摘要：
A method for the welding of plastic materials in the form of webs, films or the like by means of a heating wedge, welding being carried out without the use of a second pressure roller below the welded material webs. For this purpose, the heating wedge is placed onto the lower material web and is moved over the latter under pressure. The pressure is generated via a holding-down device which has a holding-down roller and which presses onto the upper material web and onto the heating wedge. A floating mounting for the heating wedge compensates for slight unevennesses on the lower material web.
