the invention is therefore to provide a large sack of the type specified at the outset, which can be machine-made essentially without manual labor.
- the tube piece consists of a tube or half-tube section, the opposite cut edges of which are connected to one another by a seam.
- the carrying outer bag of the large bag according to the invention can therefore be produced in a simple manner and also mechanically with uncomplicated devices in that one half of a tube section is placed on the other and the cut edges of the tube section lying on top of one another are sewn to one another or otherwise connected to form the tube piece.
- the tube piece forming the outer bag instead of folding a tube section and connecting its cut edges to one another, it is also possible for the tube piece forming the outer bag to consist of two tube or half-tube sections which are connected to one another at their cut edges by seams.
- the bottom-side fold edge is provided on both sides of the sewing seam or the sewing seams with incisions from which the knotted ends of the rope pulling the bottom are led out.
- This configuration enables a particularly firm construction of the bottom, because there are no seams forming the bottom and it is not necessary to wrap free-flowing sack walls with ropes and to knot them to form the bottom, as is provided in the large bags mentioned in the prior art.
- the bottoms form special weak points, which are avoided in the sack according to the invention in that the hose sections forming the sack hose piece are arranged in a ring circumferentially.
- a reinforcing bottom sheet can be placed on the contracted bottom area.
- the tube section forming the outer bag expediently consists of a round fabric tube made of stretched plastic tapes.
- the inner bag can consist of a conventional bag made of plastic film.
- a method for producing the large sack according to the invention is characterized according to the invention in that a flat-lying tube or half-tube section is provided with two incisions on the upper fold edge which later forms the filling side, adhesive swabs or strips are applied to one side of the section and to half of these
- the flat-lying inner bag is placed on the side at a distance from the later side edges of the bag, so that the other half is struck congruently on the inner bag on the first half and the overlapping edges of the section are connected to one another by a sewing seam and that in the through the upper and lower folded edges of the section formed wall loops with their ends outwardly protruding ropes are inserted or previously inserted.
- the side edges of the flat lying In Nensackes are expediently folded in so that when the inner sack is filled it can expand without tension and can rest against the inner walls of the carrying outer sack.
- a piece of hose 1 consisting of plastic ribbon fabric is transported in the direction of arrow A in FIG. 1a.
- two incisions 2, 3 are made, which cut through the edge and both layers lying one on top of the other and are at a distance from one another which corresponds to approximately half the length of the hose section.
- the slots or incisions 2, 3 can also assume a different position from one another and can also be made at a different time.
- glue dabs 4 and 5 are attached on the side of the hose section 1 facing the viewer.
- glue swabs can also be provided and the glue swabs do not need to be attached in a row.
- the inner bag 6 is then fed in the direction of arrow B, i.e. transversely to the running direction of the tubular piece 1, and after the edges 8 and 9 of the tubular inner bag ( 6) have been folded around a shoe 7, placed on the tube piece 1.
- the hose section 1 is then, as can be seen from FIG. 1, folded onto itself.
- a film bag with side folds can also be inserted. It is only important that the inner bag 6 is so narrow that the side seam 10 (for example sewing seam) connecting the cut edges of the tubular piece 1 can be formed unhindered, and on the other hand the inner bag can be placed against the side walls of the carrying outer bag without tension during filling.
- side seam 10 for example sewing seam
- a double-layered tube piece with upper and lower seamless seams and a single side seam 10 is then formed from the tube piece 1, in which the inner bag 6 is fixed via the rows of glue dabs 4 and 5.
- the superimposed cut edges of the tube piece 1 are folded together and the side seam 10 is carried out by the folded edge.
- the sack bottom can only be pulled together and knotting the two sack ends together.
- a rope is then also inserted into the upper hem, the ends of which are knotted together in the area of one of the two slots or incisions 2 or 3.
- the cable parts visible in the area of the two slots or incisions 2 and 3 are then combined by means of a clip 13, so that, as shown in FIG. 2, only a single eyelet is formed which can be easily gripped by the crane hook.
- Fig. 2 shows the sack produced by the method described with a side seam 10 and the lower hem 11, which is gathered together by a rope 14 and thereby a bottom was formed.
- the two slits or incisions 2 and 3 and the hem 12 gathered by the supporting rope 15 can be seen.
- the filling end of the inner bag 6 is tied together at the upper edge 16 after filling, as shown in FIG. 2.
- Fig. 3 shows that the upper edge 16 is pulled out of the supporting outer tube before filling from one of the slots or incisions 2 or 3, so that a filling nozzle can be inserted.
- the entire bag hangs on a crane hook during the filling process.
- the fixation of the inner bag 6 via the rows of glue points or rows of glue spots 4 and 5 can, if necessary, be designed so weakly that the fixation points can be released without material destruction.
- the fixation points ha ben merely the task of ensuring that the inner film tube can be pulled open when the carrying outer bag is opened, without it being necessary to inflate the inner bag by means of air.
- FIG. 4 shows the bottom area of a sack according to FIG. 2 in a perspective view
- FIG. 5 shows the bottom area of a sack which is produced by a method other than that described for FIG. 1, namely the modified method
- a longer piece of hose 1 which is folded onto itself
- two smaller pieces of hose are placed on top of one another in such a way that upper and lower seamless seams and then two side seams 10 'and 10 "are formed instead.
- the bag described above is characterized by a particular strength because the carrying outer bag is double-layered, in such a way that an upper and a lower seamless seam is formed, rope rings are inserted into the two seams through which they gather together to let. The gathering takes place in the bottom area before filling and in the area of the filling end when the sack is lifted over the rope ring by means of a crane.
- the inserted inner bag 6 can be welded or tied at the bottom. Furthermore, the bottom end of the inner bag 6 can be folded over so that it can expand freely during filling.
- a cover sheet can be placed on this opening.
- the cover sheet can already be placed on the tube piece 1 before the tube piece 1 is folded over and before the inner bag 6 is placed on it and, if necessary, also connected to it.
