摘要:
An apparatus for applying finishing agents onto a nonwoven web, wherein there is provided a device for pre-bonding of the nonwoven web. There is provided at least one guide surface, over which the pre-bonded nonwoven web is guided. Outlet openings for the finishing agent are provided in the guide surface, so that finishing agent can be applied onto the nonwoven web being guided over the guide surface.

摘要:
An apparatus for applying a treatment liquid to a web moving in a predetermined web-travel direction has an applicator element having a surface extending transverse to the direction and positioned to contact the moving web. The liquid is applied to the surface such that the liquid is transferred to the moving web where the moving web contacts the surface. A shield directly engages a portion of the surface between the web and the surface so that where the shield extends between the moving web and the surface there is generally no transfer of the liquid from the surface to the moving web. Formations on the shield conduct the liquid away from edges of the shield.

An apparatus for applying a liquid to a moving web has an applicator element having a surface extending transverse to the web-travel direction and positioned to contact the moving web. Liquid applied to the surface is transferred to the moving web where the moving web contacts the surface. A support spaced in the web-travel direction from the applicator element has a plurality of guides extending transverse to the web-travel direction, with at least some of the guides overlapping others of the guides. Respective shields slidable in the guides transverse to the direction extend between the web and the surface so that where the shields extend between the moving web and the surface there is generally no transfer of the liquid from the surface to the moving web. Respective adjusters connected to the shields shift same in the respective guides between positions spaced from one another to positions at least partially overlapping one another.
