CA 2203137

The present invention provides a method and apparatus for forming a pulsed stream of discrete particles of absorbent material. The apparatus comprises a particle metering apparatus (80) for providing a stream (82) of particles having a predetermined mass flow rate, an ejector having an acceleration air nozzle (130) for accelerating the stream of particles, at least one deceleration air nozzle (210), and valving (400) for alternately directing air through the acceleration and deceleration nozzles. The apparatus can be used to form a fibrous web having a predetermined variation in basis weight of absorbent material along the length of the web.

L'invention concerne un procédé et un appareil de formation d'un flux pulsé de particules discrètes de matière absorbante. L'appareil comprend un dispositif (80) de dosage de particules destiné à produire un flux (82) de particules d'un débit massique prédéterminé, un éjecteur présentant une tuyère (130) à air d'accélération destinée à accélérer le flux de particules, au moins une tuyère (210) à air de décélération, et un régulateur de débit (400) destiné à orienter de façon alternée l'air dans les tuyères d'accélération et de décélération. L'appareil peut être utilisé pour former une nappe fibreuse présentant une variation prédéterminée du poids de base de la matière absorbante sur la longueur de ladite nappe.
