Abstract

Le dispositif de sélection (7) fixé au chariot (5) de la machine sélectionne directement les clavettes (3) ou les aiguilles. La sélection est opérée au moyen de rampes magnétiques opposées dans lesquelles est formée une zone magnétiquement neutre où opère un électroaimant de sélection. En cas de défaillance du courant dans l'électroaimant les aiguilles restent hors travail. Un tel dispositif autorise des fréquences de sélection très élevées en évitant tout risque de dommages dus à une défaillance du dispositif. The selection device (7) fixed to the carriage (5) of the machine directly selects the keys (3) or the needles. The selection is made by means of opposite magnetic ramps in which a magnetically neutral zone is formed where a selection electromagnet operates. In the event of a current failure in the electromagnet the needles remain out of work. Such a device allows very high selection frequencies while avoiding any risk of damage due to a failure of the device.
