Description
Verfahren zur Herstellung' von Schwingspulen für elektrodynamische Lautsprecher Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Schwingspulen für elektrodynamische Lautsprecher, bei dem in an sich bekannter Weise die Spulenkörper durch eine teinlagige Hülse aus wendelförmig aufgewickelten Streifen .eines Faserstoffes auf einen Wickeldorn gebildet werden.Process for the production of voice coils for electrodynamic Loudspeaker The invention relates to a method for manufacturing voice coils for electrodynamic loudspeakers, in which the coil formers in a manner known per se through a single-ply sleeve made of helically wound strips of a fibrous material be formed on a winding mandrel.
Die Erfindung besteht darin, daß die Kanten des Streifens bei aneinanderstoßendem Aufwickeln unmittelbar miteinander verklebt werden.The invention is that the edges of the strip when butt against each other Winding are glued together directly.
Durch das Aneinanderstoßen der Kanten wird ein. Verkleben der Kanten gewährleistet, das dann eine gleichmäßige Stärke der Hülse über den ganzen Umfang einschließlich der Stoßkanten ergibt.When the edges meet, a. Gluing the edges ensures that the sleeve has a uniform thickness over the entire circumference including the abutting edges.
Es empfiehlt sich, an den Enden des Spulenträgers Verstärkungsringe vorzusehen, die entweder durch ein weiteres Aufbringen eines spiralig gewickelten Streifens hergestellt sind oder aus einer eingepreßten Verstärkungsrille bestehen.It is advisable to have reinforcement rings at the ends of the coil former provide that either by applying a further spiral wound Strip are made or consist of a pressed-in reinforcing groove.
