Method of forming a three-layer board web and a forming section of forming a three-layer board web
The invention relates to a method for forming a three-layer board web, preferably a folding box board (FBB) or a solid bleached (sulfate) board (SBS), in a forming section (300) comprising a multilayer headbox (100) and a forming unit (200). In the method the layers of the three-layer board web are...

| description | The invention relates to a method for forming a three-layer board web, preferably a folding box board (FBB) or a solid bleached (sulfate) board (SBS), in a forming section (300) comprising a multilayer headbox (100) and a forming unit (200). In the method the layers of the three-layer board web are first formed of pulp suspension in the multilayer headbox (100) and fed to only one forming unit (200), which only one forming unit is a gap or combi type twin-wire former, for water removal and for joining the layers of the three-layer board web and water is first removed by a non-pulsating forming shoe (37, 39). The invention also relates to a forming section for forming a three-layer board web, preferably a folding box board (FBB) or a solid bleached (sulfate) board (SBS), which forming section comprises a multilayer headbox (100) and a forming unit (200). The forming unit consist of only one forming unit (200) for water removal and for joining the layers of the three-layer board web and that the one forming unit (200) is a gap or combi type twin-wire former and first water removal means comprises a non-pulsating forming shoe (37, 39). |
