Description
ZS:ngsfalzeinrichtung an Rotationsmaschinen mit vertikal arbeitendem Falzmesser. Längsfalzeinrichtungen an Rotations maschinen mit vertikal arbeitendem Falz messer sind bekannt. Sie werden vorzugs weise dort angewendet, wo man Wert auf einen genauen Falz legt, haben jedoch den Nachteil, dass bei genauer Parallelführung der Falzmesser die Geschwindigkeit dersel ben begrenzt ist. Man kennt für den Längs falz auch rotierende Einrichtungen, welche zwar mit grösserer Geschwindigkeit arbeiten, aber weniger genaue Produkte liefern als das Falzmesser mit seiner geradlinigen Füh rung.
Gemäss der Erfindung wird eine Längs- falzeinrichtung mit vertikal arbeitendem Falzmesser benutzt, deren Kennzeichen darin besteht, dass das Falzmesser sowohl bei der Aufwärts- wie auch bei der Abwärtsbewe gung eine Falztätigkeit ausübt.
Diese Einrichtung hat ausser der grösse ren Leistungsfähigkeit auch noch die Mög lichkeit, dass zwei unterschiedliche Druck schriften ausgelegt werden können, was bei bisher bekannten Einrichtungen nicht der Fall war.
Auf der Zeichnung ist eine Längsfalz einrichtung gemäss der Erfindung beispiels weise schematisch dargestellt, und zwar zeigt Fig. 1 einen Aufriss und Fig. 2 einen Quer schnitt.
Die vom Falzzylinder 1 (Fig. 1) quer gefalzten Bogen werden mittels beweglicher Zungen 2 und 8 entweder zu den obern Füh rungsbändern 4 oder zu den untern Füh rungsbändern 5 geleitet. Durch die obern Führungsbänder 4 werden die Bogen über einen Falztisch 6 geführt, durch welchen bei 7 das sich vertikal auf- und abbewegende Falzmesser 8 hindurchgreift und die gefalz ten Bogen zwischen die Führungsbänder 9 stösst, mittels deren sie zu dem Ausleger 10 geführt werden.
Die Führungsbänder 5 füh ren die Bogen über den Falztisch 11, durch dessen Schlitz 12 das Falzmesser 8 greift, um die gefalzten Bogen den Führungsbän dern 18 zu übergeben, durch die sie zu dem Ausleger 14 geführt werden.
ZS: ngsfalzeinrichtung on rotary machines with vertically working folding blades. Longitudinal folding devices on rotary machines with vertically operating folding blades are known. They are preferably used where a precise fold is important, but have the disadvantage that the speed of the same is limited if the folding knives are guided precisely in parallel. Rotating devices are also known for the longitudinal fold, which work at greater speed but deliver less precise products than the folding knife with its straight-line guide.
According to the invention, a longitudinal folding device with vertically operating folding blades is used, the characteristic of which is that the folding blade performs a folding activity both during the upward and downward movement.
In addition to the greater capacity, this facility also has the option of using two different printed fonts, which was not the case with previously known facilities.
In the drawing, a longitudinal folding device according to the invention is shown schematically as an example, namely Fig. 1 shows an elevation and Fig. 2 shows a cross section.
The sheets folded transversely by the folding cylinder 1 (FIG. 1) are passed by means of movable tongues 2 and 8 either to the upper guide belts 4 or to the lower guide belts 5. Through the upper guide bands 4, the sheets are guided over a folding table 6, through which at 7 the vertically moving up and down folding knife 8 engages and the folded sheet pushes between the guide bands 9, by means of which they are guided to the boom 10.
The guide bands 5 lead the sheets over the folding table 11, through the slot 12 of which the folding knife 8 engages to pass the folded sheets to the Führbän countries 18 through which they are guided to the boom 14.
