By contrast, the Altendorf F 4 made by Hebrock has an optional radius profile scraper which is ideal for reworking edges when needed. A little larger than the F 2 – at 4 meters in length – the F 4 is still a good compromise between saving space and high-performance characteristics.
The F 4's PLC control unit, which can be operated with a 10-inch touch-screen, means that working with the F 4 could not be simpler. With the hot-melt glue changing device accessory, the F 4 edgebander can even cope with PUR processing, too. Unlike the F 2, the F 4 has a surface scraper that comes as standard.
