Log positioning device and method

摘要

A method of positioning a log of sheet material includes sensing the presence of a log in a staging area having a length, a midpoint at the center of the length, and a boundary point between the midpoint and an end of the length; sensing the presence or absence of a portion of the log at the boundary point; and moving the log along the length of the staging area. When the log is present in both the staging area and at the boundary point, the log is moved toward the midpoint. When the log is present in the staging area and absent from the boundary point, the log is moved toward the boundary point.
