Abstract
A thickness planer comprising a main body which includes a base structure and a support structure, a cutter carriage adapted to have a cutter assembly operatively mounted thereto, when in an installed position, and a separate roller carriage adapted to have at least one roller assembly operatively mounted thereto, when in an installed position. The cutter carriage and the roller carriage are each mounted to the support structure and arranged so that when the thickness planer is in an in use configuration, the cutter carriage and roller carriage are substantially isolated or separated from one another. The arrangement inhibits or substantially reduces forces generated during use being transferred from the roller carriage to the cutter carriage.
Claims27
A thickness planer comprising a main body which includes a base structure and a support structure, a cutter carriage configured to have a cutter assembly operatively mounted thereto, when in an installed position, and a roller carriage configured to have at least one roller assembly operatively mounted thereto, when in an installed position the roller assembly including at least one roller, the cutter carriage and the roller carriage each being mounted to the support structure above and in spaced relation from the base structure and arranged so that when the thickness planer is in an in use configuration, the cutter carriage and roller carriage are substantially isolated or separated from one another.

A roller assembly for use in a thickness planer, the roller assembly comprising a roller support frame mounted for pivotal movement about a pivot axis (P-P), two rollers each having a rotation axis, the rollers being mounted to the support frame, the roller rotation axes being substantially parallel to the pivot axis (P-P) with one roller being located to one side of the pivot axis (P-P) and the other roller being located to the other side of the pivot axis (P-P), the roller assembly optionally including any one or combination of:
- the support frame comprising first and second frame sections each being mounted for pivotal movement about the pivot axis (P-P) and in spaced apart relation with respect to one another, the rollers having ends which are operatively connected to respective ones of the first and second frame sections;
- the ends of the rollers being operatively mounted to the frame sections so as to be laterally movable with respect to the roller axis and the pivot axes in a lateral direction towards an operative position;
- and
- a pressure applicator being included for urging the rollers in the lateral direction towards the operative position, wherein the pressure applicator optionally comprises springs associated with each end of the rollers for biasing the rollers in the lateral direction towards the operating position.
34-37. (canceled)
An airstream flow control apparatus for a thickness planer, the thickness planer including a base structure, a support structure and a cutter carriage, the airstream flow control apparatus being operatively mounted to the cutter carriage when installed and comprising a downdraft system for directing a flow of air from the cutter carriage towards the base structure and an updraft system for drawing air away from the support structure.
