Embodiments provide a log positioning system configured to transport a log through one or more chipper/profiler modules to produce a cant with four chipped/profiled sides. In some embodiments, a log processing system may include an infeed, a positioning feed module downstream of the infeed, and one or more chipper/profiler modules disposed proximal to the positioning feed module. The positioning feed module may include a sharp chain coupled to one or more pairs of vertical positioning rolls. The positioning feed module may be selectively skewed, slewed, and/or tilted to match the vertical and angular orientation of the infeed.

A power carpentry feeder machine includes a power source; a rotary wheel operatively coupled to the power source; horizontal guide rods horizontally coupled to the power source; a horizontal movement unit including two movable blocks having horizontal guide holes to receive the horizontal guide rods therein, locking members attached to the movable blocks, a connection block interposed between the two movable blocks and including vertical guide holes, and jointing members jointing the movable blocks to the connection block; a mounting base including a base board and vertical guide rods vertically coupled to the base board and extending through the vertical guide holes; and a vertical movement unit including springs encompassing the vertical guide rods to set the connection block under the springs and a clamp block having clamping holes to receive the vertical guide rods to extend therethrough so as to set the clamp block on the springs.

A feed roller assembly of a harvester head of a forestry machine includes a pivoted arm operated by a hydraulic cylinder and a feed roller and one operating device attached to the pivoted arm having an attachment hub driving the feed roller, the feed roller includes at least one attachment flange, at least two toothed discs, spacer pieces between at least the attachment flange and the toothed discs, attachment bolts connecting the attachment flange, the toothed discs, and the spacer pieces to form the feed roller as a bolted construction, and a cleaning comb attached to the arm for cleaning gaps formed between each pair of components when the feed roller is rotating.

A cutting apparatus for cutting a workpiece, the cutting apparatus including a first housing portion and a second housing portion, a saw supported by the first housing portion, and a feed mechanism supported by the second housing portion. The cutting apparatus includes a height adjustment mechanism for adjusting a distance between the first housing portion and the second housing portion whereby the height adjustment mechanism positions the feed mechanism relative to the first housing portion. The feed mechanism is operable to move the workpiece through the apparatus to be cut by the saw.

A stock guide assembly guides movement of stock along a work table. The assembly includes a base and a roller operatively connected to the base to engage stock and hold it against the work table. In some embodiments, a biasing member yieldably biases the roller to urge the stock toward the work table and accommodate changes in thickness of the stock. The roller can be mounted at a skew angle to urge the stock toward a fence of the work table. The assembly can include a shaft movable with respect to the base for translationally adjusting the distance of the roller from the base and rotatably adjusting the distance between the roller and the work table. The roller can be rotatably mounted to the end of an arm oriented relative the work table so stock kickback drives the arm to pivot and drive the roller toward the work surface.

In a method for separating a sawn timber pack obtained from one trunk into main yield and side cuttings using a separating conveyor, the sawn timber pack is conveyed in a longitudinal direction via an underside transport device of the separating conveyor. While the single- or multi-piece main yield is supported by the transport device, one or more side boards are separated transverse to the conveying direction using gravitational force and/or external forces, whereby lateral retaining elements are briefly opened for release. In order to be able to process trunks with as large a diameter range as possible, the side boards located on opposing sides of the sawn wood pack are separated in two successive separating stages, whereby the lateral retaining elements of the separating conveyor are opened on one side on a respective release side in the successive separating stages.

A feed roll comprises a roll having a rotary axis, flutes fixed on the roll, mounts fixed on the roll between the flutes, each mount having a seat spaced apart from the outer surface of the roll and replaceable flute elements detachably and matingly engaged in the seats of respective mounts and extending outward beyond the mounts. The replaceable flute insert element comprises an elongated plate body having an inner longitudinal edge, an outer longitudinal edge, and a backing face extending between the inner longitudinal edge and the outer longitudinal edge and the inner longitudinal edge and the backing face configured to matingly engage the seat of the mount. The flue insert element further comprises the outer longitudinal edge being formed with a traction element and the plate body having a plurality of bolt holes therethrough for registering with the bolt holes of the mount element when the plate body and the seat are matingly engaged.

The adjusting device for a pressure roller of a processing machine has a pivotable support arm carrying a pressure roller adjustable with the support arm from a pressure position into a resting position. The support arm is seated on a support rod that engages a clamping aperture of a pressure roller bracket. The support rod has a first section with noncircular cross section that forms a form-fit section cooperating with the clamping aperture of the pressure roller bracket by form-fit. The support rod has a second section arranged axially offset to the first section and forming a rotary section. It rests against the inner side of the clamping aperture and allows rotation of the support rod about its axis in the clamping aperture. The pressure roller can be pivoted easily into a resting position and/or transverse to the workpiece in the width direction with a constructively simple design.
