    • A log turning machine is described in which a support frame mounts a rotary cutter with a log receiving opening positioned to receive an elongated log workpiece that is moved relative to the support frame in a forward direction of travel along an axis. The rotary cutter is operable to cut the log workpiece to a prescribed diameter centered on the axis. A set of elongated guide members having opposed first and second ends are mounted to the support frame by sets of links for adjustable movement substantially radially with respect to the axis between a minimum and a maximum cutting diameter. The first ends of the guide members are positioned downstream of and adjacent the rotary cutter and extend substantially parallel to the axis by a distance that is a multiple of the maximum cutting diameter. Guide member positioners operatively connect at least some of the guide members and support frame to enable selective adjustment of the guide members substantially radially between the minimum and maximum diameter. A cutter head and support frame adjuster may also be provided to enable positioning of the cutter head and axis for adjustment of the cutting diameter relative to a log infeed plane.
    • 描述了一种对数车削机器,其中支撑框架安装旋转切割器,其具有定位成接收沿着轴线的向前行进方向相对于支撑框架移动的细长对准工件的对数接收开口。 旋转切割器可操作以将原木工件切割成以轴为中心的规定直径。 具有相对的第一和第二端的一组细长的引导构件通过一组链节安装到支撑框架,用于可调节的移动,其基本上径向地相对于最小切割直径和最大切割直径之间的轴线。 引导构件的第一端位于旋转切割器的下游并与其相邻,并且基本上平行于轴线延伸一个最大切割直径的倍数的距离。 引导构件定位器可操作地连接至少一些引导构件和支撑框架,以使引导构件能够在最小和最大直径之间大致径向地选择性地调节。 还可以设置刀头和支撑框架调节器,以便能够定位刀头和轴线,以相对于原木进给平面调节切割直径。

    • An apparatus and method for machining the surface of logs, in which the log is longitudinally advanced through an opening provided in a rotor disc and the surface of the log is machined by rotatable cutting heads mounted on respective supporting arms pivotably connected to the rotatable disc and rotating therewith around the logs. The cutting heads are rotated around respective axes of rotation, while concurrently the cutting heads rotate with the rotor disc around the log such that the net rotational speed of the cutting heads at the surface of the log is the sum of the speed of rotation produced by the rotatable disc and the speed of rotation of the cutting heads around their respective axes. In the course of machining the logs, the speed of rotation of the rotor disc is varied as a function of conditions at the surface of the log and the rotational speed of the cutting heads around their axes is varied in relation to the rotational speed of the rotor disc to maintain a substantially constant net rotational speed of the cutting heads at the surface of the log.
