  • Patent number: 4130150
    Abstract: 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.
