SPIKE ROLLER FOR AXIAL FEEDING OR ROTATION OF A LOG |
摘要 |
A roller for grasping a log for axial movement or rotation of a log, the roller including spike bar retainers fastened on the cylindrical surface of the roller. The spike bar retainers accept and retain replaceable spike bars, thus facilitating replacement of worn spikes, which may be replaced without removal of the roller. The spike bars formed of alloy steel feature an improved type of spike having planar side surfaces that converge to a pointed end. The improved spikes grip and hold logs at lower average pressures over an extended period of use than conventional conical spikes.
