Title
(EN) LOADING STATION FOR MICRONAIRE TESTING
(FR) STATION DE CHARGEMENT POUR TEST DE MICRONAIRE
Abstract
(EN)
A loading station (100) for forming a fiber mass (112) for micronaire testing. The loading station (100) has a hopper (102) for receiving an unformed fiber mass (112). A forming chamber (107) receives the unformed fiber mass (112) from the hopper (102). The forming chamber (107) includes a non-movable back wall (109) and a non-movable bottom plate (111) with ports (114) formed therein. The ports (114) draw an airflow (113) from the hopper (102) into the forming chamber (107). A selectively movable isolation plate (106) isolates the forming chamber (107) from the hopper (102), and a selectively movable horizontal forming wall (104) horizontally compacts the fiber mass (112) into a desired horizontal cross-section. A selectively movable vertical forming wall (108) vertically compacts the fiber mass (112) into a desired vertical cross-section. A selectively movable plunger (116) presses axially along the shaped fiber mass (112).

La présente invention concerne une station de chargement (100) pour former une masse fibreuse (112) pour un test de micronaire. La station de chargement (100) comprend une trémie (102) pour recevoir une masse fibreuse non formée (112). Une chambre de formation (107) reçoit la masse fibreuse non formée (112) depuis la trémie (102). La chambre de formation (107) comprend une paroi arrière non mobile (109) et une plaque inférieure non mobile (111) à l'intérieur de laquelle des orifices (114) sont formés. Les orifices (114) aspirent un flux d'air (113) depuis la trémie (102) pour l'amener dans la chambre de formation (107). Une plaque d'isolation sélectivement mobile (106) isole la chambre de formation (107) de la trémie (102), et une paroi de formation horizontale sélectivement mobile (104) compacte horizontalement la masse fibreuse (112) dans une section transversale horizontale souhaitée. Une paroi de formation verticale sélectivement mobile (108) compacte verticalement la masse fibreuse (112) dans une section transversale verticale souhaitée. Un piston sélectivement mobile (116) presse axialement le long de la masse fibreuse (112) façonnée.
