Description

Die Erfindung betrifft einen Formbodensack aus Papier, Kunststoffolie oder dgl. faltbarem Material mit einem Traggriff, bei dem zumindest einer der beiden Formböden auf seiner Außenseite einen sich in Bodenlängsrichtung beidseits einer mittleren Symmetrielinie erstreckenden Griffstreifen von im wesentlichen Bodenlänge trägt, der endseitige Verbindungsbereiche von in wesentlichen Bodenbreite und einen sich zwischen diesen erstreckenden und gegenüber diesen verschmälerten Tragbereich umfaßt, wobei der Griffstreifen einen Teil einer vorgefertigten Zuschnittseinheit bildet, die ein den Tragbereich des Griffstreifens verbindungsfrei untergreifendes Trennblatt umfaßt, dessen Breite der des Griffstreifens in dessen endseitigen Verbindungsbereichen entspricht und das mit dem Griffstreifen in schmalen Verbindungsbereichen beidseits dessen Tragbereichs vereinigt ist, und wobei die Zuschnittseinheit mit ihrer freien Unterseite als Ganzes mit der Außenseite des Formbodens, diesen nach Art eines Bodendeckblattes im wesentlichen vollständig abdeckend, verklebt ist.The invention relates to a molded bottom sack made of paper, plastic film or the like.Foldable material with a carrying handle, in which at least one of the two molded bases carries on its outside a grip strip which extends in the longitudinal direction of the base on both sides of a central line of symmetry and is essentially at the bottom length and which essentially connects the end regions Bottom width and a between them extending and narrowed the support area comprises, the grip strip forms part of a prefabricated cutting unit, which comprises a separating sheet engaging under the support area of the grip strip, the width of which corresponds to that of the grip strip in its end connection areas and that with the grip strip in narrow connection areas on both sides of its support area, and the cutting unit with its free underside as a whole with the outside of the mold base, this according to Ar t of a bottom cover sheet is essentially completely covered, glued.

Ein derartiger Formboden ist aus der DE-A-32 05 340 bekannt. Das Anbringen des gesonderten Griffstreifens in Verbindung mit einem die Außenkontur des Formbodens aufweisenden äußeren Bodendeckblatt ist bei diesem bekannten Formbodensack mit einem vergleichsweise hohen Herstellungs- und Materialaufwand verbunden und/oder der Griffstreifen ist aus verbindungs- oder materialtechnischen Gründen nur zur Aufnahme geringer Traglasten geeignet.Such a molded floor is known from DE-A-32 05 340. The attachment of the separate grip strip in connection with an outer bottom cover sheet having the outer contour of the mold base is associated with a comparatively high manufacturing and material expenditure in this known mold base sack and / or the grip strip is only suitable for absorbing low loads for connection or material reasons.

Der Erfindung liegt die Aufgabe zugrunde, einen Formbodensack aus Papier, Kunststoffolie oder dgl. faltbarem Material mit einem Traggriff zu schaffen, der einfach und mit geringen Materialaufwand herstellbar ist und ein hohes Maß an Tragfestigkeit besitzt.The invention has for its object to provide a molded bottom bag made of paper, plastic film or the like. Foldable material with a handle that is simple and low The cost of materials can be produced and has a high degree of load-bearing capacity.

Ausgehend von einem Formbodensack der eingangs angegebenen Art wird diese Aufgabe nach der Erfindung dadurch gelöst, daß die in Bodenlängsrichtung gemessene Länge des Trennblattes gegenüber der Länge des Griffstreifens bis auf die schmalen Verbindungsbereiche beidseits des Tragbereichs des Griffstreifens verkürzt ist und die mit der Außenseite des Formbodens verklebte Unterseite der Zuschnittseinheit aus den Unterseiten der endseitigen Verbindungsbereiche des Griffstreifens und der Unterseite des Trennblattes zusammengesetzt ist.Starting from a molded bottom sack of the type specified at the outset, this object is achieved according to the invention in that the length of the separating sheet measured in the longitudinal direction of the base is shortened compared to the length of the grip strip to the narrow connecting areas on both sides of the carrying area of the grip strip and which is glued to the outside of the molded base The underside of the cutting unit is composed of the undersides of the end connection areas of the grip strip and the underside of the separating sheet.

