In the production of packaging containers made of paper, cardboard., Urten or similar. int a sol- ehe @ EinspanneWohnehin not possible and en is aueh practically not possible at all, the errorderliohen pressure, with which the edge must be pressed against the surface, to raise "because the Zuechnittell in question is then yes Gotort was bent. The Ublichenyelne vei-jendel% -Oen adhesives or seals- Maseen dry or cool in the (lerigen too slowly and The waxes used earlier do not adhere well enough to produce a sufficient bond between the parts on such a small area as is available in such a process *. Surprisingly, however, the hot melt adhesives, despite their similarity to waxes, remain water vapor and third party radioactive even under the usual stresses. This was not to be expected in itself, since the Bohmelz glue, as already explained, otherwise behaved like the known glues used in the packaging industry and was only applied accordingly.

The application of the hot-melt adhesive to one edge of a cut piece It's very easy, because the corresponding edge is then only into one with liquid hotmelt glue filled container needs to be immersed. The order ka =. but of course can also be done in any other way.

The application on a surface can be done in normal wine, for example by means of a stamp. However, the hotmelt adhesive can also be applied by means of a heated tool, for example in accordance with application B 84 164 X / 39a2d by the same applicant. Was finally a Schmelzklebertaden came to the surface placed in all cases been followed so that the respective other Zuaohnitteil is applied immediately * I then to use if necessary hot-melt adhesive with a lower setting-.geschwindigkeit long as the hot melt adhesive still haftMig lat recommends. U.

With hot melt adhesives with a high setting speed, however, you can also make an order first and then later the glue sticker again heat "which can either happen" that the second blank part heats is or that so is working with radiation or the like.

A particular advantage of the method according to the Windun is that no Druckanwandung is required and practically requires no setting time. Immediately after the two cut points are brought into contact, a setting takes place and the xleb seam has the necessary strength in the shortest possible time. so that further processing can take place. In many cases it is twice as long that there is only a small amount of hot melt adhesive on the inside or on the outside of the packaging The cut edge is made or this additional cut edge is brought into contact with the hot melt adhesive on one surface on the side.

Another possibility "which has a vague effect" is that the application is placed in the right angle of a corresponding tab attached to the blank. Nan also proceeded according to the binding so that the blank after it was connected to the blank edge a flap is bent open at right angles in the direction of the cutting edge.

In order to achieve the greatest possible initial adhesion area between the cutting edge and the cutting surface "they came" that are brought to the surface two provided each other at a distance Schmelzkleberautträge = proceed by /. The cutting edge is then brought miaobaU these two tracks and it is then something more hot-melt adhesive material is available for the connection than when using a single bead of hot-melt adhesive. The same came be achieved in that at the The cut edge of the melt adhesive application reinforced on the side "v" is attached, for example, by "toe" can "that laterally vori der.Kante two Sohmelskloberraupen be applied. A corresponding effect was, however, generally achieved Invention achieve that the blank edge before is bent over the hot melt adhesive application and the cutting then edge with the correspondingly widened bow brought into contact with the hot melt adhesive. Serve latter AusfUhrungeform the muddled after Invention is particularly suitable for the case that dead cut parts are used "so b * Umielo» Iee kiln totoff or aluminum channeled, size mm paper " Cardboard or similar U Is there = advantageous according to the bond " that the shaded sides of the accessory parts over the Hot melt adhesive in connection with one another.

It can be applied to the corresponding cut edges or edges of the hoses or container points by simply dipping or bringing a stamp into contact, since these countries generally lie in one plane. The closure plate can consist of a correspondingly punched simple accessory means.

According to a further Kerkmal the invention is characterized in "that a peeled from the roll blank Toll will provide at its edges with the Schmelykleberauftrag. Such Zuaohnittell can then be easily processed into a tube.

According to the invention, a packaging can also be produced in a very simple way by bringing a U-shape bent over at its edges with a melted ball, which is bent in a U-shape to form a rectangular packaging wall.

Gloloher-Weiau is used in both mills In the middle the presentation of Vill. 1 shown Connection between cuts 1 and 2 reached # the Schmelakleber 5 the Zuaohnittkante on both Surrounding sides. If you only want a hot melt adhesive application on one side, you can attach the bead 6 to the side of the cut edge. But you can also bring the edge of the blanks 1 laterally with the bead 7 of the blanks 2 in contact. In both cases, the one-sided hot-melt adhesive application 8 shown in the middle illustration of FIG. 2 is obtained.

