摘要： A bi-directional cutting band mill apparatus utilizes two band saws mounted on a carriage for cutting horizontal sections from logs through successive back and forth passes across each log as the carriage reciprocates on a lower frame wherein a section of the log is cut with one band saw in one pass and then a next section of the lumber is cut by the other band saw as the carriage travels in the opposite direction in the following pass. The bi-directional cutting band mill apparatus includes structural elements that allow for the coincident raising and lowering of both band saws and structural elements that provide for the sequential and incremental adjustment of each band saw preparatory for cutting the sections from the log so that each respective band saw can be positioned for making the appropriate depth of cut through the section of the log during that respective pass of the respective band saw.
