    Description

    The drawing on the opposite page depicts the commercial version of the Koch shaping-lathe headrig. This first production model, design of which is based on data derived from prototype trials described in the present paper, will be commercially making southern hardwood flakes and pallet cants by early spring of 1975. It carries a 54-inch-long, six-knife cutterhead with 12-inch cutting circle. The cutterhead is turned at 3,660 r/min by a 300-hp motor designed to momentarily carry a 200-percent overload without pullout from synchronous speed. The workpiece is driven from one end with a 5-hp, variable-speed motor that provides rotational speeds from 9 to 27 r/min. The headrig will accept bolts 3.5 to 12 inches in diameter and 40 to 53 inches in length. Feed rate is estimated at six bolts per minute. This initial production model was built under a Southern Forest Experiment Station contract with Stetson-Ross, Seattle, Wn.; funds were provided by the Branch of State and Private Forestry, USDA Forest Service.
