Abstract:
A method of repairing or refurbishing a litter screen comprising a support frame with a surface, a surrounding flange and a worn or damaged wirecloth, comprising the steps of:(a) stripping worn or damaged wirecloth from the surface of the frame; (b) inserting the frame in a mould and injecting fresh polymer material into the mould so as to reform ridges on the surface of the frame corresponding to those which existed when the frame was first manufactured, before fresh wirecloth is applied thereto, (c) placing fresh wirecloth over the frame and tensioning it as appropriate; (d) applying heat so as to soften the frame surface over which the wirecloth is stretched, so that the latter can penetrate softened plastics material of the frame surface and become embedded therein; (e) allowing the frame and its associated fresh wirecloth to cool; (f) removing tensioning applied; and (g) trimming back exposed edges of the wirecloth back to the surrounding flange.
