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. The liquid is poured out at point (4) on to the draining surface (A); it flows down and falls off the lower edge (6) of the strip (10) in a falling film (7) or veil on to the fabric web (8). As a result of the magnetic retention, the strip cannot be replaced (FIG. 1).
Claims18
A drain board for a device applying a liquid film to a web of textile material, said drain board extending obliquely over the web and tilting down toward the web of textile material in a vertical longitudinal plane, said drain board comprising:
- a support having a flat supporting surface and a lower edge extending horizontally above the web;
- and
- an intrinsically stable, flat, detachable strip connected to said support and forming a draining surface with the lower edge of the support, said strip having a bearing surface area disposed on said supporting surface of the support, said bearing-surface area being coupled to said supporting surface by forces acting in a direction substantially perpendicular to the plane of said strip such that said supporting surface is free of bore holes, whereby the liquid can be applied to an upper area of the drain board so that the liquid runs down over the draining surface and falls onto the web from the lower edge thereof as a substantially uniform film.
