Description

Die Erfindung betrifft ein Verfahren zum elektrostatischen Auftragen von länglichen Teilchen auf laufende mit Kleber bestrichene Gebilde, bei dem die Gebilde durch zusätzliche elektrische Gleichspannungsfelder zum Ausrichten der Teilchen geführt werden.The invention relates to a method for the electrostatic application of elongated particles to runners Structures coated with adhesive, in which the structures are activated by additional electrical direct voltage fields to align the particles.

Es ist bekannt, auf laufende Gebilde aufgebrachte Flocken vor der Trocknung in einem elektrischen Feld auszurichten. Bei elektrostatischer Beflockung wird z. B. gemäß der britischen Patentschrift 697 738 die Ausrichtung nach Umlenkung der zu beflockenden Bahn in einem zweiten, gegen das Beflockungsfeld senkrechten elektrischen Feld durchgeführt. It is known to apply flakes to running structures before drying in an electric Align field. With electrostatic flocking z. B. according to the British patent specification 697 738 the alignment after deflection of the web to be flocked in a second, against the flocking field perpendicular electric field carried out.

Bei den bekannten Auftragsverfahren ist es von Nachteil, daß ein erheblicher Teil der in die Aufgabezone gegebenen Flocken bzw. Kurzfasern trotz des Auf- und Abbewegens im Flockstrahl zwischen den Gegenständen und dem Aufgabesieb nicht im Kleber verankert wird. Die überschüssigen, kreuz und quer aufliegenden Flocken müssen entfernt werden. Ein zweiter, schwerwiegender Nachteil besteht darin, daß die einzelnen Fasern nicht senkrecht, sondern geneigt im Kleber stehen. Der beflockte Gegenstand erhält auf diese Weise einen Strich, der je nach den Beflockungsbedingungen gleichmäßig eine Richtung oder auch fleckenweise sich ändernde Richtung haben kann.In the known application process, it is disadvantageous that a considerable part of the in the application zone given flakes or short fibers despite the up and down movement in the flock jet between the Objects and the feeding screen is not anchored in the adhesive. The excess, criss-cross flakes lying on top must be removed. A second, serious disadvantage is that the individual fibers are not vertical but inclined in the adhesive. The flocked item receives in this way a line that, depending on the flocking conditions, has a uniform direction or can have a changing direction in spots.

Ziel der vorliegenden Erfindung ist es, das Auftragen der Teilchen, insbesondere Flocken oder Kurzfasern, zu verbessern durch eine geeignete Ausgestaltung des Beflockungsverfahrens.The aim of the present invention is to apply the particles, in particular flakes or Short fibers, to be improved by a suitable design of the flocking process.

Dieses Ziel wird erfindungsgemäß dadurch erreicht, daß die Gebilde durch eine Trockenzone geführt werden, in der zusätzliche elektrische Felder aufrechterhalten werden, welche die Teilchen in aufgerichteter Stellung bis zu ihrer Fixierung im Kleber halten. Hierdurch wird erreicht, daß die Flocken während der Trocknung des Klebers in aufgerichteter Stellung im Kleber gehalten werden, bis der angetrocknete Kleber eine Lageveränderung der Flocken nicht mehr zuläßt.This goal is achieved according to the invention in that the structures are passed through a drying zone, in which additional electric fields are maintained, which the particles in more erect Hold position until it is fixed in the adhesive. This ensures that the flakes during to dry the glue in the upright position in the glue until the dried Glue no longer allows a change in position of the flakes.

Damit keine Inhomogenität am Ende der zusätzlichen Felder selbst auftritt, läßt man die Feldstärke in Richtung der Bewegung abnehmen. Dies kann erreicht werden durch eine an fester Spannung liegende Flächenelektrode, deren Abstand von der anderen Flächenlelektrode zunimmt, oder durch mehrere, in konstantem Abstand angebrachte Elektroden, die an abnehmende Spannung gelegt werden. Diese Elektroden können aus Blech oder vorzugsweise in der Trockenzone aus Drahtnetzen oder gespannten Drähten bestehen.So that no inhomogeneity occurs at the end of the additional fields themselves, the field strength is left decrease in the direction of movement. This can be achieved by having a fixed tension Surface electrode whose distance from the other surface electrode increases, or by several, in electrodes placed at a constant distance and applied to decreasing voltage. These electrodes can be made of sheet metal or preferably in the dry zone from wire netting or tensioned Wires exist.
