weldable material in the method according to the invention to find packaging in particular Films made of suitable polyolefins, such as polyethylene or Polypropylene, or composite application, in which Metal foils, especially aluminum foils, for example for Manufacture of aroma-tight packaging can.
suitable polyolefins such as polyethylene or Polypropylene
metal foils especially aluminum foils, for example for Manufacture of aroma-tight packaging can.
Such weldable or heat sealable Materials are common in packaging production Materials.
a first flat material main web 1 in the direction of arrow 2 a device for manufacturing, not shown a packaging made of plastic film or the like Material promoted in the course of the invention Procedure in the form of a gusseted bag or -sackes received.
a second flat main material web 3 is from an upper level to deflection rollers 4 and 5 after funded below in overlap with the main material web 1, whereupon both material webs 2 and 3 together conveyed flat in the direction of conveyance 2 one above the other become.
a third flat web of material 6 is in the direction of Arrow 7 transversely, preferably at right angles to the direction of conveyance 2 promoted to the main material web 1.
the Material web 6 is moved around from a lower conveyor level Deflection rollers 8 and 9 conveyed to an upper conveyor level, which occupies the same level as the main material web 1.
the material web is in this upper conveyor level 6 to a gusseted cord, in the example shown a double-sided fold strand 10 in the form of a Flat hose 6 'with opposite side Folded edges 11 folded.
the along the two Folded edges 11 folded against each other to form flat tube 6 ' Side parts 12 of the material web 6 border in Area of the vertical longitudinal median plane of the flat hose 6 'preferably without overlap and connection to each other.
Double-sided fold strand 10 From the double-sided fold strand 10 are by means of a Cross cutting device consisting of upper and lower tools 13 double-sided fold sections 14 as flat tube sections separated and by suitable funding, which comprise at least one pair of rollers 15, by that the section 14 with fixation of its folded edges 11 runs through, a folding device 16 to and through promoted this.
a folding device 16 Received in the folding device 16 each section 14 at its leading in the conveying direction 7 End by folding tools, not shown a folding in the form of double corner triangles 17, in which the hypotenuses 21 of the right-angled isosceles triangles in parallel mutual Are facing each other.
2 to 5 show the sections 14 in an enlarged view Scale. Your direction of funding is in turn by the Direction arrow 7 indicated. 2 shows section 14 immediately after its disconnection from the flat tube 6 '. At 18 is the overlap and connection free area between the side parts 12 in the form of a longitudinal gap 18 evident.
the leading end 19 is in the folding device 16 at the top 19a and bottom 19b of the section 14 unfolded, as shown in FIG. 3, and folded laterally inwards, as shown in FIG. 4, and around a transverse fold line 20 folded back onto the top 19a.
the distance of the transverse folding line 20 from the leading one End 19 of section 14 is equal to depth t a gusset or half the width of the flat tube 6 ', and the two corner turns occur 17 in the form of right-angled isosceles triangles, whose hypotenuses 21 at the end of the unfolding process parallel to each other and to the longitudinal folding edges 11 of the section 14 run.
sections 14, at which is passed through at least one further pair of rollers 15, are the corner triangles 17 along the height of the respective corner triangle 17 defining Transverse fold line 20 folded back on itself, so that a triangular pocket 17 'open in the conveying direction 7 of each corner triangle 17 is formed, as in particular 5 can be seen.
the section 14 is on the material web 1 placed as a sub-web and if necessary on this its underside 19b along its longitudinal gap 18 containing vertical median longitudinal plane pinned to its position perpendicular to the longitudinal edges of the bottom sheet 1 to be fixed during further transport.
a fourth flat web of material 22 used for bottoming the packaging is used, is from an upper level around deflecting rollers 23 from an upper level to rest on the Lower lane 1 immediately before the point where the sections were posted 14 brought to together with the subway 1 in Arrow direction 2 to be promoted.
the lower web in the example shown according to Fig. 1A on a vertical section, the Flat web 22 folded into a half tube 22 ', the one long side of a folded edge 24 and the other Long side of the folded, connection-free held longitudinal edges 25 of the half hose 22 ' becomes.
the half hose placed on the lower web 1 22 ' is from the triangular pockets 17' of the sections 14 added by the leading open Triangular pockets 17 'when the sections 14 are applied the lower web 1 grasp the half hose 22 ', so that the Folded edge 24 on the inner boundary fold line 20 (Fig. 5) of the triangular pockets 17 '.
a pair of rollers 15 is a further welding device 29 with top and Bottom tool reached, which is across the web composite extends.
the gusset portions 14a and 14b still combined into the double-side gusset section 14, along their longitudinal edges at the top 19a and the underside 19b of section 14 with the respective adjacent areas of the two main material webs 1 and 3 with the formation of parallel weld seams 31 and
the half-tube 22 'seamlessly along the Hypotenuses 21 of the corner triangles 17 in the Triangular pockets 17 'of sections 14 welded to them.
the double-sided fold sections 14 are after their welding with the two main material webs 1 and 3 and the half hose 22 'in the region of the longitudinal gap 18 containing vertical longitudinal median plane, i.e. on too the lower wall or lower side opposite the gap 18 19b, separated and the adjacent side edges assigned to two adjacent packaging means 32.
This separation takes place during the further transport of the Compound web in conveying direction 2 by means of a cross cutting device 33, which is also the half hose 22 ' between the hypotenuse edges 21 in the gap 18 containing separates the vertical longitudinal median plane. While this separation process also becomes the edge welds 31 in parallel edge welds 34 on adjacent packaging 32 divided lengthways.
Processes are performed by the double-sided fold strand 10 again the double side fold sections 14 separated and in the form shown in Fig. 2, i.e. without folding of corner triangles 17 on the leading End, the main material web 1 fed as a sub-web is in turn promoted in the direction of arrow 2.
the sections 14, which in turn are in Direction of arrow 7 across or perpendicular to the conveying direction 2 are fed, as are the sections 14 of the first embodiment, in the desired width of the packaging 32 corresponding distances to the Lower web 1 placed and pinned to this.
the Main material web 3 is the upper web from an upper Level over the deflection rollers 4 and 5 with the lower web 1 merged and in turn to the already at the Lower web 2 sections 14 attached.
the sections 14 are attached to the two main material webs 1, 3 is in the area of the longitudinal gap 18 vertical longitudinal median plane of the sections 14 by welding or preferably hot melt or the like. Glue orders made.
