Abstract

SE DESCRIBE UN CILINDRO DE PAPEL EXPANDIDO FORMADO DE UNA ESPIRAL COMO UN RELLENO DE VACIO. SE PROPORCIONA UN SISTEMA DE DISTRIBUCION PARA DISTRIBUCION AUTOMATICA Y MANUAL DEL PAPEL EXTENDIDO DESDE UN ROLLO BOBINADO CONTINUO, NO EXTENDIDO DE UN MATERIAL DE HOJA EXTENSIBLE. EL MATERIAL DE COMPRESION FORMADO POR EL MANDRIL DE EXTENSION PUEDE UTILIZARSE COMO UNA HOJA EXTENDIDA ALREDEDOR DE UN ARTICULO O COMO UN RELLENO DE VACIO, O PUEDE FORMARSE EN CILINDROS EN ESPIRAL PARA USO COMO RELLENO DE VACIO. EL SISTEMA DE DISTRIBUCION MANUAL INCLUYE UN ELEMENTO DE SOPORTE QUE SOPORTA UN ROLLO DE ALIMENTACION DE BOBINADO. UN DISPOSITIVO DE RETENCION DISMINUYE LA VELOCIDAD DE LA DISTRIBUCION LIBRE DEL ROLLO DE ALIMENTACION DE LA BOBINA DE MATERIAL DE HOJA NO EXTENDIDO, DE MODO QUE EL MATERIAL DE HOJA SE EXTIENDA MIENTRAS SE ESTE ESTIRANDO, BAJO TENSION DESDE EL ROLLO DE ALIMENTACION. UN SISTEMA AUTOMATICO UTILIZA RODILLOS EXPANSORES PARA EXTENDER EL PAPEL CORTADO Y PUEDE COORDINARSE CON UN APARATO QUE CORTA Y FORMA LOS CILINDROS EN ESPIRAL.AN EXPANDED PAPER CYLINDER FORMED OF A SPIRAL IS DESCRIBED AS A VACUUM FILLING. A DISTRIBUTION SYSTEM IS PROVIDED FOR AUTOMATIC AND MANUAL DISTRIBUTION OF PAPER STRETCHED FROM A CONTINUOUS ROLLED ROLL, NOT STRETCHED FROM A STRETCHABLE SHEET MATERIAL. THE COMPRESSION MATERIAL FORMED BY THE EXTENSION CHUCK MAY BE USED AS AN EXTENDED SHEET AROUND AN ARTICLE OR AS A VACUUM FILLING, OR MAY BE FORMED IN SPIRAL CYLINDERS FOR USE AS A VACUUM FILLING. THE MANUAL DISTRIBUTION SYSTEM INCLUDES A SUPPORT ELEMENT THAT SUPPORTS A WINDING FEED ROLL. A RETENTION DEVICE DECREASES THE SPEED OF THE FREE DISTRIBUTION OF THE FEED ROLL OF THE COIL OF LEAF MATERIAL NOT EXTENDED, SO THAT THE LEAF MATERIAL IS EXTENDED WHILE IT IS STRETCHING, LOW VOLTAGE FROM THE ROLL. AN AUTOMATIC SYSTEM USES EXPANDER ROLLERS TO EXTEND THE CUT PAPER AND CAN BE COORDINATED WITH A DEVICE THAT CUTS AND FORMS THE SPIRAL CYLINDERS.
