Description

KAISERLICHESIMPERIAL

Pappschachteln mit abgerundeten Ecken bezw. deren Theile (Schachtel und Deckel) stellt man aus. einem Stück Pappe durch Prägung her. So gestaltete Pappschachteln haben gröfsere Steifigkeit und Widerstandsfähigkeit, als solche mit scharfen Ecken. Die gleichen Vorzüge auch grofsen Versandkasten z. B. aus Pappe zuzuwenden, war bisher unthunlich, weil eben zufolge ihrer Gröfse die für ihre Herstellung mittelst Prägung erforderlichen Prägformen sehr grofs sein müfsten und demzufolge zu kostspielig und unhandlich werden würden, auch würde das Prägen einen bedeutenden Kraftaufwand erfordern. Ferner aber würde die Mannigfaltigkeit in den Gröfsen solcher Kasten ebenso mannigfaltige Prägformen erfordern, für die sich ein unverhältnifsmäfsiger Kostenaufwand nöthig machte.Cardboard boxes with rounded corners or its parts (box and lid) one off. a piece of cardboard by embossing. Have cardboard boxes designed like this greater rigidity and resistance than those with sharp corners. The same Advantages also large shipping boxes z. B. to turn to cardboard was previously impractical, because, according to their size, they are necessary for their production by means of embossing Embossing forms would have to be very large and consequently would become too expensive and unwieldy, and embossing would also make one require significant effort. But further would the multiplicity in sizes Such sets require just as diverse forms of embossing, for which a disproportionate Made costs necessary.

Ein Verfahren, um auch Deckel bezw. Deckel und Böden für grofse Pappkasten der verschiedensten Abmessungen mit abgerundeten Ecken aus einem Stück Pappe, und zwar mittelst nur einer Prä'gform herstellen zu können, ohne* dazu kostspieliger Einrichtungen und hohen Kraftaufwandes zu bedürfen, bildet den Gegenstand der vorliegenden Erfindung.A method to also cover bezw. Lids and bases for large cardboard boxes various dimensions with rounded corners from one piece of cardboard, namely to be able to produce by means of only one embossing form, without additional expensive equipment and to require high expenditure of force, forms the subject of the present invention.

An einem zu einem Kastendeckel oder -Boden zugeschnittenen Pappstück (Fig. 1) werden für die durch das spätere Aufbiegen des Randstreifens des Pappstückes zu bildenden Ränder zunächst die geraden Längen für das Aufbiegen dadurch vorbereitet, dafs an ihren Biegestellen α mittelst einer der hierzu geeigneten bekannten Vorrichtungen Rillen gebildet werden (Fig. 2 und 3), deren Jede an ihren beiden Enden allmählig verläuft.On a piece of cardboard cut into a box lid or bottom (Fig. 1), the straight lengths for the edges to be formed by the later bending of the edge strip of the piece of cardboard are first prepared by using one of the known ones suitable for this at their bending points α Devices grooves are formed (Figs. 2 and 3), each of which is gradual at its two ends.

Hierauf werden mittelst einer ebenfalls bekannten , aus einem feststehenden Untertheil mit auf seiner oberen Fläche vorfindlichen Faltenhalter und einem senkrecht bewegbaren Oberstempel bestehenden, für das Aufbiegen eines einen Viertelkreis bildenden Randtheils eingerichteten Ziehform die je an zwei der geraden Randtheile anschliefsenden vier bogenförmigen Randtheile b nach einander aufgebogen. Then, by means of a drawing form, which is also known, consists of a fixed lower part with a fold holder on its upper surface and a vertically movable upper punch, which is set up for the bending of an edge part forming a quarter circle, the four curved edge parts b adjoining two of the straight edge parts are bent up one after the other .

Beim Aufbiegen jedes dieser ' Randtheile werden die an dasselbe anschliefsenden geraden Randtheile zu einem Theil ihrer Länge mitgenommen, d. h. ebenfalls aufgebogen. Um dies zu ermöglichen, sind ihre Biegestellen a, wie früher erwähnt, zuvor durch in ihnen gebildete Rillen biegsam gemacht.When each of these edge parts is bent up, the straight edge parts adjoining it are taken along for part of their length, that is, they are also bent up. To make this possible, their bending points a, as mentioned earlier, are previously made flexible by grooves formed in them.

Nach vollendeter Herstellung der bogenförmigen Randtheile bedürfen die geraden Randtheile nur in der Mitte ihrer Länge einer kleinen Nachhülfe von Hand, um sie in die zur Bodenfläche senkrechte Stellung zu bringen und dadurch einen Kastendeckel oder -Boden so fertig zu stellen, wie ihn Fig. 4 und 5 zeigen.After the curved edge parts have been completed, the straight ones are required Edge parts only in the middle of their length a little help by hand to put them into the to bring it in a perpendicular position to the floor surface and thereby create a box lid or floor to be finished as shown in FIGS. 4 and 5.

In solchen Fällen, in welchen die Abrundungen zweier Ecken unmittelbar in einander übergehen, also zusammen einen Halbkreis bilden, wie in Fig. 6, oder wenn der zwischen zwei solchen Abrundungen liegendeIn such cases, in which the rounding of two corners directly into each other pass over, so together form a semicircle, as in Fig. 6, or if the lying between two such roundings

gerade Randtheil nur kurz ist, kann man beide Eckabrundungen bezw. diese und das gerade Stück mittelst einer Prägung formen.just edge part is only short, you can bezw both corner roundings. this and that right now Shape the piece by means of an embossing.
