An Operator's Dream
3-D Small Log Scanner
Each scan head measures just 2-1/2'' x 5'' x 15'' for a comparatively small profile. The unit utilizes Cutler-Hammer/Opcons independent scan head feature, introduced on the Opcon 400. This gives the systems integrator the flexibility to customize scanner frame designs to individual installations.
Complete 3-D profiles around the log are taken every 0.6'' along its length while traveling at 300' per minute. Modular design permits one to eight heads to be configured together. The only interface needed to the scan heads is a high-speed fibre optic link back to a plug-in card in the host computer.
A typical four-head scanning system will produce more than 1,000 data points from around the circumference of the log on every scan. The 450 eliminates the necessity for field calibration; one-time factory calibration is all that is required; this and the elimination of light shield shrouding means mill startups are quick and easy, says the manufacturer.
Portable Band Sawmill
Log rotation is programmable, as are the setworks. Other features include a kerf of less than 1/16', digital readout and easy-touch controls, adjustable guides, upper and lower travel limits, synchronous drive belt carriage feed and a high-travel cable track chase.
Board Thickness Profiler
Moved along the board (maximum 6'' width and 1'' thickness), the device measures up to 512 equally spaced intervals per board. The device has an onboard computer with LCD display. Data collected is downloaded into a PC (minimum 8 megabytes of RAM) for analysis of problems such as snake, snipe, washboarding, bevel and taper. The BoardRunner can download directly into a SI-CAM program.
Alberta Forestry Supply Sector Booming
We think the numbers are pretty impres-s ive for such a young sector, reports FISAA president Reg Belyea. We werent able to talk to all of the companies involved, but even so, this level of sales and employment susggests the supply sector is becoming a very important part of the economy. Many of FISAAs 280 members have serviced the energy sector for years, diversifying into forestry.
Morbark Model 4000
With the upgrade, the machine now features a motor driven feed with automatic stop. With a magnet placed on the back of a blade, the grinder will shut off automatically when the magnet comes full circle. The Dino Setter is a semi-automatic setting machine for blades up to 2'' in width. A hand crank turns a shaft with cams which feed and clamp the blade as well as set both left and right teeth in one pass. Because the blade is clamped each time a tooth is set, accuracy is quite high, says the company. Blades can be set at a rate of 100 teeth per minute.
Windows LSIZE Program
The system offers seamless integration of data collection and analysis needs from the mill floor to long-term trend analysis. Some new features of Windows LSIZE include the ability to save years worth of size measurements in the database, display multiple charts of the screen simultaneous-ly, and export measurements for use in other products such as Microsoft Excel. The time series charts (X Bar & R, Standard Deviation, Taper & Wedging ) can show up to 25,000 points, and each point can rep resent a single subgroup (board, panel, etc.), a daily average, weekly average, or monthly average.
Histograms can display set and calculated limits along with the normal curve from collecting and analyzing measurements on the mill floor with the MicroPak to down-loading these measurements for long-term analysis.

New Selcom Laser Sensors
Based on the principal of laser triangu-lation, the SLS 5000 and 6000 project a spot illumination 16,000 times a second on the object being measured. It is insensitive to light, surface texture and plant environ-ments. The result is fast, automatic and continuous adjustment of the sensor during rapid changes in colour or wood surface, including the presence of bark, knots, cracks or depressions.
Vertical Fingerjoint System
The system is priced at less than US $100,000, says the manufacturer.
