ABSTRACT:
A blade planer utilizes a centering mechanism to locate the centerline of lumber on the datum plane intermediate a pair of offset blade planer heads. The centering mechanism includes a plurality of opposed shoes which are hydraulically or mechanically linked such that displacement of one shoe from a predetermined reference yields a simultaneous equal displacement in the opposing shoe. Biased return to the reference ensures that the shoes are always centered on the datum plane regardless of the separation of the blade planer heads.
