Description

Die Erfindung hezieht sich auf eine Vorrichtung zum Ablegen fadenförmigen Materials auf thermoplastischem Kunststoff, bestehend aus Ablegerhülse, darin angeordnetem Heizstift, den Heizstift umgebender Heizspule (für elektrische Beheizung, z. B. Widerstandbeheizung) und angeschlossenem Fadenführer. The invention relates to an apparatus for depositing thread-like material on thermoplastic material, consisting of depositing sleeve, heating element arranged in it, heating coil surrounding the heating element (for electrical heating, e.g. Resistance heating) and connected thread guide.

Bei bekannten Vorrichtungen der beschriebenen Gattung (vgl. deutsche Auslegeschrift 1679 930) ist der Fadenführer ein Bauteil verhältnismäßig geringer Maße und an den Heizstift, der ebenfalls ein Bauteil verhältnismäßig geringer Maße darstellt, unmittelbar angeschlossen. Der Fadenfübrer seiest ist verhältnismäßig kompliziert geformt urd muß spanabhebend bearbeitet werden, er ist an den > <!eizstift mittels Klemmschraube angeklemmt. Durch ein Or in Form eines Nadelörs wird das fadenförmige Material in den Fadenführer eingeführt. Der Fadenführer oder sein Gleitfuß erweicht kurzfristig den thermoplastischen Kunststoff und drückt unmittelbar danach auch den Faden in dieses ein.In known devices of the type described (see. German Auslegeschrift 1679 930) the thread guide a component of relatively small dimensions and to the heating pin, which is also a component represents relatively small dimensions, directly connected. The thread feeder is proportional Complex shape and must be machined, it is at the> <! pen clamped by means of a clamping screw. Formed by an Or The thread-like material is introduced into the thread guide using a needle orifice. The thread guide or his The sliding foot briefly softens the thermoplastic material and immediately afterwards also presses the Thread into this one.

Das ist aus mehreren Gründen nachteilig. Einerseits läßt sich nicht verhindern, daß der Fadenführer, der über den thermoplastischen Kunststoff geführt wird, um diesen zunächst zu plastifizieren, Verschleißbeanspruchungen erfährt, und zwar weil der zu verlegende Draht zumeist von erheblicher Härte ist und sich folglich in den Fadenführer einarbeitet. Das macht nach Verschleiß häufiges Auswechseln des Fadenführers erforderlich. Ein Umsetzen des Fadenführers derart, daß die Kontaktfläche mit dem Draht nach Umsetzung unterschiedlich abgearbeitet wird, ist nicht durchführbar, da sich das Nadelör an einer Seite des Fadenführers befindet und dem zulaufenden Faden eindeutig zugeordnet ist. Darüber hinaus stört, daß der Fadenführer, aber auch der Heizstift nur verhältnismäßig geringe Maße darstellen und folglich kleine Wärmespeicher bilden. Das reduziert die Ablegeleistung oder Ablegegeschwindigkeit. Endlich ist nachteilig, daß sich die bekannten Fadenführer leicht durchThis is disadvantageous for several reasons. On the one hand, it cannot be prevented that the thread guide which is passed over the thermoplastic in order to first plasticize it, wear loads because the wire to be laid is usually of considerable hardness and consequently familiarize yourself with the thread guide. This means that the thread guide has to be changed frequently after wear necessary. A repositioning of the thread guide so that the contact surface with the wire after Implementation is processed differently, is not feasible because the Nadelör is on one side of the Thread guide is located and is clearly assigned to the incoming thread. In addition, that bothers the thread guide, but also the heating pin, only represent relatively small dimensions and consequently small ones Form heat storage. This reduces the placement performance or placement speed. Finally it is disadvantageous that the well-known thread guides easily through
