Abstract

EL INVENTO ESTA DIRIGIDO A UNA MAQUINA PAPELERA EN LA QUE LA HOJA DE PAPEL HUMEDA ES SOPORTADA POR LA SECCION DE PRENSA SINTIENDO COMO ES TRANSFERIDA DESDE LA SECCION DE PRENSA ALA SECCION DE SECADO DE LA MAQUINA, POR ELLO PREVENIR HUNDIMIENTO Y POSIBLES ROTURAS DE LA HOJA. ACORDE A ESTE INVENTO, EL FIELTRO ES MONTADO PARA QUE PASEN Y VIAJEN SIN FIN ALREDEDOR DE AL MENOS UN PRIMERO DE DICHOS RODILLOS SECADORES, DICHO FIELTRO QUE NO ESTA SOPORTADO SOBRE UNA DISTANCIA SUSTANCIAL SE EXTIENDE ENTRE DICHOS RODILLOS, PRENSORES Y DICHO PRIMER RODILLO SECADOR DICHA HOJA ES LLEVADA EN LA SUPERFICIE SUPERIOR DEL FIELTRO COMO DICHO FIELTRO VIAJA A TRAVES DE DICHA DISTANCIA. COMO LA HOJA DE PAPEL HUMEDA ES SOPORTADA EN EL ESTIRADO, EL HUNDIMIENTO Y LA POSIBLE RUPTURA DE LA HOJA SON PREVENIDOS EN ESTE AREA. COMO SU TENDENCIA PARA LA RUPTURA ES MINIMIZADA, EL PRODUCTO PERDIDO ES MINIMIZADO Y EL TIEMPO DE LA MAQUINA ES CORRESPONDIENTEMENTE DISMINUIDO.THE INVENTION IS DIRECTED TO A PAPER MACHINE IN WHICH THE WET PAPER SHEET IS SUPPORTED BY THE PRESS SECTION FEELING HOW IT IS TRANSFERRED FROM THE PRESS SECTION TO THE DRYING SECTION OF THE MACHINE, THEREFORE PREVENTING COLLAPSE AND POSSIBLE BREAKAGE OF THE SHEET . ACCORDING TO THIS INVENTION, THE FELT IS ASSEMBLED FOR THEM TO PASS AND TRAVEL WITHOUT END AROUND AT LEAST ONE OF SUCH DRYING ROLLERS, SUCH A FELT THAT IS NOT SUPPORTED ON A SUBSTANTIAL DISTANCE, SENSITIVE DRYERS AND DICH LEAF IS CARRIED ON THE UPPER SURFACE OF FELT AS SUCH FELT TRAVELS THROUGH SUCH DISTANCE. AS THE WET PAPER SHEET IS SUPPORTED ON THE STRETCH, SINKING AND POSSIBLE BREAKING OF THE SHEET ARE PREVENTED IN THIS AREA. AS THEIR TREND FOR BREAKAGE IS MINIMIZED, THE LOST PRODUCT IS MINIMIZED AND THE TIME OF THE MACHINE IS CORRESPONDINGLY DECREASED.
