A portable sawmill which has an elongate central portion, at least one hinged foldable extension portion, laminated rails, detachable axle/wheel combinations, a tow bar, and adjustable legs. Spacers are received between each rail and the respective support structure for both the central portion and the extension portion, including one spacer a first portion of which is disposed between and attached to each rail and support structure of one of the central portion and the extension portion and a second portion of which is slidingly receivable between each rail and support structure of the other of the central portion and the extension portion as the extension is unfolded for use. A pull cable, when an actuation lever is engaged, effects pivotal movement of a cam to which another pull cable is attached for actuating the engine throttle for cutting wood. At least one other pull cable or other actuation member is attached to the cam to actuate at least one other device upon the actuation of the throttle.

A sawmill assembly includes a bed and a carriage. The bed has a pair of substantially parallel rails, and the carriage is movably supported along the rails. The bed includes an extension bed member pivotably attached to a main bed member with a combination bunk/hinge to allow an operator to fold the bed between an extended in use position and a stowed position for transporting the sawmill assembly to or from a work site with a tow vehicle.

A portable sawmill has an elongate central portion, at least one hinged foldable extension portion, laminated rails, and a tow bar. An elongate tubular axle retaining member is mounted to the base. A pair of torsion axles, to which wheels and tires are attached, are received telescopically in opposite ends respectively of the axle retaining member and detachably attached thereto. A plurality of legs are attached to the base. The legs are height-adjustable to raise the base to a height such that the tires are raised above the ground so that the axles with the attached wheels may be removed.

An apparatus for separating a sawn timber package cut from a log into main and side products during longitudinal transport thereof, having at least one separating device positioned such that, during a feed motion of the sawn timber package, it engages in a sawing gap between single- or multi-cut main product and side product and deflects the side product in a direction leading away from the main product. Two rotatably mounted conical rollers form the separating device, each having a circumferential separating edge formed by two surfaces of revolution enclosing an acute angle, and the two conical rollers are arranged on both sides of the sawn timber package and oriented such that they engage laterally into the sawing gap with respective separating edges and roll on the main product with their first surface of revolution, while deflecting the side product from the main product with their second surface of revolution.

A band saw machine is adapted for cutting a lumber, and includes a frame body unit, a transport unit, a cutting unit, a cleaning unit and a guide unit. The frame body unit includes a base plate and a hood body extending rearward from the base plate and cooperating with a conveyor belt of the transport unit to define an output passage. The cutting unit is adapted to cut the lumber into an upper piece and a lower piece. The guide unit includes two guide rollers mounted to the hood body, extending into the outlet passage, and adapted to separate the upper piece from the lower piece. The cleaning unit includes an air lance for directing an air stream to the conveyor belt.

A band saw machine is adapted for cutting a lumber, and includes frame body unit, a transport unit, a hold-down unit, a cutting unit and a drive unit. The transport unit includes an endless conveyor belt extending in a front-rear direction through the frame body unit for transporting the lumber. The hold-down unit includes an endless hold-down belt extending in the front-rear direction through the frame body unit. The endless conveyor belt and the endless hold-down belt are driven by the drive unit to rotate synchronously to carry the lumber to be cut by the cutting unit.
