Abstract
A trimmer for a lumber package. The trimmer comprises a reciprocating, retaining carriage to receive the lumber package. A first track. Means reciprocate the retaining carriage along the first track from a loading position through a second position. Cutting means on each side of the track at the second position trim the lumber package. Compressor means are reciprocable at the loading position to compress a lumber package in a direction substantially perpendicular to the first track. Releasable retaining means hold the lumber package in a predetermined, fixed position on the retaining carriage as it moves from the loading position through the second position and is trimmed.
