<p>The system is used for filling in joint gaps between paving or cladding panels, esp. tiles, after laying. A housing unit contains a device for supplying and spreading a plastics grouting substance, extending across the working direction. At an interval behind this there is a power-driven roller for skimming off. The spreader device can also have a driven roller with sheath recesses to hold the grouting material, and full-width media feeding into these: pref. a duct with a valve and nozzles.</p> |
