<p>The apparatus 10 comprises a washing chamber 18 and a washing brush 64 on the end of a hose 62 leading to a reservoir 54 for liquid to be applied. The hose 62 is connected to an outlet pipe 58 of the reservoir 54 having a one-way valve which is immersed in liquid in the reservoir and allows movement of the brush 64 to pump liquid from the reservoir 54 to the chamber 18. Liquid supplied to the chamber is collected in a sump 30, the overflow 52 of which feeds the reservoir 54. A filter screen 38 is positioned between the chamber 18 and the sump 30, in which solid material precipitates, allowing liquid to be recycled. The apparatus can be used, for example, for removal of ink from a used screen, removal of stencil material from a used screen or application of a degreasing preparation to a screen prior to use. <IMAGE></p> |