Der erfindungsgemäße Formbodensack mit Traggriff kann auf einfache Weise dadurch hergestellt werden, daß von einer ersten Materialbahn, deren Breite der Länge des Formbodens entspricht, in der Breite des Formbodens entsprechenden Abständen Langlöcher mit sich quer zur ersten Materialbahn erstreckender Längsmittellinie ausgestanzt werden, eine zweite Materialbahn, deren Breite das Längsmaß der in die erste Materialbahn eingestanzten Langlöcher beidseitig überragt, jedoch geringer ist als die Breite der ersten Materialbahn, mit ihrer Oberseite mit der Unterseite der ersten Materialbahn in ihren das Längsmaß der Langlöcher der ersten Materialbahn überrragenden Randbereichen vereinigt wird, die vereinigten Materialbahnen durch Quertrennschnitte entlang den Längsmittellinien der Stanzlöcher in einzelne Zuschnittseinheiten unterteilt werden und jede Zuschnittseinheit mit ihrer Unterseite mit der Außenseite eines Formbodens eine Formbodensackes verklebt wird.The molded-bottom sack according to the invention with a handle can be produced in a simple manner by punching oblong holes with a longitudinal center line extending transversely to the first material web from a first material web, the width of which corresponds to the length of the mold base, corresponding distances in the width of the mold base, a second material web, the width of which extends beyond the longitudinal dimension of the elongated holes punched into the first material web, but is less than the width of the first material web, with its upper side being united with the underside of the first material web in its edge regions projecting beyond the longitudinal dimension of the elongated holes of the first material web, the combined material webs can be divided into individual cutting units by cross-cutting along the longitudinal center lines of the punched holes, and each cutting unit is glued with its underside to the outside of a molded base of a molded base sack.

Dies ermöglicht eine vollmaschinelle Herstellung, in deren Zuge die Zuschnittseinheit mit den üblichen Maschinenaggregaten, beispielsweise einer an sich bekannten Vorrichtung zum Aufbringen von Bodendeckblättern, auf den Formboden aufgebracht werden kann. Dabei kann es sich empfehlen, die vereinigten Materialbahnen vor ihrer Unterteilung in einzelne Zuschnittseinheiten auf eine Vorratsrolle aufzuwickeln und zur Durchführung des Unterteilungsschrittes von der Vorratsrolle wieder abzuwickeln, nachdem diese in eine Sackherstellungsmaschine zur Versorgung der Aufbringvorrichtung eingesetzt worden ist.This enables fully automated production, in the course of which the cutting unit can be applied to the mold base with the usual machine units, for example a device for applying bottom cover sheets known per se. It may be advisable to combine the material webs before dividing them into individual cutting units wind up on a supply roll and unwind from the supply roll to carry out the subdivision step after it has been inserted into a sack manufacturing machine to supply the application device.

Bei der erfindungsgemäßen Ausgestaltung des Formbodensackes mit Traggriff erfüllt die Zuschnittseinheit die Funktion eines äußeren Bodendeckblattes des Formbodens und zugleich eines Traggriffs mit geringem Materialverbrauch, da nach der Erfindung die endseitigen Verbindungsbereiche des Griffstreifens und das Trennblatt gemeinsam mit ihren in dieser Weise zusammengesetzten Unterseiten einen kombinierten Materialzuschnitt von der Kontur des Formbodens entsprechender Kontur wie bei einem normalerweise einteiligen Bodendeckblatt bilden. Gleichzeitig besitzt aber der Traggriff aufgrund seiner der Bodenbreite entsprechenden, großflächigen Verbindungsbereiche mit dem Boden ein hohes Maß an Tragfestigkeit, ohne daß aufgrund des gegenüber den Verbindungsbereichen verschmälerten Tragbereichs des Griffstreifens der Tragkomfort für den Benutzer beeinträchtigt wird.In the inventive design of the molded bottom bag with a handle, the cutting unit fulfills the function of an outer bottom cover sheet of the molded base and at the same time a carrying handle with low material consumption, since according to the invention the end connection areas of the handle strip and the separating sheet together with their undersides assembled in this way have a combined material cut of form the contour of the mold base corresponding contour as with a normally one-piece bottom cover sheet. At the same time, however, the carrying handle has a large degree of load-bearing capacity due to its large-area connection areas corresponding to the floor width, without the wearing comfort for the user being impaired due to the reduced carrying area of the grip strip compared to the connecting areas.

