A lumber edger is a saw used to straighten and smooth rough lumber or bowed stock by making a cut along the sides of the boards. The result of this process is dimensional lumber.〔(Sawmills eTool: Log Breakdown > Saws > Edgers )〕 In a saw mill the edger is next in line from the head saw. The feed and press rollers on the edger are usually powered, passing the lumber through the machine. The length of feed and tables depends upon the lumber produced by the head saw.〔(The Edger | Saw Mills )〕 Edgers can be categorized as gang or shifting edgers. In gang edgers the saws remain stationary. In a shifting edger the saws can move left or right independently of one another. This allows setting the saws to best maximize the product that can be produced from a particular cant. ==See also== *Gang saw *Sawmill *Head saw *Resaw 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「lumber edger」の詳細全文を読む スポンサード リンク
