摘要： The invention relates to a method for forming a multi-ply fiber web, in which at least part of the forming is done in a twin-wire forming part formed between a wire (10) for the bottom layer of the multi-ply fiber web and a wire (20) for the top layer of the multi-ply fiber web, in which the layers for the multi-ply fiber web are joined and treated layers combined in the twin-wire part. At least part of sizing of the multi-ply fiber web is provided by applying sizing agent in form of foam by a curtain type application device (C10; C20) in between at least two layers of the multi-ply fiber web in forming section of a multi-ply fiber web production line. The invention also relates to a forming section for a multi-ply fiber web comprising at least one twin-wire forming part formed between a wire (10) for the bottom layer of the multi-ply fiber web and a wire (20) for the top layer of the multi-ply fiber web, in which twin-wire part in the layers for the multi-ply fiber web are joined and treated layers combined. The forming section comprises at least a curtain type application device (C10; C20) for applying sizing agent in form of foam by in between at least two layers of the multi-ply fiber web in forming section of a multi-ply fiber web production line.

摘要： The invention relates to a forming section comprising a twin-wire forming unit formed between a lower wire (10) and an upper wire (20), in which first water removal means of the twin-wire forming unit is a forming roll (13) with a wrap angle (13V). In the twin-wire forming unit following the forming roll (13) is a sleeve roll (50) and that run between the forming roll (13) and the sleeve roll (50) is free of vacuumed dewatering i.e. between the forming roll (13) and the sleeve roll (50) no vacuumed dewatering is located.

摘要： The invention relates to a method for the optimization of the properties of a multilayer fiber web (10) in the manufacture of a fiber web (10), in which method the multilayer fiber web (10) is formed by feeding at least two stock suspensions that form a layer (16) of the fiber web (10) to a forming section (50) from two or more headboxes (12) divided into parallel feed zones (18), where those properties of said stock suspensions that affect the strength of the finished fiber web differ from each other, and the basis weight profile of said stock suspensions is adjusted in two or more headboxes (12) by feeding dilution water in zones in the cross direction of the fiber web machine into each stock suspension. In the method, the cross-directional basis weight profile and strength of the formed fiber web (10) are adjusted in the cross direction of the fiber web machine by adjusting the amount of dilution water in zones separately in each stock suspension fed.
The invention also relates to a corresponding system.摘要翻译： 本发明涉及一种用于在纤维幅材（10）的制造多层纤维纸幅（10）的性质的优化的方法，在该方法中多层纤维网（10）是通过将至少两个股票混悬剂FORMED 并形成纤维幅材（10）的层（16），以从两个或更多头盒（12）划分成平行进料区（18）的成形部分（50），其中的说的库存悬浮液，这些属性确实影响的强度 成品纤维网从海誓山盟分化，和所述枪托混悬剂基重分布在两个或更多头盒（12）通过在纤维幅材机的横方向到每个悬浮液在区域供给稀释水来调节。 在该方法中，所形成的纤维网（10）的横方向的单位面积重量分布和强度在纤维幅材机的横向上通过在每个悬浮液进料到单独地调节在区域中的稀释水的量来调节。 因此，本发明涉及一种相应的系统。