Fig. 3 shows a bent at right angles Lasohe 9 the blanks 2, wherein the angling can take place before or after the connection with the blank 1. Also in this case the vonentlichen a one-sided form of adhesive is lo present, but is also passed on the other side by the flap a AbstlItzung overall.

Also in the dargentellten in Fig. 4 type of connection is used a reinforced Schwelzkleberauttrag "namely grazing two beads 11 and 12 applied to the blank 2 and the edge of the blanks 1 is introduced zwiaohen these two caterpillars. Anliches can mm reached by DA 5, the blank 1 at the lower end is provided laterally with two caterpillars 1.3 "14" which, after connecting the two Zu4ohnitte to each other, also result in strong hot melt adhesive applications on both sides.

Instead of increasing the amount of hot-melt adhesive applied, the contact area between the two cut-outs was also increased by bending the cut edge. Thus, the area of the blank 17 connected to the blank 15 via the hotmelt adhesive layer 16 is correspondingly enlarged by slightly bending the edge 18 (FIG. 6). As shown in FIG. 7 , the edge 19 of a blank 20 can also be formed into a bulge, which in any case ensures a secure support. 9 shows the convenient production of such tdUlete and the convenient production of a hot melt adhesive application 21 at the points 22 »93b marked with arrows. Corresponding blanks can be produced continuously.

zYou using beachichteter blanks 24 .. 25, it is recommended that the blanks 26 24 turn the cutting edge in such a manner. that the coatings 27 " 28 have been connected via the hot-melt adhesive layer 3o. In this case, the edge 26 is bent outwards and the hot-melt adhesive layer is attached to the side in such a way that it can no longer be disrupted.

Fig. Lo shows a trim 31, which can optionally also be provided with bent edges, but is in any case continuously provided with a hot melt adhesive application on both sides. After cutting, this blank is bent in a U-shape, as shown in FIG. 11 , with hot-melt adhesive also being applied to the fastener edges. He is then weiteren'Zuschnitt with a * 32, which is manufactured in accordance with "but autweist any form of adhesive" -to the Verpackungabehälter shown in FIG. 12 connected Fig. 12 shows that the edges of the Zuschnitt43 31 hinausragen4 the blanks 32 something Uber those ko dead has been proceeded roughly in accordance with Fig. 1. However, you can of course also proceed in accordance with Fig. 2 and essentially close the edges of the two blanks to be connected with one another.

In the case of the packaging container according to FIG. 12, the narrower blank is provided with the hot melt adhesive application. But you can also provide the wider cut part with the hot melt adhesive application according to Fig. 1.3. ? lg. 13-Meigt In addition, that one can also proceed in this case according to FIG. 3 , since the edges of the blank 33 are cut so that they, as? Lg. 14 shows that blank 34 can be unfolded onto it. They are then held in this position by the application of hot-melt adhesive previously located on the edges of the blanks 34.

FIG., 15 shows that mm or to the * ends of the U-shaped folded blanks more tabs 359 36 & 379, can mount 38 which may serve the container to Versteltung, but also in all of the L "heights"v> 6? 16 finally shows a container base 37, which can be made in conventional wines and is provided on its edge with a smear adhesive "which can have been made, for example, by stamping or dipping the De-Ulterrandes. A lid 38, which consisted of a simple rectangular accessory without any adhesive, was placed on this undercover.

The application of the hot melt adhesive has already been mentioned. If immediately after application of the Sohmelzklebers establish a connection with the other home part is to take place, so it is important "that $ not only the Necessary to keep the hot melt adhesives flowing. Warmth- amount "but also an additional @ amount of heat for the speaking Aufheinung the Zusohnitteeilepaut that of the Sohnelakleber is applied "to the end of what in particular this can cause "a heated"' Tool is used.

It is not uncommon for the Kunntet order is necessary " that an order fin the form of a hanging caterpillar or the like. he follows. Thus, rather a AUOH -punktweiner order, because when in contact with the another cut or when reheating later the individual points * then flow together to form a caterpillar.
