つ詰込み材料は下向きに前記チューブ内へ延びた詰込み
器パイプを介して詰込まれる。In the manufacture of known types of packages, a web of laminated material stored in the form of a roll is rolled into a tube shape during a downward movement through a packaging machine, after which the overlapping edge bands of said web are folded together. It is sealed and stuffing material is stuffed through a stuffing pipe that extends downwardly into the tube.

引続いての下向きの運動中に、詰込み材料を詰込まれた
チューブは密封用顎金の助力により横断方向に密封され
る。During the subsequent downward movement, the tube stuffed with stuffing material is sealed transversely with the aid of the sealing jaws.

上記密封用顎金は熱の供給と同時に、上記チューブ壁を
互いに押圧して、なお連結されている個々のパッケッジ
の相互間に液体を透過しないジヨイントを生成する。The sealing jaws simultaneously apply heat and press the tube walls together to create a liquid-tight joint between the individual packages that are still connected.

の完成されたパツケツジに分割される。After possible further forming processes, the sealed tube is divided into individual finished packages by cutting through the transverse sealing zone.

チューブ状への前記材料のウェブの巻き込みで形成され
た長手方向の継目はウェブの一方の端縁が該チューブの
内側に位置決めされることを意味するラップジヨイント
の形を有している。The longitudinal seam formed by rolling the web of material into a tube has the shape of a lap joint, meaning that one edge of the web is positioned inside the tube.

上記積層体の多孔性ベース層が端縁で露出されているの
で、防止手段が構せられなげれば、詰込んだ材料が前記
ベース層内へ吸上げられるであろう。Since the porous base layer of the laminate is exposed at the edges, the packed material will wick into the base layer unless preventive means are provided.

リップの助力で露出された切断端縁を被覆することで上
記の問題が解決されて来た。Up to now, the above problem has been solved by covering the exposed cut edge with the help of a loose plastic strip applied on the inside of the tube over the seam immediately after the formation of the seam. Ta.

このゆるいプラスチックストリップが前記ベース層内へ
の液状内容物の浸透を十分に防止するがこのプラスチッ
クストリップの配置はこのパツケツジの製造中に好まし
からぬ余分の作動段階を伴うことが判明した。Although this loose plastic strip sufficiently prevents the penetration of liquid contents into the base layer, it has been found that the placement of this plastic strip involves an undesirable extra operating step during the manufacture of the package.

さらにその上に故障のおそれを増大するストリップ配置
装置および各種のその他の要素を必要ならしめている。Moreover, it requires a strip placement device and various other elements which increase the risk of failure.

せることを含んでいる。One way to solve this problem of loose strips is to provide the web of said material with a so-called rigid strip, which is already associated with the production of laminate materials to be used in packaging machines, i.e. one of the laminates. extending a layer of coating material beyond the base layer at one edge of the laminate web.

積層機械で製造された積層ウェブは包装機内で使用され
るべき材料ウェブより数倍の幅を有しているので、初め
のウェブはウェブを使用する包装機に適した幅を有する
多数の狭いウェブに分割されねばならない。Since the laminated web produced on the laminating machine has a width several times that of the material web to be used in the packaging machine, the initial web consists of a number of narrow webs with a width suitable for the packaging machine that uses the web. must be divided into

したがって、初めの幅の広い積層ウェブを幅の狭いウェ

上記の問題を排除することと、積層ウェブに堅固な端縁
ストリップを提供するための方法で、簡単且つ経済的で
ありまた幅の狭いウェブへの原材料の所要の分割と同時
に実施されることのできる方法を明確ならしめることが
本発明の一目的である。Eliminating the above problems and providing a rigid edge strip for laminated webs, the method is simple, economical and can be carried out simultaneously with the required division of the raw material into narrow webs. It is an object of the present invention to clarify how this can be done.

行に延在するであろう。The cutting devices 7, 8 both extend reliably through the entire thickness of the material, but the fact that these cutting devices are displaced with respect to each other by a distance a ensures that they are provided on both the front and back sides of the material web. The incisions made will not reach each other, but will extend parallel to each other.

あるいは、より精密には、上方のナイフ７は被覆材料の
上方の層２を完全に貫通して延びた切口を生成するであ
ろう。Or, more precisely, the upper knife 7 would produce a cut extending completely through the upper layer 2 of the coating material.

材料の層２が完全に貫通切断されることを確実ならしめ
るため、上記切口はベース層１内へさらにわずかに延び
ている。To ensure that the layer 2 of material is completely cut through, the cut extends slightly further into the base layer 1.

下方の切断装置８は、被覆材料の下方の層３を完全に貫
通して延び且つさらにその上にベース層１をほとんど完
全に貫通した切断を同様に行う。The lower cutting device 8 likewise makes a cut extending completely through the lower layer 3 of the coating material and above it almost completely through the base layer 1.

下方の切断装置８が被覆材料の層２の下面を害わないこ
とを確実にするため、切断装置８はベース層１を完全に
貫通切断しないようにセットされる。To ensure that the lower cutting device 8 does not damage the underside of the layer 2 of coating material, the cutting device 8 is set so as not to cut completely through the base layer 1 .

ス層１をほとんど完全に貫通している。Therefore, when the method according to the invention for dividing a web of laminated material into a number of separate webs is carried out, parallel to each other each located on the front and back sides of said material and laterally displaced with respect to each other, Two cuts are made for each parting location, one cut cutting completely through the layer 2 of coating material positioned on the top surface of the material, and the other cut cutting completely through the layer 2 of coating material positioned on the top surface of the material. It cuts completely through the layer of coating material positioned on the underside of the base layer 1 and almost completely through the base layer 1.

したがって、この切断作動で、前記積層ウェブは実際に
は多数の分離したウェブに分割されない。Therefore, in this cutting operation, the laminated web is not actually divided into a number of separate webs.

その代りに、生成された切口は、引続いての前進で切口

ことが適当である。However, in some cases, adhesion between the layers may make separation of said layers extremely difficult, and in such cases lower lamination pressures may be applied, for example by application of a sealing inhibitor. In addition, during the manufacture of the laminate material, it is appropriate to facilitate the separation between the layer 2 of the covering material and the base layer 1 by providing poor adhesion strength in areas where separation is desired.