Die Fig. 1 zeigt einen als Ganzes mit 1 bezeichneten Formbodensack, der aus Papier, Kunststoffolie oder dgl. faltbarem bzw. flexiblem Material bestehen kann. Der Formbodensack besitzt die Form eines Kreuzbodensackes und ist in Fig. 1 im Leerzustand gezeigt, in dem die beiden Sackwände 2 flach aneinanderliegen. Der obere Formboden 3 ist in die Ebene der vorderen Sackwand 2 geklappt, während der untere Formboden auf die gegenüberliegende Sackwand geklappt ist und daher nicht zur Darstellung kommt. Der Formboden 3 umfaßt die bei Kreuzböden üblichen einander paarweise gegenüberliegenden Eckeinschläge 4 und Bodenseitenumschläge 5.1 shows a molded base bag, designated as a whole by 1, made of paper, plastic film or the like. Foldable or flexible material can exist. The shaped bottom sack has the shape of a cross bottom sack and is shown in FIG. 1 in the empty state, in which the two sack walls 2 lie flat against one another. The upper mold base 3 is folded into the plane of the front sack wall 2, while the lower mold base is folded onto the opposite sack wall and is therefore not shown. The shaped bottom 3 comprises the corner inserts 4 and bottom side envelopes 5 which are usual in pairs on cross bottoms.

Auf den Formboden 3 ist eine Zuschnittseinheit 6, deren Kontur derjenigen des Formbodens 3 entspricht, jedoch etwas kleiner bemessen ist als diese, mit ihrer Unterseite aufgeklebt. Die Zuschnittseinheit 6 umfaßt einen Griffstreifen 7, der sich in Bodenlängsrichtung beidseits einer mittleren Symmetrielinie 8 des Bodens 3 erstreckt und im wesentlichen die gleiche Länge wie der Formboden 3 aufweist, wie sie sich im gefüllten, quaderförmigen Zustand des Formbodensackes 1 (Fig. 2) ergibt. Der Griffstreifen 7 besitzt an seinen Enden Verbindungsbereiche 9, deren Breite derjenigen des Formbodens 3 entspricht. Zwischen den beiden Verbindungsbereichen 9 erstreckt sich ein gegenüber diesen verschmälerter mittlerer Tragbereich 10.A cutting unit 6, the contour of which corresponds to that of the mold base 3, but is dimensioned somewhat smaller than this, is glued to the bottom 3 of the mold base 3. The cutting unit 6 comprises a grip strip 7 which extends in the longitudinal direction of the base on both sides of a central line of symmetry 8 of the base 3 and has essentially the same length as the molded base 3 as it results in the filled, cuboid shape of the molded base bag 1 (Fig. 2) . The grip strip 7 has connection areas 9 at its ends, the width of which corresponds to that of the mold base 3. Between the two connection areas 9, a central support area 10 which is narrower than this extends.

Die Zuschnittseinheit 6 umfaßt ferner ein den Tragbereich 10 des Griffstreifens 7 verbindungsfrei untergreifendes Trennblatt 11. Die Breite des Trennblattes 11 ist gleich der Breite der endseitigen Verbindungsbereiche 9 des Griffstreifens 7. Die in Bodenlängsrichtung, d.h. parallel zur Symmetrielinie 8, gemessene Länge des Trennblattes 11 ist gegenüber der Länge des Griffstreifens 7 bis auf schmale Verbindungsbereiche 12 beidseits des Tragbereichs 10 des Griffstreifens 7 verkürzt. In diesen Verbindungsbereichen 12 sind das Trennblatt 11 und der Griffstreifen 7 miteinander jeweils durch eine Klebenaht 13 miteinander vereinigt, die sich quer zur mittleren Symmetrielinie 8 des Formbodens 3 erstrecken. Um einem Einreißen des Tragbereichs 10 des Griffstreifens 7 an den Übergängen in seine Verbindungsbereiche 9 entgegenzuwirken, geht der Tragbereich 10 beidseits der mittleren Symmetrielinie 8 an seinen beiden Enden jeweils mit einem abgerundeten Endteil seines Außenrandes in den angrenzenden, rechtwinklig zur Symmetrielinie 8 verlaufenden Außenrand der Verbindungsbereiche 9 des Griffstreifens 7 über.The cutting unit 6 further comprises a separating sheet 11 which engages under the support area 10 of the grip strip 7 without connection. The width of the separating sheet 11 is equal to the width of the end connecting areas 9 of the grip strip 7. The length of the separating sheet 11 measured in the longitudinal direction of the floor, ie parallel to the line of symmetry 8 shortened compared to the length of the grip strip 7 to narrow connection areas 12 on both sides of the support area 10 of the grip strip 7. In these connection areas 12, the separating sheet 11 and the grip strip 7 are in each case united by an adhesive seam 13, which extend transversely to the central line of symmetry 8 of the mold base 3. In order to counteract tearing of the support area 10 of the grip strip 7 at the transitions into its connecting areas 9, the support area 10 goes on both sides of the middle line of symmetry 8 at both ends with a rounded end part of its outer edge in the adjacent, perpendicular to the line of symmetry 8 extending outer edge of the connecting areas 9 of the grip strip 7 over.

