Method and device for active wedge error compensation between two objects that can be positioned substantially to parallel to each other
摘要：
The invention relates to a method and device for expanding the travel or control displacement of linear actuators that is available during an imprinting or embossing stroke. The wedge error compensating head (2) comprises a movable part (4), a stationary part (3) and at least three linear actuators (8). Each linear actuator (8) is connected to one of the parts (3, 4) at one end and to the other of the two parts (4, 3) by wedges (9) at the other end. By means of the wedges (9), it is possible to coarsely or roughly compensate for wedge errors and possible tolerances of individual subcomponents of the system. The linear actuators (8) are only used for fine or precision compensation for the wedge error. In this way, sufficient control displacement is available for the imprinting stroke with the linear actuators.
摘要（中）：

本发明涉及一种用于扩展在压印或压花冲程期间可用的线性致动器的行进或控制位移的方法和装置。 楔形误差补偿头（2）包括可移动部分（4），固定部分（3）和至少三个线性致动器（8）。 每个线性致动器（8）在另一端通过楔（9）在一端连接到部分（3,4）中的一个并且两个部分（4,3）中的另一个连接到另一端。 通过楔形（9），可以粗略地或粗略地补偿系统的各个子部件的楔形误差和可能的公差。 线性执行器（8）仅用于精确或精确补偿楔形误差。 以这种方式，足够的控制位移可用于具有线性致动器的压印行程。
