Abstract: Described is a drain board (100) for a device for applying a liquid film to a web (8) of textile material. The drain board (100) comprises a support (1), on which a strip (10), which constitutes the draining surface (A) and is made of planar material is held flat, for example by magnets (3), by means of a vacuum or by a contact adhesive.
