Description
Verfahren zur Herstellung einer zylindrischen Spule und nach diesem Verfahren hergestellte Spule
Vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung einer zylindrischen Spule sowie auf eine nach diesem Verfahren hergestellte Spule.
Die heute bekannten zylindrischen Spulen werden aus verschiedenen Einzelteilen zusammengesetzt und bestehen teilweise aus metallischen Werkstoffen, welche, einem Druck ausgesetzt, der Ermüdung unterliegen.
Metallische Spulenteile waren bisher notwendig, da zur Aufnahme des infolge des Wickelzugs und der Fadenrelaxation entstehenden Druckes auf den zylindrischen Teil der Spule keine andern Stoffe geeignet waren.
Die vorliegende Erfindung bezweckt, ein Verfahren zur einfacheren Herstellung einer kaum der Ermüdung erliegenden Spule zu schaffen.
Das erfindungsgemässe Verfahren ist gekennzeichnet durch das Spritzen der Spule in einem Stück aus einem glasfaserverstärkten Kunststoff.
Auf der Zeichnung ist ein Ausführungsbeispiel einer nach dem Verfahren gemäss der Erfindung hergestellten zylindrischen Spule dargestellt, und zwar zeigt:
Fig. 1 einen Längsschnitt durch eine Spule
Fig. 2 eine Ansicht der Spule von oben und
Fig. 3 eine Ansicht der Spule von unten.
Die in Fig. 1 dargestellte Spule ist am einen Ende mit einem Dreikant 2 zur Mitnahme auf der Spindel und am andern Ende mit einer konischen Verdickung 3 und einer konischen Rille 4 zur Halterung einer nicht gezeichneten Bezeichnungsscheibe versehen.
PATENTANSPRÜCHE
I. Verfahren zur Herstellung einer zylindrischen Spule, gekennzeichnet durch das Spritzen der Spule in einem Stück aus einem glasfaserverstärkten Kunststoff.
II. Spule, hergestellt nach dem Verfahren gemäss Patentanspruch I.
**WARNUNG** Ende DESC Feld konnte Anfang CLMS uberlappen**.
Process for the manufacture of a cylindrical coil and coil manufactured according to this process
The present invention relates to a method for manufacturing a cylindrical coil and to a coil manufactured according to this method.
The cylindrical coils known today are composed of various individual parts and partly consist of metallic materials which, when exposed to pressure, are subject to fatigue.
Metallic spool parts were previously necessary because no other materials were suitable for absorbing the pressure on the cylindrical part of the spool resulting from the winding tension and the thread relaxation.
It is an object of the present invention to provide a method for manufacturing a hardly-fatigue coil more easily.
The method according to the invention is characterized by the injection molding of the coil in one piece from a glass fiber reinforced plastic.
In the drawing, an embodiment of a cylindrical coil produced according to the method according to the invention is shown, namely shows:
Fig. 1 is a longitudinal section through a coil
Fig. 2 is a view of the coil from above and
3 is a view of the coil from below.
The coil shown in Fig. 1 is provided at one end with a triangular 2 for driving on the spindle and at the other end with a conical thickening 3 and a conical groove 4 for holding a not shown designation disc.
PATENT CLAIMS
I. A method of manufacturing a cylindrical coil, characterized by injection molding the coil in one piece from a glass fiber reinforced plastic.
II. Coil produced by the method according to claim I.
