Chapman Wins Award
Bob Chapman of Optimil Machinery Inc received the Wood Technology Award
for
Excellence
at the Portland show. Chapman has been involved in the design and
manufacture of sawmill machinery since the 1950s. He designed the edge
chipper and produced the first Chip-N-Saw in the 1960s and later oversaw
the development of new products such as spinning discs, a blender system
for OSB, a chipper knife design and thin kerf technology. In 1983, he
started Chapman Sawmill Machinery, which later became Optimil—a company
producing computer controls, laser scanners and other technologies for
modern optimized sawmills. Chapman has been dedicated to the pursuit of
excellence in the wood products industry throughout his life and is
steering the company towards new endeavours both at home and
internationally. Formerly the Forest Industries Award for Excellence, the
historic award presented to forest industry innovators was reborn this
year after a two-year hiatus. Reader Service Card #678

Algis Automatic Transverse
Grading
The fully automatic transverse grading and inspection system from Algis
Autograding Inc is a modular vision inspection system that looks at all
four sides of each piece of lumber, locates and identifies defects, grades
the board and determines the optimum grade-trim decision. The system uses
machine vision scanners coupled with vision computer technology to grade
each board to individual association grading rules. Designed in two-foot
modules, it can be retrofitted onto any transverse grading table in the
sawmill or planermill. Each module contains its own machine vision
scanner, lighting and grade processor.

Linden/MPM Log Merchandizer
The log merchandizer system from Linden/MPM is designed for high-speed log
merchandizing with either lineal or transverse scanning methods. In the
lineal system the scanned logs are discharged into a Linden log ladder.
The log is then positioned for optimum recovery by either an even-ending
system of hourglass rolls or by a log pusher in the log ladder. In the
transverse system, the scan deck is used in combination with a log ladder
to feed logs to the travelling merchandiser saws.

SLICE Technology from Key Knife
SLICE (spiral lead in cutting edge) Technology from Key Knife Inc is a new
twist for drum style chipping. It reduces the depth and overall area of
fibre pull caused by changes in grain or knots and improves chip quality.
Gains in surface finish quality are made through a slicing action that
makes a smooth cut rather than a chop, with the end result being increased
lumber value. Designed for high feed speed applications such as curve
sawing, SLICE Technology utilizes a knife set-up that is twisted and
tilted to enter the cant at an angle. By utilizing an opposing knife
configuration, a balanced cutting force is created, eliminating excessive
stress and thrust load on the shaft and bearings. Reader Service Card #691
USNR’s Vertical Shape Saw
The vertical shape saw (VSS) system from USNR is an innovation that
features higher yields as it cuts along an optimized path to get the
greatest number of high quality boards from every log. The VSS follows the
wood grain more accurately, resulting in higher quality lumber than a
straight sawing system. Longer boards also result, as the saws follow the
natural curvature of the log. It offers total transition control, greater
throughput, efficient operation, compact design and easy maintenance. The
USNR drying systems division displayed a new powered kiln vent, while the
Perceptron division exhibited a real time lumber size control system that
minimizes saw variation. www.usnr.com

Precision Dowel Mills
Dowel mills from Montana Manufacturing Inc produce precision dowels, deck
railing, fencing material and log furniture components. Each system is
customized to meet client needs. The dowel mills process uniform round
wood with a consistent diameter from 2” to 8”. The operator sets the
diameter of the finished product and any irregularities in the wood are
eliminated. The mills can be stationary or mounted on a truck chassis or
trailer. Optional accessories include infeed and outfeed conveyors and
bundling equipment. www.postyard.com
Reader Service Card #693
Ulti-Vision Board Scanning
Ultimizers Inc offers the Ulti-Vision defect scanner for detecting defects
such as wane and knots using multiple scan camera technology. Top and
bottom scanners find most knots on relatively thin wood, while edge
cameras detect edge knots on thicker wood. Ulti-Vision wide board
multi-sensing scanners offer defect optimization using scatter, colour and
3-D profiling via infrared lasers, top and bottom camera multi-sensing and
top and bottom colour cameras. A typical ripsaw system includes an infeed,
an Ulti-Vision scanner, a transfer, a ripsaw and an outfeed. Operators are
able to see which sizes are being cut and ensure yields are as high as
possible. Ultimizer’s Duo-Drive cut-off saw, with patented top and bottom
conveyor belt drives, is one of the fastest automatic cut-off saws
available, says the company.
