A lumber cutting and delivery system for use in assembling trusses on a truss table includes a saw configured to receive a piece of material therein. The saw is configured to cut the piece of material into one or more pieces and at different lengths and angles so that at least some of the one or more pieces are the components of at least one truss. A trunk conveyor system is positioned to receive the one or more pieces cut from the saw. The trunk conveyor system has a first conveying element to transport the one or more pieces over a distance in a travel direction and an ejector configured to discharge the one or more pieces from the first conveying element in a first discharge direction. A branch conveyor system is configured to receive the one or more pieces discharged from the trunk conveyor system in the first discharge direction. The branch conveyor system has a main conveying element to transport the one or more pieces.

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.

In some embodiments, a cutting system including a movable blade or a reciprocating blade operably coupled to a motor is disclosed, wherein the cutting system comprises a diverting feature. In some embodiments, a diverter proximity relative to the movable blade or reciprocating blade is selected to facilitate diversion of a material during cutting. In at least one embodiment, the movable blade may be movable blade for an oscillating tool. A cutting system according to the present invention may be coupled to a container, for example, a residential trash container or a residential recycling container.

A carpenter's accordion is disclosed herein. The carpenter's accordion is a portable, compactable, and free-standing tool that may be advantageously used in combination with a table saw to increase the length of stock that one user can cut with a blade. Generally, the more sections that comprise the carpenter's accordion, the greater the lengths of stock one user will be able to cut using a table saw or other similar tool in combination with the accordion.

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 method of wood shingle classification and sawing using machine vision comprises the steps of taking an image of a wood slab in a wood block and identifying a defect in that slab; comparing an image of this defect to images of confirmed defects in a database of confirmed defects to find a match of the defect in these images. If a match is not found, sawing a shingle from the slab and classifying the shingle while making abstraction of the defect. In a second aspect, when images of two consecutive shingles are identical, a third and subsequent shingles can be sawn from a block without taking images thereof. In another aspect, the comparing of images is done by an artificial intelligence system that is trained on a database of images that are associable to the subjectivity of experienced shingle sawyers.

A lumber board cutting apparatus including a housing, an infeed drive, an outfeed drive, a lumber board cutter, and a lumber board gripper including a gripper arm, a lumber board mover connected to the gripper arm, and a lumber board clamper connected to the gripper arm.

The present disclosure provides systems, methods and assemblies comprising one or more tapered feed rolls. Tapered feed rolls may be used to change the rate and direction of workpiece travel along a processing line while retaining the workpieces in sequential order. Routing workpiece flow with tapered feed rolls may allow the workpieces to be tracked along one or more processing lines, and may reduce the operational space required for workpiece processing.
