Abstract (en)
A method of forming cotton wool articles, e.g. cotton wool balls, pleats or pads, comprises forming the articles from a web derived from a carding machine (1) the input to which consists of discreet lengths of coloured cotton wool lap (3,4,5) fed to the carding machine in an end-to-end sequence. The effect of the carding machine is to blur the changes in colour which occur as each successive lap is delivered to the carding machine with the result that the final product exhibits a gradual transition in colour. The resultant product is aesthetically more pleasing than prior art multi-coloured cotton wool products which exhibit sudden transitions in colour and enables multi-coloured products to be manufactured continuously on a single machine line. <IMAGE>
