(57) According to the present invention, a web of material presenting periodic string parts (1), is provided with garnishing material (2) by forming loops of garnishing material around the net yarn, and subsequently fastening the loops together, preferably by applying high frequency energy. This is preferably effected in an automatic machine, in which string parts together with accompanying garnishing (2) are inserted into apertures (140) formed on a drum by means of electrodes (70, 71) which are mutually separated during the process of insertion and which are then clamped together and supplied with high frequency energy, whereafter the electrodes (70, 71) are again separated to release the string material and garnishing. |
