Abstract

LA INVENCION SE REFIERE A LA MANUFACTURACION DE PALOS O TRONCOS EN FORMA DE VARILLA ENROLLABLE A PARTIR DE FIBRAS CONTINUAS HILADAS MEDIANTE DESCARGA ALTAMENTE ORIENTADAS. LAS FIBRAS SON CONDUCIDAS DESDE LA SALIDA DE UN DISPOSITIVO HILADOR (91) A TRAVES DE UN TUNEL (92) Y AL INTERIOR DE UNA BOQUILLA DIVERGENTE DE DOS ETAPAS (120) PARA REDUCIR LA VELOCIDAD DE LAS FIBRA PARA UNA RECOGIDA ORGANIZADA EN LA SECCION DE RECOGIDA (150). LA INVENCION INCLUYE ADEMAS UNA VEJIGA INFLABLE (185) Y UNA SECCION DE DESCARGA (181) PARA INICIAR LA FORMACION DEL TRONCO Y UNA PANTALLA EN FORMA DE MALLA (155) EN LA SECCION DE RECOGIDA (150) PARA REDUCIR LA OCURRENCIA DE EXPLOSIONES DE FIBRAS A TRAVES DE LOS PUERTOS DE DESCARGA DE GAS (152).THE INVENTION IS REFERRED TO THE MANUFACTURING OF STICKS OR TRUNKS IN THE FORM OF A ROLLABLE ROD FROM HIGHLY DIRECTED SPINNING FIBERS. THE FIBERS ARE CONDUCTED FROM THE EXIT OF A SPINNING DEVICE (91) THROUGH A TUNNEL (92) AND INSIDE A DIVERGENT NOZZLE OF TWO STAGES (120) TO REDUCE THE SPEED OF THE FIBERS FOR AN ORGANIZED COLLECTION IN THE SECTION OF COLLECTION (150). THE INVENTION FURTHER INCLUDES AN INFLATABLE BLADDER (185) AND A DISCHARGE SECTION (181) TO INITIATE TRUNK FORMATION AND A MESH-SHAPED SCREEN (155) IN THE COLLECTION SECTION (150) TO REDUCE THE OCCURRENCE OF FIBER EXPLOSIONS THROUGH THE GAS DISCHARGE PORTS (152).
