    摘要： At a sawmill a device at the input side of the sawmill for adjusting automatically a log or a similar elongated object to be sawn relative to the center line or sawing line through the sawing unit so that a straight line through the centers of the end surfaces of the log becomes parallel to and coincident with the sawing line, if the log is straight, but parallel to and transversely offset from the sawing line, if the log is curved or bent, said transverse offset having a direction opposite to the direction of the curve or bow in the log and a magnitude which is a predetermined proportion of the height of the curve or bow in the log.

    摘要： A method and apparatus for protecting a die from damage due to material jams in material stamping equipment wherein feed material is stamped in a die and then advanced through the die by action of press feed rolls powered by a press feed roll drive motor. The position error of the press feed rolls or the torque of the press feed roll drive motor is monitored during the advance of the feed material through the die. The monitored position error of the press feed rolls or the monitored torque of the press feed roll drive motor is then compared to the expected position error of the press feed rolls or the expected torque of the press feed roll motor, respectively. The feed material is moved backwards to a previous position from which the feed material advanced, typically the position at which the feed material was last stamped, if the monitored position error of the press feed rolls or the monitored torque of the press feed roll drive motor deviates by more than a tolerance value from the expected position error of the press feed rolls or the expected torque of the press feed roll motor, respectively. Operation of the material stamping equipment may stopped after the feed material is moved back if desired.

    摘要翻译： 一种用于保护模具免受材料冲压设备中的材料堵塞造成的损坏的方法和装置，其中将进料材料冲压在模具中，然后通过由压力进给辊驱动马达驱动的压力进给辊的作用而推进通过模头。 在进给材料通过模具的进给期间，监测压力进给辊的位置误差或压力进给辊驱动马达的扭矩。 然后将压力进给辊的监视位置误差或压力进给辊驱动电机的监控转矩分别与压力进给辊的预期位置误差或压力进给辊电机的预期扭矩进行比较。 如果压力进给辊的监视位置误差或压力进给辊驱动电机的监视转矩，进给材料向后移动到进给材料从其进给的先前位置，通常是进料最后冲压的位置 分别从压力进给辊的预期位置误差或压力进给辊马达的预期扭矩偏差大于公差值。 如果需要，送料回送后，材料冲压设备的操作可能会停止。
