Dependent claims

A jointing attachment for a thickness planer having a rotatable top cutter head and a rotatable bottom cutter head mounted on a movable carriage having an outboard side provided with a laterally displaceable grinding element and an inboard side wherein both of the cutter heads are provided with a plurality of inserted tooth carbide heads and the jointing attachment comprises

an auxiliary motor member having an output shaft provided with at least one pulley reel,
a drive belt unit including a drive belt member having one end adapted to be operatively connected to a selected one of said top and bottom cutter heads wherein the other end of the drive belt member is adapted to be operatively connected to said at least one pulley reel;
and,
means for mounting said auxiliary motor member in a free floating fashion relative to the thickness planer, whereby the drive belt member is used to support a portion of the auxiliary motor member relative to the inboard side of the movable carriage.

A method of jointing inserted tooth carbide heads on the top and bottom rotary cutter heads of a thickness planer wherein the thickness planer is provided with a laterally displaceable carriage that rotatably suspends the bottom cutter head and which is provided with a laterally displaceable grinding element including the steps of:

suspending an auxiliary motor member in a pivoted fashion from a first selected one of the rotary cutter heads and a portion of the thickness planer by a drive belt member that is operatively connected on one end to a selected portion of the selected one of the rotary cutter heads and operativley connected on the other end to a pulley reel disposed on the output shaft of the auxiliary motor member;
actuating the motor member to provide a counterclockwise rotation to the selected cutter head via the drive belt member;
and,
bringing the laterally displaceable grinding element into sequential engagement with selected ones of the inserted tooth carbide heads of the selected rotary cutter heads.
