Abstract
According to the invention, a web of material presenting periodic string parts is provided with garnishing material by forming loops of garnishing material around the net yarn, and subsequently fastening the loops together by applying high frequency energy. This is 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, whereafter the electrodes are again separated to release the string material and garnishing.
Claims2
A method for mutually joining web material exhibiting periodic string parts and garnishing material, comprising the steps of guiding the web material and the garnishing material onto an endless rotating path having provided therein apertures which correspond to the periodicity of the web material, urging the garnishing material down by said string parts to form loops in the garnishing material, said material being urged down beyond pairs of electrodes located at said apertures;
- moving the electrodes of said electrode pairs towards one another;
- applying a high frequency alternating voltage between said electrode pairs, wherein the garnishing material caught between the electrodes is fused together;
- moving apart the electrodes of said electrode pairs;
- and removing the web material together with garnishing material fastened thereto from the endless, rotating path.
