Leister Tutorial | Zero overlap guide from Leister for Zero Overlap Welding

Whether hot wedge or combi-wedge technology, welding geomembranes presents an additional challenge: the weld seam geometry. This is because in some cases no protruding edges are desired on the surface due to unwelded edge zones, as dirt could accumulate in them. This means that you fully weld the membrane, without any protruding flaps. For example, you can achieve this with an additional extrusion weld seam. However, it is more efficient if you use an automatic welding machine with an appropriate material guide (stop), such as the COMET 700 from Leister with the zero overlap guide. Its material guide automatically creates precise seam geometry.
In this video tutorial you can see how to install the zero overlap guide.
