Abstract

A lug loader includes a first shaft rotatably mounted transversely across a board flow path, wherein a board in the board flow path is aligned transversely across the board flow path. The board translates in a downstream direction on a board infeed transfer from an upstream position. A board supporting structure such as a disc is rigidly mounted to the first shaft so as to rotate with rotation of the first shaft. The board supporting structure has a shoe mounting surface extending generally orthogonally from the first shaft. The board supporting structure also has a radially outer-most rim, radially outer-most relative to the first shaft. The rim is generally circular and generally circumferentially contiguous so as to form a board supporting surface around the rim. An elongate shoe has first and second ends. A board supporting heel is mounted on the shoe. The shoe is pivotally mounted at the first end of the shoe to the shoe mounting surface. A cam follower is mounted to the shoe at generally the second end of the shoe so as to protrude from the shoe away from the shoe mounting surface.
