Abstract
According to the present 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, 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, whereafter the electrodes are again separated to release the string material and garnishing.
Claims4
Apparatus for fastening a web material having periodic string parts, comprising means for advancing the web material in an ordered, outspread fashion, means for advancing garnishing material, and means for attaching garnishing material to said string parts of said web material, and in which the attachment means include an endless, rotating path on which there are disposed periodically arranged apertures for receiving said string parts and garnishing material entrained therewith, and pairs of electrodes including means for moving said pairs of electrodes towards and away frown one another and means for supplying high frequency energy to said electrodes, each of said electrodes being located on a respective side of said apertures and functioning to bring together and to mutually secure garnishing material which wraps around said string parts as they enter said apertures.
