Embodiment Construction

[0043] In FIG. 1 reference numeral 1 denotes a material web made of a flexible material which can be unrolled from a roll 2, for example. In this case, the material web 1 is folded in its longitudinal direction, forming several superposed layers 3 of which two inner layers in each case are embodied as side gussets. The folded material web 1 is constructed similarly to a tube, the longitudinal sides 5, 6 of the material web 1 being superposed in the lateral region 4.

[0044]FIG. 2 shows a section through the folded material web 1 and is intended to illustrate the structure. FIG. 2 shows the various layers 3 of the folded material web 1, the material web 1 being folded in such a manner that the longitudinal sides 5, 6 and the gusset edges 7, 8, 9 form the lateral edges of the folded material web. FIG. 2 further illustrates that the folded material web 1 has two outer layers 10, 11 and in the lateral regions 4, 12, layers 13, 14 which are located therebetween in each case and are embodi...

Abstract

A method for producing a package made of a flexible material, in which a single flexible material web is folded longitudinally, and superposed layers of the folded material web are firmly bonded to one another. At least one section of the material web is constructed as a tubular piece, and individual gusset edges of the material web are at least partly cut. Tubular pieces of a predetermined length are cut from the material web, in the area of at least one opening of the tubular piece. The outer layers are turned over, and layers of the material located therebetween are shortened. A sealing element is applied to the ends of the shortened layers and brought in contact with one of the outer layers. The shortened ends are closed after re-turning the outer layers, and fixed to a respective outer layer. Predefined regions of superposed layers of the tubular piece are then firmly bonded to one another.

Description

BACKGROUND OF THE INVENTION [0001] The invention relates to method for producing a packaging means made of a flexible material, in particular for producing a side gusset bag made of plastic film. Furthermore, the invention relates to a packaging means made of a flexible material, in particular side gusset bags made of plastic film, comprising a front wall and a rear wall between which side gussets extending over sections of their lateral areas are disposed, said side gussets being designed to be shortened in the upper region of the packaging means, the packaging means having a gusset-free head region between the front and rear wall. [0002] It is known to produce a packaging means made of a flexible material, for example, a side gusset bag made of a plastic film, by arranging two material webs congruently with respect to one another and positioning predefined functional elements between said material webs and optionally bringing into contact with the material webs. Subsequently, pred...
