Abstract

1.- Un aparato para formar núcleos absorbentes aplicados por chorros de aire (15,16), que comprenden una primera y segunda rueda formadora de esterilla (1,2), cada una de las ruedas formadoras de esterilla tienen por lo menos un molde (3,4) a lo largo de su superficie periférica, medios para aplicar por chorro de aire (6,10 y 8,12) para suministrar material fibroso arrastrado por aire a los moldes en cada rueda formadora de esterilla, medios de succión (13,14) que mantienen los elementos de núcleo formados en los moldes respectivos durante una parte del trayecto de los moldes sobre las ruedas formadoras de esterilla respectivas y medios para transferir un elemento de núcleo (16) en la segunda rueda formadora de esterilla sobre un elemento de núcleo (15) en la primera rueda formadora de esterilla mientras que el último elemento de núcleo se mantiene en su molde todavía, por lo menos los medios aplicados por chorros de aire (8,12) asociados con la segunda rueda formadora de esterilla comprenden medios para suministrar una mezcla de material fibroso y partículas discretas arrastradas por aire, caracterizado porque los medios (5,9 y 7,11) para aplicar una capa protectora (22,23) al fondo de cada molde (3,4) de por lo menos la segunda rueda formadora de esterilla (2), cuya capa protectora (22,23) tiene la función de proteger el molde de las partículas discretas durante el aplicado por chorros de aire de una mezcla de material fibroso y partículas discretas arrastradas por el aire y para impedir que las partículas discretas se salgan del segundo elemento de núcleo durante y después de la transferencia, las dos ruedas formadoras de esterilla (1,2) forman una tal línea de contacto entre ellas de modo que el segundo elemento de núcleo (16) entrará en contacto con el primer elemento de núcleo (15) antes de la transferencia. 2.- Un aparato de acuerdo con la reivindicación 1, en donde la línea de contacto entre la primera y segunda rueda formadora de esterilla (1,2) es 10 mm a lo máximo. 3.- Un aparato de acuerdo con la reivindicación 2, en donde ambas la primera y segunda rueda formadora de esterilla (1,2) incluye medios para suministrar una mezcla de material fibroso y partículas discretas arrastradas por el aire y medios (5,9 y 7,11) para aplicar una capa protectora (22,23) al fondo de cada molde (3,4) de la primera y segunda rueda formadora de esterilla.1.- An apparatus for forming absorbent cores applied by air jets (15,16), comprising a first and second mat-forming wheel (1,2), each of the mat-forming wheels have at least one mold (3,4) along its peripheral surface, means for applying by air jet (6,10 and 8,12) to supply airborne fibrous material to the molds on each mat-forming wheel, suction means ( 13,14) that maintain the core elements formed in the respective molds during a part of the mold path on the respective mat-forming wheels and means for transferring a core element (16) in the second mat-forming wheel on a core element (15) in the first mat forming wheel while the last core element is still in its mold, at least the means applied by air jets (8,12) associated with the second forming wheel of this The grid comprises means for supplying a mixture of fibrous material and airborne discrete particles, characterized in that the means (5,9 and 7,11) for applying a protective layer (22,23) to the bottom of each mold (3,4) of at least the second mat-forming wheel (2), whose protective layer (22,23) has the function of protecting the mold from discrete particles during the application by air jets of a mixture of fibrous material and entrained discrete particles through the air and to prevent discrete particles from leaving the second core element during and after the transfer, the two mat-forming wheels (1,2) form such a contact line between them so that the second element of core (16) will come into contact with the first core element (15) before transfer. 2. An apparatus according to claim 1, wherein the contact line between the first and second mat-forming wheel (1,2) is 10 mm maximum. 3. An apparatus according to claim 2, wherein both the first and second mat-forming wheel (1,2) includes means for supplying a mixture of fibrous material and discrete particles entrained by air and media (5.9 and 7.11) to apply a protective layer (22,23) to the bottom of each mold (3,4) of the first and second mat-forming wheel.
