Abstract

An end dogging device for use in a sawmill having a saw cluster allows a plurality of flitches to be cut from a workpiece, such as a log or a cant, in a single pass through the saw cluster. The workpiece is clamped between a fixed end dog and a movable end dog both upstream and downstream of the saw cluster. Each end dog has two or more fingers which are held in spaced-apart relation on a pin joint. During the sawing operation, the saw passes between adjacent fingers. Accordingly, eachindividual flitch is supported by opposing pairs of fingers, one on each end dog, thereby preventing the flitches from twisting or otherwise falling relative to each other flitch and relative to the unsawn portion of the workpiece.
