Abstract
A device dewaters a wet-laid non-woven web formed from a fibrous suspension. The device has a multiplicity of dewatering strips which are disposed so as to be mutually spaced apart. Mutually neighboring dewatering strips conjointly delimit a dewatering gap for discharging liquid from the fibrous suspensions. The device further has at least three format slides which along the longitudinal direction of the respective dewatering gap are disposed or disposable so as to be distributed relative to one another and which partially obscure the dewatering gap in such a manner that any discharging of the liquid by way of the obscured part of the dewatering gap is prevented.
