Problems solved by technology

But the disadvantage of this solution is that such welds are hard and brittle
This can lead to cracking of the weld seam under impact loads and thus also product leakage

Embodiment Construction

[0054] exist figure 1 The packaging machine 30 shown in schematic cross-section in FIG. 2 is used to fill open-mouth bags 1 with product 8 . Such a product can be, for example, a bulk material with granules 44 shown schematically above the product feed 54 . However, it is also possible to pour other products 8 into the bag 1 , for example liquid or pasty products.

[0055] The packaging machine 30 is in the form of an FFS packaging machine and has a storage film 31 comprising a tubular roll. In the storage film 31 there is a coiled tubular film 32 which is used for the manufacture of the bag 1 . By providing the storage film 31 with one or more tubular rolls, the open-mouth bag 1 can be manufactured as desired. Furthermore, in particular the individual bag lengths can be varied flexibly and easily adapted to the filling volume required each time.

[0056] The tubular film 32 unrolled from the film roll of the storage film 31 enters the packaging machine 30 through the film...

Abstract

Packaging machine and method for filling products into open-mouth bags with side creases and such open-mouth bags. The packaging machine includes a filling mechanism for filling open-mouth bags from a filling end. A closure is provided, by means of which the filling end can be completely sealed in the transverse direction by a weld seam after the filling process. With additional welding mechanism. The additional welding means are suitable and designed to introduce two additional holding seams in the side folds of the open-mouth bag, laterally spaced apart from one another in the transverse direction and oriented approximately parallel to the welding seam.

Description

technical field [0001] The invention relates to a packaging machine and a method for filling open-mouth bags with side creases, and also to open-mouth bags. Background technique [0002] Such packaging machines are supplied with prefabricated open-mouth bags with side creases, or the bag-making takes place in the packaging machine itself or in a device preceding it or belonging to it. Furthermore, for the manufacture of the open-mouth bag, before the open-mouth bag is filled via the still open upper filling end, in particular the tubular material is unrolled from the tubular roll and sections of this tubular material are cut to a predetermined length and Features bottom seam. After the filling process, the filling end is hermetically closed. Packaging machines that form, fill and then close open-mouth bags in the machine itself are also known as form-fill-seal packaging machines (FFS packaging machines). [0003] Tubular membranes are often made from the same plastic mate...
