Definitions
- the invention relates to a method for producing gusseted bags from a flat lying plastic tubular film section.
- Gusseted bags made of plastic such as polyolefinic films such as PE and PP are thereby made from flat-lying plastic tubular film sections manufactured that this at one end with a covering all layers transverse weld seam are provided. Because of the usual high weight of the filling material and the resulting load for the sacks are usually made from particularly thick plastic films.
- the tube sections can be made of such thick plastic films Only attach floors with cross welds, long for their execution Welding times are required. When welding, it is necessary to heat through all foil layers, in the area of the side gussets through four foil layers, to pass through to ensure the necessary melting and welding. Because of this heat conduction process, which increases with the film thickness and the number of layers increases, the welding time is considerably longer, so that the bags can only be produced with low output.
- the object of the invention is therefore to provide a method of the type mentioned propose after which side gusset bags made of plastic film with larger Have the speed established.
- this object is achieved in that one end of the plastic tubular film section in the way with a staggered cut or a staggered tear along a perforation is provided that in plan view on the graduation the rear wall protrudes from the front wall, and that the graduation to the area of a fold line, which is in the area of the cut edge the front wall is located, provided with an adhesive application and the staggering is folded around the folded edge on the front wall.
- a method for Production of gusseted bags from paper is already known.
- the invention is based on the surprising knowledge and measure, this in the production processes known from paper sacks for the production of plastic sacks to transfer, where the floors were previously formed by welds were.
- the gluing can be improved by further subdivision of the grading.
- the rear wall protrudes from the top view of the graduation Gussets and the gussets protrude from the front wall.
- the staggering can also cover the gussets in such a way that the lower ones Layers of the gussets protrude from the upper layers.
- FIG. 1 is one of a flat-lying plastic tubular film web provided with gussets Plastic tubular film section torn off along a perforation line 1 can be seen, the plastic tubular film web in the Way was provided with a graduated perforation line that the staggering shown in FIG. 1 results.
- the staggering of the layers at the end of the tubular film section at which the bottom is to be formed is designed in such a way that a top view of the Tubular film section 1, the rear wall 2, the side folds 3, while the gussets the front wall provided with a corresponding free cut 4 tower.
- the staggered layers 2, 3 with a suitable adhesive application and the graduation is then around the line 5 folded and pressed against the front wall 4, so that the from Fig. 2nd apparent glued floor results.
- the upper layer of the Side gussets with a staggered cut along the dashed lines in Fig. 1 is.
