Abstract (en)
[origin: EP2202354A1] The process comprises rotating a movable support porous surface comprising impermeable zones (12) in a bath of fibrous solution and causing agglutination of the fibers on the support surface, connecting a band (1) comprising exposed parts and bridge parts to an end of the support surface so that the exposed parts are opposite to the sealed areas of the support surface, and continuously agglutinating the fibers so that the fibers are accumulated on bridge parts and around the exposed parts. The impermeable zones are formed on a web using an adhesive product. The process comprises rotating a movable support porous surface comprising impermeable zones (12) in a bath of fibrous solution and causing agglutination of the fibers on the support surface, connecting a band (1) comprising exposed parts and bridge parts to an end of the support surface so that the exposed parts are opposite to the sealed areas of the support surface, and continuously agglutinating the fibers so that the fibers are accumulated on bridge parts and around the exposed parts. The impermeable zones are formed on a web using an adhesive product. The band comprises portions forming narrow parts of the bridge, and large portions forming the exposed parts.
