This invention relates to a process for the division of an individual input source log into discrete longitudinal lengths for subsequent processing. The process comprises receiving an individual input source log, dividing the input source log into one or a plurality of output log portions of a predetermined length, wherein at least a portion of said output log portions resultant from said division are of a substantially equal or substantially constant or consistent longitudinal length, and wherein said substantially equal or substantially constant or consistent longitudinal length output log portions are procured as a feed stream of log material for a subsequent processing step. This process provides for the processing of logs and subsequent assembly into an end product formed from a composite of sticks derived from said processed logs.

A hydraulic separation system and method enables efficient recycling of log yard waste from an elevated frame. The system separates fine granules, small rocks, small bark, large bark, and large rocks with a variety of sequentially positioned, hydraulically powered separating components. The separation is mechanical and the size and weight of the individual material determines where in the system it is separated. Conveyors carry the log yard waste through the system. Shaking screens shake in a fast, up and down motion to flip and move the material through the system. Adjustable sloped plates work to accelerate and decelerate the material through the system. Dampening fingers control the disposition of elongated pieces of large bark and help to decelerate down the material. Blowers separate the bark from heavier rock and granular material. The elevated frame to enable cleaning and access to materials discharged beneath the elevated frame.

A log scanning system and method for scanning a log load. Each individual log in the log load may have an ID element with a unique log ID data on at least one log end face. The system has a handheld scanner unit for free-form scanning by an operator over a load end face of the log load. The scanner unit has a depth sensor configured to capture a series of depth images of the load end face and a texture sensor configured to capture a series of texture images of the load end face during the load end face scan. The system also has a data processor(s) that receives and processes the depth and texture images captured from the scan. The processor(s) are configured to fuse the depth images or depth and texture images into a data model of the load end face, determine log end boundaries of the individual logs visible in the load end face by processing the data model, process the texture images to identify and decode any ID elements visible in the scan to extract individual log ID data, and generate output data representing the log load based on the determined log end boundaries and extracted log ID data.

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.

The invention relates to a system and a method configured to orient a plurality of studs into one and the same curvature based orientation. The system comprises a conveyor (108; 105) having a feeding direction and being arranged to receive a stud (200A, 200B) being oriented with its longitudinal extension in a direction transverse to the feeding direction. The system further comprises a sensor arrangement (160) configured to measure the curvature of the stud (200A, 200B) as seen along its longitudinal extension and as seen in a major plane of the conveyor (108; 105). Additionally, the system comprises a turning arrangement (170) configured to turn the stud (200A, 200B) 180 degrees around its longitudinal extension.
