A feed roller is provided with feed roller head having a helical carbide gripping inserts. The gripping inserts extend along a helical path and are configured to grip and shift a work piece in a predetermined direction. The gripping inserts are secured to the feed roller body in a helical slot formed between a wall of the feed roller body and a plurality of clamping wedges. The clamping wedge facilitates locking and securing the gripping insert to the feed roller body in a radial direction in response to centrifugal forces created as the feed roller head rotates.

Embodiments provide methods, apparatuses, and systems for cutting wood workpieces, such as logs and cants, into desired products. In various embodiments, after a log is chipped into a cant, the cant may be scanned and re-optimized based on the new scan data and information about the source log, such as simulated orientation parameters, a 3D model, and/or potential cut solutions. In other embodiments, data from multiple sensor types may be used in combination to detect splits in logs, cants, or both. Optionally, re-optimization and split detection techniques may be used in combination to improve wood volume recovery, value, and/or throughput speed.

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.

In various embodiments, a feeding device may comprise a support having feed cylinders arranged in a free end of a respective supporting arm and driven in rotation, wherein the supporting arms in a supported end are journalled in the support on shafts extending in parallel with each other and are pivotable about the shafts between a home position and a pivoted work position, and wherein the supporting arms are mutually connected to each other via a system of articulated links and by means of the links are forced to pivot jointly about their respective shafts, and a movement damping element, which is separate from the support, is integrated in the system of links and independently from the support configured to brake the return movement of the supporting arms from the pivoted position.

A wood board feeding system for positioning in a parallel orientation longitudinal pieces of lumber. It comprises a feeding conveyor assembly configured to receive and convey the longitudinal pieces of lumber over a conveying area in a conveying direction. The feeding conveyor assembly comprises a first conveyor sub-assembly and a second conveyor sub-assembly, both comprising a conveyor for conveying the longitudinal pieces of lumber about one of their ends and a motor driving the conveyor at a conveying speed. The first conveyor and the second conveyor are disposed side-by-side with respect to the conveying direction, thereby the first conveyor sub-assembly and the second conveyor sub-assembly position a respective one of the two opposite ends of the longitudinal pieces of lumber.

A machine including: a table having a surface adapted to have a workpiece lay and move thereon, and a vise for gripping the workpiece. The machine also includes a drive system for moving the vise and workpiece a distance along the table surface, and a sensor assembly connected to the vise for measuring an amount of slip distance occurring between the vise and the workpiece. The machine also includes a control unit connected to the sensor assembly and the drive system for storing the measured slip distance and for operating the drive system and for operating to do at least one of, when a predetermined amount of slip distance is detected: sounding an alarm and stopping further movement of the workpiece, and, when a slip distance is measured, for causing the drive system to move the vise and workpiece an added distance equal to the measured slip distance.

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.
