Filtertüten aus Papier für Filtergefäße in Tassen- oder KegelstumpfformFilter bags of paper for filter vessels in the shape of a cup or a truncated cone
Filtertüten aus Papier für Filtergefäße in Tassen- oder Ke gel stumpf form sind bereits bekannt. Zumeist werden diese Tüten dadurch hergestellt, daß man zwei Papierbahnen übereinander legt, gegebenenfalls die entsprechende Tassenform ausstanzt, und dann drei Seiten rändelt oder man stanzt einen Zuschnitt aus, der zur Tassenform einmal gefaltet wird, und rändelt eine Seite und die Bodenseite. Man hat auch schon Tüten aus trapez- und halbkreisförmigem Zuschnitt gefaltet und die hierbei entstehende Tütenspitze nach oben abgeknickt, so daß der Tütenboden eine der Tassenform entsprechende länge erhielt. Bei den bekannten Filtertüten ist jedoch die Zuverlässigkeit beim Filtrieren nicht voll gewährleistet oder der Papierabfall bei ihrem Zuschnitt ist zu groß oder die Zahl der Arbeitsgänge verteuert die Herstellung der Filtertüten.Paper filter bags for filter vessels in cups or cone gel blunt shape are already known. Mostly be these bags are made by laying two webs of paper on top of each other, optionally the corresponding one Punch out the cup shape, and then knurl three sides or you punch out a blank that becomes the cup shape once is folded, and knurls one side and the bottom side. You also have bags made of trapezoidal and semicircular shapes Folded blank and the resulting bag tip bent upwards so that the bottom of the bag is one of the shape of a cup corresponding length received. In the case of the known filter bags, however, the reliability in filtering is not fully guaranteed or the paper waste when cutting them is too large or the number of operations makes them more expensive Manufacture of the filter bags.

Es wurde nun gefunden, daß man in einfacher Weise ohne oder nur bei geringem Papierabfall Filtertüten herstellen kann, indem man einen rechteckigen Zuschnitt, der an seinen Schmalseiten noch eine oder zwei Ecken wie in Fig. 1 aufweist, in der Mittellinie a faltet und dann - gegebenenfalls durch 2 Walzen - aie Pragelinien b anbringt und möglichst gleichzeitig an den Seiten c rändelt, wie in Fig. 2 wiedergegeben ist. Durch Umlegen der gerändelten Ecken um die Prägelinien b erhält man eine Filtertüte, wie sie aus den Fig. 3 und 4 ersichtlich ist.It has now been found that filter bags can be produced in a simple manner with little or no paper waste, by making a rectangular blank which still has one or two corners on its narrow sides as in Fig. 1, folds in the center line a and then - if necessary by means of 2 rollers - attaches aie embossing lines b and knurls as simultaneously as possible on the sides c, as shown in FIG. By turning the knurled At corners around the embossed lines b, a filter bag is obtained, as can be seen from FIGS. 3 and 4.
Die Herstellung dieser Tüten kann auch kontinuierlich durchgeführt werden, indem man eine Papierbahn in der Mitte faltet und dann durch zwei Walzen laufen laßt, zwischen denen die Filtertüten ausgestanzt, die Prägelinien b für die Umlegekanten eingedrückt und die offenen Seiten c gegebenenfalls gerändelt werden. Abgesehen davon, daß diese Filtertüten mit nur sehr geringen Mengen an Abfallpapier oder sogar ohne Abfall hergestellt werden können, haben diese Tüten den Yorteil der unbedingten Zuverlässigkeit beim Filtrieren. Ferner haben sie neben ihrer einfachen Herstellung den Vorteil der leichten Anwendbarkeit, ob sie nun in den Prägelinien b vorgefaltet oder an dieser Stelle nicht umgelegt in den Verkehr gebracht werden.The production of these bags can also be carried out continuously by folding a paper web in half and then running it through two rollers between them the filter bags punched out, the embossed lines b for the fold-over edges pressed in and the open sides c if necessary be knurled. Apart from that these filter bags contain only very small amounts of waste paper or even can be produced without waste, these bags have the advantage of absolute reliability in filtering. In addition to their simple production, they also have the advantage of being easy to use, whether they are in the embossed lines b are placed on the market pre-folded or not folded down at this point.
