  • Patent number: 4422488
    Abstract: The machine described in this disclosure serves to produce pairs of drawer sides from a panel, the thickness of which is slightly more than twice the thickness of one drawer-side; a first arrangement of saws cuts the panel to a predetermined drawer-side height; while a second arrangement of saws cuts off the panels to a predetermined drawer-side length; by means of conveyors, the panels are then passed to a band-saw which slits each panel, through its thickness, into two boards of substantially equal dimensions; two tables each receive a board laid flat, the lower surface of each board being planed by a series of cutters, the sides being machined by a second series of cutters, and the upper surface being planed and grooved by a third series of cutters; the boards are then brought together on a machining table where horizontal and vertical dovetailing heads form a male dove-tail at the end of the drawer-side and a female dove-tail on the upper surface of the drawer-side.
