Abstract

LA PRESENTE INVENCION SE REFIERE A UN APARATO PARA TRATAR SUSPENSION DE FIBRAS. SEGUN LA PRESENTE INVENCION EL APARATO ESTA ESPECIALMENTE ADECUADO PARA SELECCION DE PULPAS Y TAMBIEN PARA ESPESAMIENTO. MAS PRECISAMENTE, EL APARATO SE REFIERE A LA CONSTRUCCION DE UN MIEMBRO DE PULSO DE LA PANTALLA O ESPESADOR QUE SE HA USADO. ES CARACTERISTICO DE TODOS LOS MIEMBROS PULSO SEGUN EL ARTE ANTERIOR QUE CUANDO LA CAPACIDAD DEL APARATO DE SELECCION SE INCREMENTA, POR EJEMPLO, A TRAVES DEL USO DE DIFERENCIAS DE PRESION MAYORES O DE LIMPIEZA DEL ACEPTADO SE INCREMENTA MEDIANTE EL DECRECIMIENTO DE LA TALLA DE LAS PERFORACIONES O RANURAS, ESTO DA COMO RESULTADO UNA SITUACION EN LA QUE EL CILINDRO DE PANTALLA TIENDE A OBSTRUIRSE. EL PROBLEMA ES POR ELLO EL MANTENIMIENTO DEL CILINDRO DE PANTALLA LIMPIO, LO QUE ES UNA PRECONDICION PARA OPTIMIZAR OTRAS CARACTERISTICAS PARTICULARES EN LA SELECCION. LA PRESENTE INVENCION SE REFIERE A UN MIEMBRO DE PULSO (P) DEL APARATO DE SELECCION, QUE SE CARACTERIZA EN QUELA SUPERFICIE DE PANTALLA ESTA SUJETA POR ESTO CON MIEMBROS (60) A UN PULSO QUE LIMPIA LA SUPERFICIE DE LA PANTALLA SIN TENER LA OPORTUNIDAD DE PERMITIR AL EFECTO DE PRESION "ESCAPE" PASAR EL AREA QUE HA SIDO LIMPIADA. SEGUN LA PRESENTE INVENCION TAMBIEN ES TIPICO DEL MIEMBRO DE PULSO QUE CUANTO MAYOR SEA LA CONSISTENCIA DE ENTRETEJIDO DE LA FIBRA O CUANTO PEOR SEA LA OBSTRUCCION DE LA SUPERFICIE DE LA PANTALLA MAS FUERTE ES EL PULSO QUE LIMPIA LA SUPERFICIE DE LA PANTALLA.
