Abstract

"APARELHO PARA PRODUZIR UM MATERIAL ENTRELAçADO A SECO". A invenção se relaciona a um tubo de tela a ser usado na formação a seco de um material entrelaçado para distribuir um material fibroso soprado dentro do tubo de tela através de uma camisa (2) do tubo sobre um transportador que se move sob o tubo. Faz-se o material fibroso provido dentro do tubo se mover, por exemplo, por meio de um rolo de espigas colocado dentro do tubo de modo que o movimento de material fibroso tenha ambos componentes, radial e tangencial, em relação à camisa (2) do tubo de tela. A camisa compreende em sua superfície interna ranhuras perfiladas (8) na direção axial do tubo. A borda (8a) da ranhura perfilada se localiza a jusante em relação ao componente tangente do fluxo de fibras. A borda a montante (8b) da ranhura se localiza a jusante em relação ao componente tangencial do fluxo de fibras. Os fundos das ranhuras perfiladas compreendem furos ou fendas (9) através das quais as fibras são descarregadas a partir do tubo de tela. Na invenção, a borda a jusante (8a) das ranhuras perfiladas se encontra em um ângulo mais agudo em relação ao componente tangencial do material fibroso que a borda a montante (8b)."APPLIANCE TO PRODUCE A MATERIAL INTERLATED TO DRY". The invention relates to a screen tube to be used in the dry formation of an interlaced material to distribute a fibrous material blown into the screen tube through a tube jacket (2) on a conveyor that moves under the tube. The fibrous material provided inside the tube is made to move, for example, by means of a spike roll placed inside the tube so that the movement of fibrous material has both components, radial and tangential, in relation to the jacket (2) the screen tube. The jacket comprises profiled grooves (8) on the inner surface in the axial direction of the tube. The edge (8a) of the profiled groove is located downstream from the tangent component of the fiber flow. The upstream edge (8b) of the groove is located downstream from the tangential component of the fiber flow. The bottoms of the profiled grooves comprise holes or slits (9) through which the fibers are discharged from the screen tube. In the invention, the downstream edge (8a) of the profiled grooves is at a more acute angle to the tangential component of the fibrous material than the upstream edge (8b).
