Sanding line To maximize the productivity of the line, feeding and stacking stations can be equipped with accumulator arms to facilitate continuous operation during stack changes. The transfer carriage at the end of the line can transfer stacks to intermediate storage. • Aligning conveyor adjusts the stack according to its center axis and conveys it to sanding machine. • Aligning fence is positioned automatically according to panel width. • The conveyor introduces the panels into sanding machine according to a pre-set speed gap.

Sanding line Grading can be carried out visually by line operator or automatically by a camera-based grading system. The panel can easily be taken out to the inspection station beside the sanding line for closer inspection. To avoid unnecessary stacking and storing of the A-graded products, in most cases the cut-to-size sawing line can be directly connected to the sanding line, where the panels are cut to final size directly after sanding.
