Abstract:

In order to determine the geometrical dimensions of the spliced connections of yarn-ends, an algorithm was elaborated using the image analysis technique to determine their dimensions. By applying a Laplace filter, an optimum quality of images with distinguished regions of homogeneity was achieved. The ‘Arithmetic Operations’ procedure was used to determine the geometrical dimensions of the spliced yarn-ends, and the small random error values (below 0.6%) of the average value of measurement results give evidence of the high repeatability of the results. The algorithm of image digitalisation we proposed, together with measurements of the geometry of spliced connections of yarn ends, enabled their identification. The connection of yarn-ends by splicing was realised with the use of the Jointair 4941 splicing-device from Mesdan.
