Abstract (en)
[origin: ES8607798A1] A piece of board stock is advanced on a conveying table between a pair of milling units mounted about and below the table. Each milling unit comprises at least one milling tool having a pair of spaced rotary cutting blades and a profiling tool of lesser diameter than these blades sandwiched therebetween. For each pair of blades on the upper milling unit, there is a corresponding pair of blades on the lower milling unit disposed in coplanar relation therewith. Each pair of blades is so dimensioned as to cut at least halfway, but not all the way, through the piece of advanced board stock, and each profiling tool is so dimensioned as to profile the adjacent surface of the board stock. In this manner, a piece of advanced board stock is simultaneously cut into a plurality of slats having opposed profiled edges, and this is done in a single pass.
