CA 2218964

It includes a lower tray with rotatory coil holders in "B" sense and a top tray composed of: fixed crown, plate and ring and disk. Said plate and ring define a circumferential track where coil holders run, and there is a sinusoidalgap where thread guides of lower coil holders run, crossing each other with the circumferential track. Coil holders are driven in "A" sense by pullers fixed to the crown and disk and provided with alternative stems guided by shoes or rollers introduced in tracks of the plate and ring; while a stem pulls a coil holder the others avoid the thread guides. When the coil holders of the top and lower trays run a circumferential path, a high number of revolutions is achieved.

L'invention comprend un plateau inférieur avec des porte-bobines pivotant dans le sens «B» et un plateau supérieur composé d'une couronne fixe, d'une plaque et bague et d'un disque. La plaque et bague en question définit une rainure circulaire dans laquelle les bobines tournent. Il existe aussi un espace sinusoïdal où les guide-fils des porte-bobines inférieurs se déplacent en se croisant et en croisant la rainure circulaire. Les porte-bobines sont entraînés dans le sens «A» au moyen de dispositifs de tirage, fixés à la couronne et au disque, sur lesquels sont prévues des tiges alternatives guidées par des sabots ou des cylindres introduits dans les rainures de la plaque et bague; pendant qu'une tige tire un porte-bobine, les autres évitent les guide-fils. Lorsque les porte-bobines des plateaux supérieur et inférieur suivent un trajet circulaire, l'invention parvient à exécuter un nombre élevé de rotations.
