    Abstract: The self-centering feeding device (20') for elongated objects such as logs includes a conveyor means (30) carried by a parallel mechanism having a vertical stationary part. The parallel mechanism is connected to a mechanical engagement means (26) and is controlled by a driving means (28) activated when an object on the conveyor means reaches a predetermined position, and is then kept activated the whole time during which the object is fed-through. The object is thus firmly clamped between the conveyor means and the engagement means and has no possibility to rotate about its longitudinal axis. The conveyor means may therefore be much shorter than the object. The invention is suitable for general application, but in particular for application in the log processing industry.

    Abstract: Disclosed herein is a rotary delimber for a timber harvester in which the branches are severed from a tree trunk as the tree trunk is fed axially through a hollow rotor carrying a plurality of cutters. Each cutter is secured to a spindle rotatably supported in a cutter arm for movement about an axis transverse to the axis of the rotor. A torsion bar in each cutter arm is connected to the spindle to yieldably bias the cutter inwardly toward the axis of the rotor. The cutter arms are rotatably supported on circumferentially arranged spindles secured to an outturned flange on the rotor for movement toward and away from the axis of the rotor. Torsion springs yieldably bias the cutter arms inwardly toward the axis of the rotor. Each cutter arm is provided with a cam plate which is engageable with a roller on a clutch arm mounted on an axially movable clutch ring. The clutch ring is splined to the rotor and movable axially of the rotor by one or more hydraulic cylinders to cause engagement of the rollers with the cam plates to move the cutters and cutter arms away from the axis of the rotor to receive tree trunks of varying diameters.The rotor is yieldably mounted on a vehicle frame to afford displacement of the rotor about horizontal and vertical axes.

    Abstract translation: 本文公开了一种用于木材收割机的旋转定界器，其中当树干通过承载多个切割器的中空转子轴向进给时，树枝从树干上切断。 每个切割器被固定到可旋转地支撑在切割臂中的主轴，以围绕横向于转子的轴线的轴线移动。 每个切割臂中的扭杆连接到主轴，以可靠地将切割器向内朝向转子的轴线偏置。 刀臂被可旋转地支撑在固定到转子上的转向凸缘的周向布置的主轴上，以朝向和远离转子的轴线移动。 扭转弹簧能够使切割臂向内朝向转子的轴线偏置。 每个切割臂设置有凸轮板，该凸轮板可与安装在可轴向移动的离合器环上的离合器臂上的辊接合。 离合器环花键连接到转子并通过一个或多个液压缸在转子的轴向上移动，以使辊与凸轮板接合以使切割器和切割器臂远离转子的轴线接收不同的树干 直径。 转子可靠地安装在车架上，以使转子绕水平轴和垂直轴线移动。

    Abstract: A DEBARKING MACHINE OF THE HOLLOW HEAD TYPE WHICH TRANSFERS LOSS ALONG A PRESCRIBED PATH WHILE PROGRESSIVELY REMOVING THE BARK THEREFROM BY A PLURALITY OF DEBARKING TOLLS WHICH ARE ROTATED CIRCUMFERENTIALLY ABOUT THE LOG BY A ROTATABLE TOOL HOLDER. THE LOGS ARE DRIVEN BY A PLURALITY OF FEED ROLLS, EACH FEED ROLL INCLUDING AN ELECTRICAL DRIVING MOTOR HOUSED THEREIN, AND THE DEBARKING TOLLS ARE FORCED AGAINST THE LOG PASSING THEREBY BY FLUID CYLINDERS SUPPLIED WITH FLUID UNDER PRESSURE FROM A PLURALITY OF FLUID PRESSURE PUMPS CARRIED BY THE TOOL HOLDER AND ACTIVATED BY A PUMPING CAM AS THE TOOL HOLDER IS ROTATED.
