Abstract

The three-part spool is for the inking ribbons of typewriters etc., the parts being secured together purely mechanically, without any residual material tension. Each spool flange disc (1) can have a four-part sleeve section formed on it. There are pointed tips (5) on the opposite parts of this section, extending outwards, and engaging in mating recesses (6) in the sleeve forming the core (2). The system is symmetrical about the centreline. The design greatly simplifies assembly, since no tools, or equipment for welding or gluing the parts together, are needed.

Description

Dreiteilige Spule für Maschinenf2rbbänder Three-part spool for machine color tapes

Die Erfindung bezieht sich auf eine dreiteilige Spule für Maschinenfarbbmnder.The invention relates to a three-part spool for machine color ribbons.

Zweck der Erfindung ist eine Vereinfachung der Spulenbewicklung die in der Weise vor sich geht, daß ein flanschloser Spulenkern mit einem Farbband bewickelt wird wonach an den Spulenkern die Spulenflansche befestigt werden.The purpose of the invention is to simplify the winding of the bobbins goes on in such a way that a flangeless bobbin is wound with a ribbon after which the coil flanges are attached to the coil core.

Dreiteilige Spulen für Maschinenfarbbander sind bekannt.Three-piece spools for machine ink ribbons are known.

Bei diesen dreiteiligen Spulen werden die Spulenkerne nach der Bewicklung durch Schweißung, Klebung oder Verformung von Blechlappen mit den Spulenflansche verbunden.With these three-part coils, the coil cores are after winding by welding, gluing or deforming sheet metal tabs with the reel flanges tied together.

Die Befestigung der Spulenflansche an den Spulenkern erfordert bei den bekannten dreiteiligen Spulen Werkzeuge bezw. Vorrichtungen oder auch Schweißmittel und da die Spule für aschinenfarbbnder Massenartikel sind bringt die Vereinfachung des Spulenzusammenbaues technische und wirtschaftliche Vorteile.The attachment of the spool flanges to the spool core requires at the well-known three-part coil tools respectively. Devices or welding means and since the spool for machine color ribbons is a mass-produced item, simplification is brought about of the coil assembly technical and economic advantages.

Der Erfindung lag die Aufgabe zugrunde eine dreiteilige Spule aus Kunststoff zu entwickeln an deren Kern die Spulenflansche ohne Hillmittel befestigt werden können.The invention was based on the object of a three-part coil To develop plastic at the core of which the spool flanges are attached without Hillmittel can be.

Die Lösun der Auf gabe besteht in der erfinderische Maßnahme der Ausbildung von Segmenten an den Innenseiten der Spulenflansche die mit leichtem Druck in entsprechenden Ausnehmungen des Spulenkerns einrasten.The solution to the task consists in the inventive measure of training of segments on the insides of the spool flanges which with light pressure in corresponding Engage the recesses in the coil core.

Die erfindungsgem.ße dreiteilige Spule ist auf der Zeichnung mit den Abbildungen 1 bis 5 dargestellt.The three-part spool according to the invention is shown in the drawing with Figures 1 to 5 shown.

Abbildung 1 zeigt einen Schnitt durch den linken Spulenflansch, die Abbildung 2 einen Schnitt durch den Spulenkern und die Abbildung 3 einen Schnitt durch den rechten Spulenflansch. Die Abbildung 4 zeigt einen Schnitt durch die zusammen gesetzte Spule. Abbildung 5 zeigt eine Sicht auf die Innenseite des Spulenflansches (1) Die Spulenflanschscheibe (1) ist einseitig mit einer vi er get eilt en Hülse versehen wovon zwei sich gegeniiberliegenden Hülsenteile () nach außen übergreifenden Spitzkanten (5) aufweisen. Die restlichen zwei Hiilsenteile (7) sind glatt. In dem Spulenkern (2) befinden sich zwei Ausbrüche (6) die so bemaßt sind, daß die übergreifenden Spitzkanten (5) genau eingesprengt werden können wie Abbildung 4 zeigt.Die Bohrung (3) dient zur Aufnahme der Spulenachse.Figure 1 shows a section through the left spool flange, the Figure 2 shows a section through the coil core and Figure 3 shows a section through the right spool flange. Figure 4 shows a section through the together set coil. Figure 5 shows a view of the inside of the spool flange (1) The spool flange washer (1) has a vi he get on one side hurriedly provided a sleeve of which two opposite sleeve parts () outwards have overlapping pointed edges (5). The remaining two shell parts (7) are smooth. In the coil core (2) there are two cutouts (6) which are dimensioned so that that the overlapping pointed edges (5) can be sprinkled exactly as shown 4 shows. The hole (3) is used to accommodate the spool axis.

it der erfindungsgemäßen dreiteiligen Spule für Maschinenfarbbänder wird der Zweck der Erfindung erreicht indem es möglich ist die Spulenflansche durch leichten Andruck fest mit dem Spulenkern zu verbinden; L e e r s e i t eit the three-part reel according to the invention for machine ink ribbons the purpose of the invention is achieved in that it is possible through the spool flanges light pressure to connect firmly to the coil core; L e r s e i t e
