Primary Breakdown
The Simple “Skew and Slew” Log delivery system
The ability to skew logs for maximum recovery is a must in today's market. Maximizing recovery means, maximizing profits. The Tru-Position infeed system is the only system that can accurately place skewed logs on a sharp chain as presented by the log turner. Tru-Position places the log's center of mass on the center of the chain allowing the longest length timbers and boards to be produced with minimal trim loss. In addition, the log is scanned for processing while it is firmly impaled on the sharp chain and does not have to make any more transitions leading into the canter twin.
The system includes our rugged Slant cant module that allows the heads to move on a slant causing the knife angle of attack remains consistent regardless of diameter, virtually eliminating snatching and surging as the log enters the canter. Canter heads are typically mounted too high which cause surging particularly on smaller logs. Our Stabilizer roll design further assists in eliminating log torqueing especially with uneven chip loads. With surging and snatching eliminated, chipped face quality and sawing deviation are drastically improved.
Consistent accuracy on the opening pass is essential to success downstream. Skewing ability allows larger and longer length timbers to be produced from every log. Our reliable system components, superior dogging qualities and precision of the OSI chain consistently provide our customers with the highest payback in both the softwood and hardwood industries.

The proper relationship of the canter head centerline to the top of the sharp chain is critical to trouble free operation. Horizontally mounted canter heads are often too high, even for the average diameter log and surging, especially on smaller logs is a huge problem.
Our Slant Canter prevents surging by maintaining consistent knife angle of attack regardless of log diameter. With our design the heads are set correctly for every log diameter. Stout anvils are key to flawless canter performance. OSI anvils are built to maintain position and provide trouble free operation. We recommend using solid heads for any canter and can supply any make of heads with our slant canter. If you are already using solid disk heads, they can be re-used on a new canter.
The OSI Sharp Chain drive is the most rugged in the industry and features an oversized Eskridge heavy duty torque hub gear reducer that is flange mounted to the massive drive base. The electric motor is fitted to the machined base and features adjusters for precision coupling alignment. The motor and torque hub are connected via an input shaft adapter and heavy duty elastomeric coupling. Our precision machined head sprocket mounts directly to the torque hub and features bolt-on replaceable teeth. This drive was designed with simplicity and reliablity in mind and provides years of trouble-free service.
Rolls are Mechanical Tubing with extra thick walls. Rolls Supported on 3-15/16" shafts turned to 2-15/16" for 4 bolt roller bearings.
Replaceable Hardened tooth turning sprockets, located on 2'-0" centers. Steel ribs at each sprocket for aggressive turning of flared butt and knotty logs.
Two direct coupled hydraulic motors mounted to end of turning rolls. Support frame constructed of 1/2" wall tubing with pivoting parallelogram action.
Pivots use four bolt roller bearings for articulation. The loader is actuated by a hydraulic cylinder for optimized control of up and down motion.
Turning rolls designed to have skewing ablility for optimized recovery.
For years conventional sharp chain systems have been the mainstay in the sawmill industry. We offer complete systems as well as indiviual machines to get your sharp chain line in top-notch shape.
