Abstract

The shaft (3) has sieves comprising sieve surfaces (4) and attached to front sides (5) of the shaft. Extraction rollers (6) are provided for compressing stable fibers to a fiber blanket (8) directly in front of a fibrous web forming-textile machine, where the fibers are entered into the rollers through a supply line (1). The sieves are made from a perforated sheet, comb, reed, metal or plastic web.

Description

Zur Beschickung von Karden und Krempeln werden in der Textilindustrie Speiseschächte eingesetzt. Seit 1960 ist die gebräuchlichste Ausführungsform ein Schacht mit einer oberen Einblaszone mit Siebflächenzone über die Arbeitsbreite gefolgt von mindestens einer Zuführwalze und einer Öffnungswalze und einer zweiten Schachtabteilung und an einer zweiten Siebflächenzone etwa über die Arbeitsbreite. Ein Luftstrom verdichtet die Fasern. Die Siebzonen können an einer oder an beiden Arbeitsbreitenseiten angebracht sein. Ein Walzenpaar oder eine Walzen-Muldenkompensation zieht die gebildete Fasermatte ab und führt sie der Karde oder Krempel zu. Problematisch sind die linken und rechten Randzonen der gebildeten Fasermatte. Diese fallen in der Regel weniger dicht aus; dies ist nachteilig für die Weiterverarbeitung.to Feeding of cards and cardboards are used in the textile industry food trays used. Since 1960 is the most common embodiment a shaft with an upper blowing zone with Siebflächenzone over the Working width followed by at least one feed roller and an opening roller and a second manhole section and at a second screen surface zone about about the working width. An air stream compresses the fibers. The sieve zones can be attached to one or both sides of the work. One Roller pair or a roller-depression compensation pulls the formed Fiber mat off and leads they use the card or clutter too. Problematic are the left and right edge zones of the formed fiber mat. These usually fall less dense; This is disadvantageous for further processing.

Aufgabe der Erfindung ist es, dies auf einfache Weise zu vermeiden. Dies geschieht, indem im Bereich der Siebzone auch die die seitlichen Schachtwände bildenden Flächen als Siebflächen ausgebildet sind. Hierdurch kann die Luft auch an den Seiten entweichen und verdichtet die Fasern dort wie in dem Mittelbereich.task The invention is to avoid this in a simple manner. This happens by also forming the lateral shaft walls in the area of the screening zone surfaces designed as screen surfaces are. This allows the air to escape on the sides and compacts the fibers there as in the middle area.

1 zeigt schematisch einen einfachen Beschickungsschacht mit nur einer Kammer für vliesbildende Maschinen. Die Stapelfasern gelangen durch eine Zuführleitung 1) in den Verteilteil 2) des Schachtes 3). Die Fasern lagern sich wie bekannt an den Siebflächen 4) über die Arbeitsbreite ab. Zusätzlich sind Siebflächen an den Stirnseiten 5) angebracht. 1 schematically shows a simple feed chute with only one chamber for web-forming machines. The staple fibers pass through a feed line 1 ) in the distribution part 2 ) of the shaft 3 ). The fibers deposit as known on the screen surfaces 4 ) over the working width. In addition, there are screen surfaces on the front sides 5 ) appropriate.

Die Fasern werden zur Fasermatte durch die Auszugswalzen 6) zusammengedrückt und aus dem Schacht abgezogen. Über ein Rutschblech 7) gelangt die Fasermatte 8) zur vliesbildenden Maschine.The fibers become the fiber mat through the extraction rollers 6 ) and pulled out of the shaft. About a slide plate 7 ) passes the fiber mat 8th ) to the web-forming machine.

Claims (4)
