Abstract

UN ELEMENTO TENSOR PARA UN CEDAZO DE HOJA QUE PERMITE TENSAR SIMULTANEAMENTE UNA PLURALIDAD DE HOJAS EN UN CEDAZO DE HOJA, POR EJEMPLO PARA CLASIFICACION DE BRIZNAS DE MADERA. EL ELEMENTO TENSOR DEL CEDAZO DE HOJA INCLUYE UN SOPORTE ARTICULADO (18) QUE PUEDE SER SOPORTADO SOBRE UNA PARTE DE UN MARCO (100), UN SOPORTE DE HOJA DE ACERO PARA RESORTES (14) PARA ENGANCHAR UN CIERRE DE RESORTE A PRESION (42) INSERTADO EN UNA RANURA EN CADA UNA DE LAS HOJAS ENGANCHADAS (22), Y UNA TUERCA LIMITADORA ELASTICA (38) Y PASADOR (36) PARA AJUSTAR Y TENSAR LAS HOJAS (22). LAS HOJAS (22) ESTAN SOPORTADAS EN SU SITIO EN EL EXTREMO OPUESTO DEL MARCO POR UN SOPORTE SIMILAR (12), EL CUAL SIN EMBARGO, ESTA FIJADO MAS QUE ARTICULADO. EL SOPORTE DE LA HOJAS DE ACERO PARA RESORTES (14) ESTA REFORZADA PARA RESISTENCIA ADICIONAL, Y ESTA DOBLADA EN UN ANGULO DE APROXIMADAMENTE 45 GRADOS DONDE ESTA ENGANCHADO EL CIERRE DE RESORTE A PRESION. LAS PROPIAS HOJAS PUEDEN ESTAR PROVISTAS CON UN DETALLE SERRADO (600) EN UN BORDE INFERIOR PARA REDUCIR LA FORMACION DE TIRAS O TROCITOS DE MADERA QUE DE OTRA FORMA SE PRODUCIRIAN. TAMBIEN HAY PROVISTO UN SOPORTE DE DESLIZAMIENTO (400) CON UNA CONFIGURACION A COLA DE MILANO. ESTE SOPORTE DE DESLIZAMIENTO (400) PERMITE ENSAMBLAR UN CEDAZO DE HOJAS DE MARCO DOBLE, MIENTRAS COMPENSA CUALQUIER ERROR DE ANGULO DE FASE ENTRE IRREGULARIDADES (418) PROVISTAS PARA AGITAR LAS BRIZNAS DE MADERA MEDIANTE EL MOVIMIENTO DE LOS CEDAZOS.
