Abstract
An apparatus for forming workpieces with rounded ends especially for use as webs in timber roof trusses. The apparatus includes a feeding system for feeding workpieces into a row of workpieces arranged along a path of travel and cyclically advancing the row along the path to a rotary cutter tool. A movable conveyor receives workpieces thereon and delivers each workpiece sequentially to a loading position adjacent the upstream end of the path of travel. A pushing device is at the upstream end of the path. A common drive shaft simultaneously powers the conveyor and the pushing device. A stop bar prevents movement of the workpieces in a direction generally transverse the path of travel while the cutter tool is shaping the ends.
