Abstract (en)
[origin: EP3382094A1] The invention 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 a sleeve roll (50) for joining layers of the multi-ply fiber web in a sleeve roll nip between the sleeve roll (50) and the wire(10; 20). The invention also 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. In the method the layers of the multi-ply fiber web are joined in a sleeve roll nip between a sleeve roll (50) and the wire (10; 20).
