Abstract: front page image
(EN)The invention relates to a device and a method for automatically stabilising the thread tension in sewing machines. A tension means (7) tensions an upper thread (15) in a portion (9) of the upper thread (15) which is guided to a needle (8). In accordance with the invention the tension means (7) comprises a pneumatic spring retractor (3), which additionally tensions the portion (9) of the upper thread (15) guided to the needle (8). A sewing machine according to the invention, which comprises the device or is designed to carry out the method, is able to produce high-quality seams, even with changing sewing speeds and with different materials.
(FR)L'invention concerne un dispositif et un procédé de stabilisation automatique de la tension du fil dans des machines à coudre. Selon l'invention, le moyen de tension (7) comprend un rétracteur (3) à ressort pneumatique, qui augmente la tension de la partie (9) du fil supérieur (15) guidé vers l'aiguille (8). La machine à coudre selon l'invention, qui comprend ce dispositif ou est conçue pour mettre en oeuvre le procédé, est capable de produire des coutures de qualité supérieure, même à des vitesses de couture variables et avec des matières différentes.
