Abstract
In a method and device for applying a thread to a moving substrate, a thread is continuously dispensed to a pick-up point adjacent to the point of contact of two rotating wheels ( ) that are inclined towards each other. The peripheries of the wheels have fingers ( ) which hook the thread and move it to one side or the other as the wheels rotate, and then deposit the thread extended between the fingers 180° from the pick-up point. Long spaces between the fingers ( ) on one wheel or the other make it possible to lay the thread longitudinally ( ) or in a long diagonal line instead of merely in a lateral zigzag pattern. The method and device may be used to make an absorbent article, such as a diaper.
