Method for making fibrous sheets or webs

Abstract

Abstract A METHOD OF MAKING FIBROUS SHEETS OR WEBS CONTAINING A BINDER BY CAUSING A STREAM OF GAS CONTAINING FIBRES TO PASS A GAS PERMEABLE FORMING SURFACE SO AS TO FORM A FIBRE LAYER THEREON AND BONDING TOGETHER THE FIBRES FO THE FIBRE LAYER BY MEANS OF A BINDER. APPARATUS FOR MAKING FIBROUS SHEETS OR WEBS CONTAINING A BINDER WHICH APPARATUS COMPRISES MEANS FOR CREATING A STREAM OF GAS CONTAINING SUSPENDED FIBRES THROUGH A GAS PERMEABLE FORMING SURFACE SO AS TO FORM A FIBRE LAYER THEREON, MEANS FOR APPLYING A BINDER TO THE FIBRES AND MEANS FOR CAUSING THE BINDER TO BIND TOGETHER THE FIBRES OF SAID FIBRE LAYER. PLATE MATERIAL CONSISTING OF A NUMBER OF EMBOSSED FIBERE SHEETS WHICH ARE GLUED TOGETHER AND WHICH ARE FORMED BY CAUSING A STREAM OF GAS CONTAINING SUSPENDED FIBRES TO PASS THROUGH A PERMEABLE FORMING SURFACE SO AS TO FORM A FIBRE LAYER THEREON AND BONDING TOGETHER THE FIBRES OF THE FIBRE LAYER BY MEANS OF A BINDER. FIBROUS SHEET OR WEB CONSISTING OF TWO OUTER LAYERS WHICH HAVE BEEN PREPARED FROM CELLULOSIC FIBRES AND OTHER FIBRES, IF ANY, AND ABINDER BY CAUSING A STREAM OF GAS CONTAINING SUSPENDED FIBRES TO PASS A GAS PERMEABLE FORMING SURFACE SO AS TO FORM A FIBRE LAYER THEREON AND BONDING TOGETHER THE FIBRES OF THE FIBRE LAYER BY MEANS OF SAID BINDER AND AT LEAST ONE INTERMEDIATE CELLULOSIC FIBRE LAYER WHCIH IS BONDED TO THE INNER SIDE OF THE OUTER LAYER (S) BY MEANS OF A BINDER.
