Claims (23)
- - Bereitstellen eines Streifens faserartigen Filterma terials, der zwei im wesentlichen parallele, längsverlau fende Streifenkanten oder -ränder sowie eine erste Fläche auf einer Seite des Filtermaterials und eine zweite Fläche auf der anderen Seite des Filtermaterials aufweist,
- - Anbringen eines Falzes in Längsrichtung des Strei fens und Bearbeiten des einen Falz aufweisenden Streifens, so daß er eine flache Form annimmt,
- - Übereinanderanordnen der beiden übereinander gefal teten Lagen aus Filtermaterial an dem Filterboden und an einer der beiden Filterseiten
- - Schneiden des Filtermaterials und hierdurch Formen von getrennten Filtertüten, dadurch gekennzeichnet, daß das Verfahren des weiteren umfaßt:
- - Verbinden der beiden längsverlaufenden Streifenkan ten oder -ränder des Streifens durch eine ununterbrochene, längsverlaufende Verbindung, so daß ein Schlauch aus Fil termaterial entsteht,
- - Abflachen des Schlauchs zu einem flachen Schlauch mit zwei übereinander angeordneten Lagen Filtermaterial, der zwei parallele, längsverlaufende Schlauchkanten oder -ränder, die einander gegenüberliegen, und zwei im wesent lichen flache, einander gegenüberliegende Außenflächen auf weist
- - Formen zweier Filtertüten nebeneinander über die Breite des abgeflachten Schlauchs, mit ersten Filterseiten entlang der jeweiligen gegenüberliegenden Schlauchkanten und mit zweiten Filterseiten, die einander zugewandt sind.
- Providing a strip of fibrous filter material which has two substantially parallel, longitudinally extending strip edges or edges and a first surface on one side of the filter material and a second surface on the other side of the filter material,
- Applying a fold in the longitudinal direction of the strip and machining the strip having a fold so that it takes on a flat shape,
- - Arranging the two layers of filter material folded on top of each other on the filter base and on one of the two filter sides
- - Cutting the filter material and thereby forming separate filter bags, characterized in that the method further comprises:
- - Connecting the two longitudinal Streifenkan th or edges of the strip by an uninterrupted, longitudinal connection, so that a tube of filter material is formed,
- - Flattening the hose to a flat hose with two layers of filter material arranged one above the other, which has two parallel, longitudinally running hose edges or edges, which lie opposite one another, and two essentially flat, opposite outer surfaces
- - Forming two filter bags side by side over the width of the flattened hose, with first filter sides along the respective opposite hose edges and with second filter sides that face each other.
daß die zweiten Filterseiten in Bezug auf die längs verlaufende Mittellinie des abgeflachten Schlauchs in einem Winkel verlaufen und
daß die Verbindung die zweiten Seiten aller Filtertü ten an entsprechenden Stellen schneidet.9. Filter bags according to claim 6, characterized in
that the second filter sides are at an angle with respect to the longitudinal center line of the flattened tube and
that the connection cuts the second sides of all Filtertü th at appropriate locations.
daß die zweiten Filterseiten in Bezug auf die längs verlaufende Mittellinie des abgeflachten Schlauchs in einem Winkel verläuft und
die Verbindung lediglich die zweiten Filterseiten der jenigen Filtertüten schneidet, deren erste Filterseiten an die gleiche Schlauchkante angrenzen.10. Filter bags according to claim 6, characterized in that
that the second filter sides are at an angle with respect to the longitudinal center line of the flattened tube and
the connection only cuts the second filter sides of those filter bags, the first filter sides of which adjoin the same hose edge.
daß der abgeflachte Schlauch mit Teilschnitten verse hen und als Folge hiervon zu einem Schlauch geformt ist, von dem einzelne Filtertüten von Hand abgetrennt werden können, und
daß nach Anbringen der Teilschnitte ein Teil des abge flachten Schlauchs, der eine solche Länge aufweist, daß in Längsrichtung betrachtet eine Mehrzahl von Filtertüten ne beneinander vorliegen, im wesentlichen ohne Abtrennung ein zelner Teile verpackt wird, zur Auslieferung an einen Ver braucher. 17. Filter bags according to claim 1, characterized in
that the flattened hose with partial cuts hen and as a result of this is formed into a hose from which individual filter bags can be separated by hand, and
that after making the partial cuts a part of the flattened hose, which is of such a length that, viewed in the longitudinal direction, a plurality of filter bags are present next to one another, essentially without separation, individual parts are packed for delivery to a consumer.
daß durch eine der beiden Filterwände eine Verbindung verläuft, die eine der Filterseiten in einem Winkel schnei det, und
daß die betreffende Filterseite und die Verbindung an einander angrenzen.19. Filter bag, produced according to a method as in claim 1, wherein the filter bag in the flat state has approximately the shape of an isosceles trapezoid with a filter base on which the two layers of filter material are not connected, a filter base which is opposite the filter base and runs essentially parallel to this and is shorter than this and on which the two layers of filter material are connected to one another, two filter sides on which the two layers of filter material are connected to one another, and two filter walls which are located between the filter strings, the filter base and the filter base extend, the filter walls are not connected to each other, so that a filter bag is formed which is open at the base and has a filter container space between the filter walls, the filter sides and the filter bottom, characterized in that
that runs through one of the two filter walls, which cuts one of the filter sides at an angle, and
that the relevant filter side and the connection adjoin each other.