Die Zuschnittseinheit 6 ist mit ihrer freien, von den Unterseiten der endseitigen Verbindungsbereiche 9 des Griffstreifens 7 und der Unterseite des Trennblattes 10 zusammengesetzten Unterseite mit Hilfe eines auf dieser angebrachten vollflächigen Klebstoffauftrags als Ganzes mit der Außenseite des Formbodens 3 verklebt, derart, daß die Außenseite des Formbodens 3 nach Art eines Bodendeckblattes im wesentlichen vollständig von der Zuschnittseinheit 6 abgedeckt ist. Im gefüllten Zustand des Formbodensackes 1, wie er in Fig. 2 dargestellt ist, kann der Tragbereich 10 des Griffstreifens 7 gegenüber dem mit seiner Oberseite verbindungsfrei darunterliegenden Trennblatt 11 ohne weiteres vom Benutzer zum Tragen des Formbodensackes 1 erfaßt werden.The cutting unit 6 is glued with its free, from the undersides of the end connection areas 9 of the grip strip 7 and the underside of the separating sheet 10 underside with the help of a full-surface adhesive application attached thereon as a whole to the outside of the mold base 3, such that the outside of the Molded base 3 is essentially completely covered by the cutting unit 6 in the manner of a base cover sheet. In the filled state of the molded bottom bag 1, as shown in FIG. 2, the carrying area 10 of the grip strip 7 can be easily grasped by the user for carrying the molded bottom bag 1 with respect to the separating sheet 11 lying underneath with its top side without connection.

Zur Herstellung der Zuschnttseinheiten 6 wird von zwei Materialbahnen 14 und 15 ausgegangen, wie dies anhand der Fig. 3 und 4 im folgenden erläutert wird. Die Materialbahnen 14 und 15 können jeweils von einer geeigneten Kunststoffolie oder einem anderen Material mit den erforderlichen Eigenschaften hinsichtlich Verarbeitbarkeit und Festigkeit gebildet sein. Die Materialbahnen 14 und 15 werden von in der Zeichnung nicht näher dargestellten Vorratsrollen abgewickelt und einzelnen Bearbeitungsstationen zugeführt.For the production of the cutting units 6, two material webs 14 and 15 are assumed, as will be explained below with reference to FIGS. 3 and 4. The material webs 14 and 15 can each be formed from a suitable plastic film or another material with the required properties with regard to processability and strength. The material webs 14 and 15 are unwound from supply rolls, not shown in the drawing, and fed to individual processing stations.

Die Materialbahn 14 entspricht in ihrer Breite der Länge des Formbodens 3 und wird über Umlenkrollen 16 und 17 einer Lochstanzstation 18 mittels nicht näher dargestellter Vorzugeinrichtungen zugeführt. Die Lochstanzstation 18 umfaßt eine Schneidtrommel 19 mit auf ihrem Umfang in gleichmäßigen Abständen verteilten Stanzwerkzeugen 20, die verstellbar in Ausnehmungen 21 der Schneidtrommel 19 angebracht sind. Mit der Schneidtrommel 19 arbeitet eine Gegendruckwalze 22 zusammen, wobei die Bahn 14 zur Durchführung eines Stanzvorgangs zwischen der Schneidtrommel 19 und der Gegendruckwalze 22 hindurchgeführt wird. Im weiteren Verlauf umschlingt die Bahn 14 die Schneidtrommel 19, die bereichsweise, der Kontur ihres Außenumfangs folgend, von einer Absaugvorrichtung 23 zum Absaugen von Stanzabfällen umgeben ist.The width of the material web 14 corresponds to the length of the mold base 3 and is fed via deflection rollers 16 and 17 to a punching station 18 by means of preferred devices (not shown). The punching station 18 comprises a cutting drum 19 with punching tools 20 distributed uniformly on its circumference, which are adjustably mounted in recesses 21 of the cutting drum 19. A counter-pressure roller 22 works together with the cutting drum 19, the web 14 being passed between the cutting drum 19 and the counter-pressure roller 22 in order to carry out a punching process. In the further course, the web 14 wraps around the cutting drum 19, which in some areas follows the contour of its outer circumference, by a suction device 23 for suctioning Punching waste is surrounded.

