Abstract
To produce wooden laths, boards of optional width are resawn in unplaned condition, whereupon the laths are fed each into one compartment which is defined by splitting knives and within which the laths are subjected to a pressure which is directed against the feed table carrying the laths and under the action of which first the lower side and then the upper side are planed. The machine for resawing the boards and planing the laths has a feed table with a guide edge and sawing means comprising coaxially mounted saw blades adjacent the infeed end of the machine, splitting knives mounted directly after the sawing means and defining compartments each adapted to accommodate a lath, and pressure means above each compartment for applying to the laths a pressure directed against the feed table. Planing means are arranged for working, under the action of said pressure, first the lower side and then the upper side of each lath.
