Abstract

Selon la présente invention, lorsque la couture de câble a commencé, une aiguille de couture et un guide de câble sont d'abord abaissés de sorte qu'une partie du câble traversant un orifice dans le guide de câble est perforée par l'aiguille de couture descendante puis abaissée sur le matériau de base de couture. L'aiguille de couture est ensuite actionnée plusieurs fois tandis que le guide de câble abaissé est maintenu à la position la plus basse de telle sorte que ladite partie du câble est cousue en place sur le matériau de base de couture par l'intermédiaire de multiples points. Lorsque la couture du câble est terminée, le guide de câble est relevé, et le câble s'étendant vers le bas à partir du guide de câble est coupé par un dispositif de coupe de câble. Une partie distale du câble coupé pend vers le bas à partir du guide de câble, et est automatiquement cousue en place comme décrit ci-dessus lorsque la couture reprend. Avant la coupure du câble, un crochet de fil d'aiguille est actionné, et le fil est coupé. Par conséquent, il est possible d'effectuer automatiquement une commande appropriée de la couture externe du câble, et de favoriser l'automatisation d'opérations liées à la couture de câble.
