Abstract
The board positioning device of the present invention is for optimally longitudinally positioning a board for trimming. The board is translated from an upstream position to a downstream position in a first direction towards the trimming saws. The board translates at a translation speed on a board translating device such as a lugged transfer chain. The board while translating in the first direction, is aligned longitudinally, that is, along its length, in a second direction perpendicular to the first direction so as to position the board relative to the saws. The board is urged by board ending means, such as ending rolls, in the second direction against a corresponding board positioning member, such as a shaft mounted paddle, on the board positioning device. In the preferred embodiment, the first and second directions lie in a generally horizontal plane. The selectively actuable first flexible guide member is rigidly mounted at an upstream end thereof to, or adjacent to, a downstream end of a rigid fence extending parallel to the first direction. The selectively actuable flexible guide member may be selectively actuated to form a curved guide. The curved path for following by the bo…