In der Lochstanzstation 18 werden in der Breite des Formbodens 3 entsprechenden Abständen Langlöcher 24 (Fig. 4) eingestanzt, deren Längsmittellinien 25 sich quer zur Materialbahn 14 erstrecken. Danach wird die Materialbahn 14 über weitere Umlenkrollen 26 und 27 einer Umlenkwalze 28 zugeführt, an der die Materialbahn 14 mit der Materialbahn 15 vereinigt wird.In the punching station 18, slots 24 (FIG. 4) corresponding to the width of the mold base 3 are punched in, the longitudinal center lines 25 of which extend transversely to the material web 14. The material web 14 is then fed via further deflection rollers 26 and 27 to a deflection roller 28, on which the material web 14 is combined with the material web 15.

Die Breite der Materialbahn 15 überragt beidseitig das Längsmaß der in die Materialbahn 14 eingestanzten Langlöcher 24, sie ist jedoch deutlich kleiner als die Breite der Materialbahn 14. Die Materialbahn 15 wird über eine Umlenkrolle 29 einer Klebstoffauftragvorrichtung 30 zugeführt, die zwei Klebstoffauftragorgane 31 umfaßt, die auf einer Verbindungsschiene 32 in deren Längsrichtung verstellbar abgestützt sind. Mittels der Klebstoffauftragorgane 31 werden in Längsrichtung der Bahn 15 ununterbrochene, parallele, linienförmige Klebstoffaufträge 33 auf der Oberseite der Materialbahn 15 in deren die Querenden der Stanzlöcher 24 überragenden beiden Längsrandbereichen aufgebracht, die in der einzelnen Zuschnittseinheit 6 die Klebenähte 13 in den Verbindungsbereichen 12 bilden. Sodann läuft die auf ihrer Oberseite mit den Klebstoffaufträgen 33 versehene Materialbahn 15 an der Umlenkwalze 28, diese umschlingend, mit der Materialbahn 14 zusammen, die ihrerseits die Umlenkwalze 28 umschlingt und dabei mit ihrer Unterseite mit den Klebstoffaufträgen 33 auf der Oberseite der Materialbahn 15 verklebt wird.The width of the material web 15 projects on both sides beyond the longitudinal dimension of the elongated holes 24 punched into the material web 14, but it is significantly smaller than the width of the material web 14. The material web 15 is fed via a deflecting roller 29 to an adhesive application device 30 which comprises two adhesive application members 31 which are adjustably supported on a connecting rail 32 in the longitudinal direction thereof. By means of the adhesive application members 31, continuous, parallel, line-shaped adhesive applications 33 are applied in the longitudinal direction of the web 15 on the upper side of the material web 15 in the two longitudinal edge regions which protrude beyond the transverse ends of the punched holes 24 and which form the adhesive seams 13 in the connecting regions 12 in the individual cutting unit 6. Then the material web 15 provided on its upper side with the adhesive applications 33 runs around the deflecting roller 28, wrapping it around it, with the material web 14, which in turn wraps around the deflecting roller 28 and is glued with its underside to the adhesive applications 33 on the upper side of the material web 15 .

