Description

Längsfalznaht für Konservendosen mit flüssig aufgebrachter Gununidichtung Es sind Hakenfalznähte als Längsnähte für die Rümpfe von Konservendosen bekannt, die eine aus flüssigem Gummi bestehende und in den Winkelraum des einen Hakens der Längsnaht eingebrachte Dichtung aufweisen.Longitudinal seam for cans with liquid applied Gununi seal Hook fold seams are known as longitudinal seams for the bodies of food cans, the one consisting of liquid rubber and into the angular space of one hook of the Have a longitudinal seam introduced seal.

Um eine erhebliche Gummiersparnis und trotzdem eine genügend sichere Dichtung für kochfeste Konservendosen zu erzielen, ist der Gummibelag gemäß der Erfindung nur auf dem geraden Stück des freien Hakenschenkels unter Ausschluß des Hakenwinkelraumes aufgebracht. Bevor man die hakenartig umgebogenen Blechränder des Dosenrumpfes in bekannter Weise vor der Erzeugung des Falzes zusammenhakt, ist .es zweckmäßig, den aufgetragenen flüssigen Gummi unter Anwendung von Wärme halbfest erstarren zu lassen, weil man dadurch die sichere Gewähr erlangt, daß beim Zusammenfalzen der Ränder die Gummimasse an den beiden Innenseiten der zusammenzuhakenden Blechränder gut dichtend anliegt.A considerable saving in rubber and still a sufficiently safe one To achieve a seal for boil-proof tin cans, the rubber lining is according to the Invention only on the straight piece of the free hook leg excluding the Hook angle space applied. Before the hook-like bent sheet metal edges of the can body coacts together in a known manner prior to the creation of the fold It is advisable to use heat to make the applied liquid rubber semi-solid to solidify, because one obtains the sure guarantee that when folding the edges the rubber compound on the two inner sides of the sheet metal edges to be hooked together fits tightly.

Auf der Zeichnung ist de neue Anordnung der Gummimasse dargestellt.The drawing shows the new arrangement of the rubber compound.

Fig. i zeigt im Schnitt die hakenartig abgebogenen Blechränder b, d eines Dosenruinpfes ca. An der Innenseite des abgebogenen Randes b, und zwar lediglich auf seinem geraden Stück unter Ausschluß des Hakenwinkelraumes, ist mit Hilfe einer an sich bekannten Auftragvorrichtung eine Schicht c von flüssigem Gummi aufgebracht. Dieser flüssige Gummi wird in einer Heizvorrichtung so lange mit Wärme behandelt, bis er halbfest erstarrt ist, eine Maßnahme aber, die nicht zur Erfindung gehört. Erst danach hakt man das nach unten umgebogene Ende d -des anderen Blechrandes eines Dosenrumpfes von oben ein, so daß die Innenseite des Randes d flach auf der halbfest erstarrten Gummi- Schicht c liegt. Hierauf werden die Blechränder b, d zu dem in Fig. 2 gezeichneten Falz zusammengedrückt.Fig. I shows in section the hook-like bent sheet metal edges b, d of a can body approx Rubber applied. This liquid rubber is treated with heat in a heating device until it has solidified in a semi-solid state, but a measure that does not belong to the invention. Only then is the downwardly bent end d of the other sheet metal edge of a can body hooked in from above, so that the inside of the edge d lies flat on the semi-solid, solidified rubber layer c. The sheet metal edges b, d are then pressed together to form the fold shown in FIG.
