Abstract
A saw carriage or module for manually, semiautomatically or automatically cutting stems typically supplied by a stem handling apparatus, which stem handling apparatus delivers full-sized, substantially tree-length stems to one or more of the saw carriages for cutting into logs, poles or other segments. During automatic operation of the module(s) stems are typically scanned by an optical device and the physical characteristics of the scanned stem are sent to a computer, which selects the cutting pattern and transfers this information to a programmable logic controller. The programmable logic controller typically orchestrates positioning of one or more linearly-adjustable saw carriages or modules and on-board carriage saw blades to optimize cutting of the stems into the segments. After the modules and saws are so positioned, each stem is sequentially transferred by the handling apparatus to the saw modules, where it is positioned, clamped and cut into multiple segments at the preselected optimum points. Stem segments are ejected from the saw carriages or modules by ejecting devices provided on each module.
