Systems and methods for improved bandsaw process control and throughput, in which a sawblade of a bandsaw contacts a bottom sawguide mounted in a bottom guide holder, the bottom guide holder frame having a flexural member that transmits forces on the sawguide to a force transducer associated with the flexural member. Workpiece-related forces include deflection forces, both lateral and torsional, and saw resistance forces on the bottom sawguide. An object of the invention is to establish a true cut condition when pre-straining the sawblade and a process control loop whereby the true cut condition is restored in near real time while cutting a workpiece. The combination of a force sensing guide holder and a process control loop synergically improves target lumber size control and maximizes log value, while also increasing throughput by reducing both overfeed and underfeed.

A sawmill feedspeed control system having a force sensor operatively coupled to a sawguide of a sawblade, the output of the force sensor being processed and supplied to a motion controller and driver for reducing or increasing feed velocity of a workpiece so as to prevent overfeed or underfeed, while minimizing deviations of the blade from a straight cut and maximizing production throughput.

Provided are a porous media bearing for a band saw, a band saw for cutting cant and a method of cutting cant using the band saw. The band saw has a continuous loop blade supported by a drive wheel and first and second support arms having porous media bearings. A location of a blade cutting section, an angle of the blade in relation to the cant being cut, and tension on the blade can be adjusted by moving the first and second support arms.

A sawmill for tree logs includes a rocking carriage to pick up fresh logs and feed them into the path of a saw blade, as well further provisions relating to improvements to infeed systems for the fresh logs, as well as to, outflow systems for transfer of sawn-off product to a production line conveyor or the like for further processing to downline processes after the first saw cuts on the fresh logs.

A sawing facility includes a rail guide, a saw arranged on the rail guide, a first carriage arranged on one side of the saw along the rail guide, and a second carriage arranged on the other side of the saw along the rail guide. The first carriage includes a first saw log support and a first carriage drive that can move the first carriage together with a first saw log on the rail guide and past the saw to saw the first saw log. The second carriage includes a second saw log support and a second carriage drive that can move the second carriage together with the second saw log on the rail guide and past the saw to saw the second saw log. The second saw log is loaded onto the second saw log support while the first saw log is sawed using the first carriage.

A timber processing and firewood splitting machine is provided, comprising a self-standing bearing frame for being placed on the ground, a conveying unit arranged in one terminal area of said bearing frame and configured to convey timber of a pre-determined diameter in the longitudinal direction of said bearing frame, a cutting unit suitable for cutting said timber to separate longitudinal sections of a pre-determined length, a guiding unit for guiding each timber section in said longitudinal direction and along a geometric axis (10) towards a working area (5), and a splitting unit and supporting assembly for supporting firewood pieces upon being split apart from the rest of said longitudinal section of the timber.
