Abstract
The invention relates to a process and an apparatus for the simultaneous throwing of several textile threads delivered continuously, for the purpose of winding them in separate packages on one and the same spindle of a reeling machine. PA1 in a first stage, the threads are arranged according to separate paths defined by separate triangulation guides located upstream of the spindle and by a common point of convergence located downstream, PA1 in a second stage, being kept out of reach of the traversing system, they are grasped selectively by a selection device consisting essentially of a movable elongate element, of the belt type, which is provided with selection guides of different increasing lengths spaced out at regular intervals along the belt and each brought opposite its package zone on the spindle, PA1 in a third stage, they are moved up to a means of picking them upon their supports in order to start the packages. The invention is used for the throwing of threads, particularly in a completely automatic change-over process.
