  • Patent number: 12011844
    Abstract: A bundle breaker has upstream and downstream breaking supports and first and second platens located above the breaking supports that are configured to be raised and lowered by actuators to selectively clamp a log between the platens and the breaking supports. A third actuator applies a shifting force to the downstream breaking support to shift an input end of the downstream breaking support relative to an output end of the upstream breaking support to break a second portion of the log from a first portion of the log. A controller controls the first actuator and the second actuator and the third actuator. Also, the controller is configured to stop or reduce the application of the shifting force in response to a determination that the second portion of the log has broken off the first portion of the log.
