METHOD AND APPARATUS FOR MANUFACTURING A CORD FOR WELDING FLOOR COVERINGS

摘要

The invention concerns a method and arrangement for manufacturing a wire or cord for welding floor covering, such as linoleum, or an artificial fibre floor covering, which filler wire forms a fixed joint with the separation edges of floor coverings provided with colours and patterns that are placed beside one another, under the influence of thermal processes, all this in such a way that there is hardly any difference in colours and patterns between weld and floor covering. To this aim, according to the invention, a mixture of coloured granules (4) is subjected to a process of mixing, heating (9) and cooling (13) in an arrangement that is designed to this aim.
