The KombyPass has two workpiece section settings available: one by photocell that detects the incoming workpiece activating the descent of the upper slide that, by leaning on the workpiece, triggers the feed movement. The second by electronic positioning from touch-screen unit. Just after the bottom working unit selected (brushes unit or sanding unit) starts working on the work-piece lower side. It’s possible to select both working units, which will work simultaneously on the same pass. When the second photocell detects the exit of the work-piece the upper slide goes up while the brushes stop or/and blower pneumatic pad depressurizes.