Die beiden auf diese Weise vereinigten Materialbahnen 14 und 15 könne sodann auf eine Vorratsrolle aufgewickelt werden, die bedarfsweise in eine Sackherstellungsmaschine eingesetzt wird, um eine Vorrichtung zum Aufbringen der Zuschnittseinheiten 6 auf die Außenseite eines Formbodens 3 zu versorgen. Hierbei werden mittels einer geeigneten Schneidvorrichtung von der von ihrer Vorratsrolle wieder abgewickelten Bahneinheit 14, 15 die einzelnen Zuschnitte 6 durch Quertrennschnitte entlang den Längsmittellinien 25 der Stanzlöcher 24 abgeteilt, sodann auf ihrer Unterseite mit einem vorzugsweise vollflächigen Klebstoffauftrag versehen und in nicht näher dargestellter Weise auf die Außenseite des Formbodens 3 eines Formbodensackes 1 in entsprechender Zuordnung aufgeklebt. Die Teilstücke der Bahn 14 bilden dabei den Griffstreifen 7, während die Teilstücke der Bahn 15 das Trennblatt 11 jeder Zuschnittseinheit 6 bilden.The two material webs 14 and 15 combined in this way can then be wound onto a supply roll which, if necessary, is inserted into a sack production machine in order to supply a device for applying the cutting units 6 to the outside of a mold base 3. Using a suitable cutting device, the individual blanks 6 are separated from the web unit 14, 15 unwound from their supply roll by cross-cutting along the longitudinal center lines 25 of the punched holes 24, then provided on their underside with a preferably full-surface adhesive application and in a manner not shown glued to the outside of the mold base 3 of a mold base bag 1 in a corresponding assignment. The sections of the web 14 form the grip strip 7, while the sections of the web 15 form the separating sheet 11 of each cutting unit 6.

Claims (7)

  1. A flat-bottomed bag (1) of paper, synthetic plastics film or like foldable material, with a carrying handle and in which at least one of the two shaped ends (3) carries on its outside and extending in the longitudinal direction of the end member, on both sides of a central line of symmetry (8), a handle strip (7) of substantially the same length as the end member, which comprises at its ends connecting areas (9) of substantially the width of the end member and, extending between and narrower than these latter, a carrier portion (10), the handle strip (7) forming a part of a prefabricated blank unit (6) comprising, engaging in unconnected fashion beneath the carrier portion (10) of the handle strip (7) a separating sheet (11) the width of which corresponds to that of the handle strip (7) in the terminal connecting areas (9) thereof and which is joined to the handle strip (7) in narrow connecting areas (12) on both sides of the carrier portion (10) thereof, the blank unit (6) having its free under side glued in its entirety to the outside of the shaped end (3), substantially completely covering this after the manner of an end cover sheet, characterised in that the length of the separating sheet (11) measured in the longitudinal direction of the end member is, in comparison with the length of the handle strip (7), shortened as far as the narrow connecting areas (12) on both sides of the carrier portion (10) of the handle strip (7), and the under side of the blank unit (6) which is glued to the outside of the shaped end member (3) is composed of the under sides of the terminal connecting areas (9) of the handle strip (7) and the under side of the separating sheet (11).
  2. A flat-bottomed bag according to claim 1, characterised in that the handle strip (7) and the separating sheet (11) are in their connecting areas (12) joined to each other by glued seams (13) extending crosswise to the central line of symmetry (8) through the shaped end member (3).
  3. A shaped end member according to claim 1 or 2, characterised in that on both sides of the central line of symmetry (8) of the shaped end member (3), the carrier portion (10) of the handle strip (7) has at both ends a rounded end part of its outer edge which merges into the adjacent outer edge of the connecting areas (9) of the handle strip (7) and which extends at right-angles to the line of symmetry (8).
  4. A method of manufacturing a flat-bottomed bag with a carrying handle according to claim 1, characterised in that from a first web (14) of material the width of which corresponds to the length of the shaped end member (3), elongate holes (24) having a longitudinal central line (25) extending crosswise to the first material web (14) are stamped out at intervals corresponding to the width of the shaped end member (3), a second web (15) of material, the width of which projects on both sides beyond the longitudinal dimension of the elongate holes (24) stamped into the first material web (14) but which is less than the width of the first material web (14), has its upper face connected to the under side of the first material web (14) in its marginal areas which extend beyond the longitudinal dimension of the elongate holes (24) in the first material web (14), the connected material webs (14, 15) being sub-divided into individual blank units (6) by transverse separating cuts made along the longitudinal central lines (25) of the elongate holes (24), each blank unit (6) having its under side glued to the outside of a shaped end member (3) of a flat-bottomed bag (1).
