PCT No. PCT/SE90/00719 Sec. 371 Date Jun. 28, 1991 Sec. 102(e) Date Jun. 28, 1991 PCT Filed Nov. 6, 1990 PCT Pub. No. WO91/06822 PCT Pub. Date May 16, 1991.According to the invention, a web of material presenting periodic string Darts is provided with garnishing material 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 are inserted into apertures formed on a drum by means of electrodes which are mutually separated during the process of insertion and which are then clamped together and supplied with high frequency energy, where after the electrodes are again separated to release the string material and garnishing.
