ABSTRACT OF THE DISCLOSURE A finger jointing machine in which timber is fed on a horizontal support table and is clamped against this table and against a vertical guide fence adjacent the table. The timber is clamped with the rear end of one piece of timber spaced from the front end of a second piece of timber at a defined spacing. A cutting and gluing unit is movable vertically through the space and carries two rotatable cutters, rotatable about horizontal axes, each cutter having axially spaced teeth, the teeth of one cutter being axially spaced from those of the other by half the spacing between the teeth. The cutters are caused to rotate in opposite directions so that the teeth of one cutter engaging the rear end of the one piece of timber and the teeth of the other cutter engaging the front end of the other piece of timber are both moving upwardly as the cutting and gluing unit is caused to move upwardly. The cutting and gluing unit also includes two ribbed gluing rollers arranged one below each of the cutters, the ribs of the gluing rollers being disposed directly below the teeth of the cutter thereabove, so that they pass through the groove formed by the respective cutter thereabove. The cutting is effected by vertical upward movement of the cutters and support members are arranged which themselves have the shape of the fingers -1- and prevent the wood from breaking out as the cutters pass up to the top surface. These cutters are retracted immediately after the cutters have gone by so that glue is not deposited thereon. - 1a -
