For operating safety and comfort: Power feeders from the Felder Group The constant feed rate, the high quality rubber rollers and the exact positioning of the workpiece by a power feeder guarantees clean and consistently precise work results for every application. Recommended application: Standard and production work on the spindle moulder or edge sander, planing, trimming and parallel cutting - a power feeder turns your circular saw into a panel sizing saw. On power feeders with an advanced tilting head (Variofeed 3/4, F48), narrow workpieces can be pressed against the fence by turning the head by 90 degrees.
