The Trimming unit and the profiling of the edgeband can leave fine surface irregularities on the edge surface (knife blows). This visual 'error' is removed with the Profile scraper.
Construction and Operation
A knife holder with vertical and horizontal tracing rollers is mounted afloat for each side (bottom/top) of the edge. These knife holders are equipped with profiled knives. A support with Digital counters brings the knives in the right position to the workpiece edge.
With the help of Tracing rollers the knife holder guide the scraper over the Workpiece edges so that a fine tension is lifted,comparable with the Finishing Planing. This removes the knife blows.
Blow jets feed the plastic waste to the dust extraction. Without this Nozzles would be a higher risk for getting waste between workpiece and tracing rollers, thereby Scraper would be raised shortly.
