Wood-Mizer’s Edger Multirip range
The range offers a full line-up of entry-level, light and heavy industrial single or double arbour edger and multirip solutions that can work as standalone units or slot into existing lines.
The focus of the range is to make affordable, scalable, and modular edging and multirip solutions available to sawmillers that can fit into the budgets and production targets of sawmills irrespective of their size.
This gives start-up and industrial producers equal access to one range that includes entry-level and high-production capacity machines with the ability to either add standalone units to existing lines or design and build new lines with edging and multirip solutions from Wood-Mizer part of it.
The scalability of the range adds further choice with entry-level edgers and multirips offering basic capabilities with more power, output capabilities and options giving, adding additional punch for producers needing higher capacity edgers or multirips.
Investing in a product range supported globally by a professional after-sales service network for a sawmill’s lifespan makes partnering with Wood-Mizer an even bigger win for sawmillers.
Edgers and Multirips – Adding value to a sawmill?
There is a lot of overlap between the design, function and benefits that edgers and multirips offer.
Both machining platforms have robustly designed frames that give the torsional rigidity needed to support the arbours and circular blades that cut accurately sized timber consistently at high speed and volumes over time.
Both are used during the secondary breakdown phase of the sawmilling process to break or cut the components that exit the primary breakdown stage down further.
Edgers edge, trim or square sideboards or slabs and flitches with wane from the primary breakdown phase into a uniform-size product. Multirips rip cants and blocks exiting the primary breakdown phase into boards.
Both also offer specific benefits that allow sawmills to improve efficiencies, increase productivity, boost recovery and bolster the safety levels of a mill.

Images above & below: The cutting patterns that produced by edgers and multirips.
Less resharpening
An edger and multirip can work across shifts without blade changes. Although circular sawblades cost more than bandsaw blades, they require less resharpening and fewer delays to change blades, with this reducing the workload to resharpen blades with more uptime in a shift producing more boards.
Reduce maintenance costs
Using edgers and multirips simplifies the operation with fewer machines that must be maintained, slashing running costs and higher volumes adding to the bottom line.
Improved material and waste handling
The simpler material flow that an edger and multirip offer streamlines material handling and waste removal processes to boost efficiency and slash costs.
Manufacturing quality
The guideline that shapes Wood-Mizer’s edger multirip range is to produce machines that deliver the cutting accuracy and size tolerances needed by timber producers that invest in the range.
Properly aligning the feed rollers and arbours is critical in achieving the required cut tolerances.
If the required alignment standards are not met, it can cause a range of problems other than not cutting straight.
Bearings will fail faster, and blades will become blunt sooner because they do not run true in the cut. With more strain on all the parts, breakdowns and upkeep will increase.
To overcome this, some companies use costly equipment to get the alignment needed resulting in an excellent end-product but at a very high price.
Others cut costs by fabricating machine frames from tube steel and using cheap bearings. Such frames don’t have the torsional strength to withstand the forces experienced by these machines, so the system’s alignment degrades over time.
Some systems integrate re-alignment tools into the bearing seats. While this may allow very skilled artisans to align a machine properly, it can be done wrong by an inexperienced technician.
The result of improper alignment is that the machine will struggle to feed, blades will dish, power consumption will go up and bearing life suffers.
Wood-Mizer uses a strong and rigid frame for its edger and multirip range made from thick plate. The components are pre-cut on CNC systems and then webbed and welded together for a rigid structure with exceptional alignment.
Bearings for both rollers and arbours are bolted into position with no need for further alignment procedures, and this eliminates any guesswork when replacing components in the field.
The result is consistent accuracy without fail.
