The next generation in high speed planing
ACORA IS currently installing a Gilbert 850 mpm planer and Acora Handling equipment at TimberLink’s Tarpeena mill which will join the successful installation last year of a Gilbert Planer and Acora handling equipment at Carter Holt Harvey’s Caboolture plant, which has been running exceptionally well for almost year now giving the plant record uptimes and product quality.

There has been a recent revolution in the world of high speed planing due to innovative development and precision engineering by Gilbert Products of North America – these planers are rapidly setting new standards in planer performance and due to this unique design and concept, are very applicable to planning radiata pine at high speed.
The Gilbert Planer is truly revolutionary in it’s design – it was developed by Gilbert after many years of working on repairs to existing planers in the field when they decided they could do a better job – Gilbert spent five years on developing their machine (1995 to 2000) and released the first planer high speed planer in 2000 – since then they have sold more the 50 planers worldwide.
The innovation comes from a ground up design, fabricated to precise standards in Gilberts ultra modern facility – a whole planer frame is entered into the CNC tunnel and machined to precise tolerances.
Perhaps the greatest innovation is the Pull Through Technology
• The planer runs with a gap so does not need a bridge.
• Because of this, there is no end to end impact between boards, and this is the biggest causes of break-ups within a planer, particularly with Radiata Pine.
• CNC closed loop control of all of the heads, means positioning is precise and fast – to set the size, measure the actual size of the piece coming out of the planer, input this on the screen and the planer automatically corrects the head position – only one piece needs to be measured.
• Skip adjustments can be made in the fly.
• The machine is extremely robust and precise, a consequence of this is they can run fast – up to 1200 mpm. But many machines have been bought for their accuracy, reliability and ease of use, not for speed
• Uptime is extremely high, Gilbert guarantee 95% uptime!
• The machine is flexible, it can be used as a planer and a moulder – from complex profiles to decking to splitting and changeover is very quick, there are Gilbert owners that make 8-12 changes in a shift.
Gilbert also supplies the infeed and outfeed units;
Compact layout shown on drawing below. Only a one metre bridge between the feed table and planer. Will fit in an existing and small layout. Allows for more space after the planer to slow the wood down.
The feed table is a very sturdy and reliable unit with specially designed pineapples, to give positive feeding without tearing the wood and the slow down belts have automatic positioning for each section that is run by the mill and the optional addition of ‘chicken pluckers’ to hold the wood to the slowdown belt.
Pull Through Technology
Gilbert’s unique “Pull-Through” modular design is based on the foremost European technology that has been proven to reduce downtime significantly. Coupled with a range of options including the Gilbert Infeed Table, Powered Bridge and the Gilbert Automatic Cutterhead Positioning System the Gilbert planing system can be tailored specifically to any application and will significantly increase the quality of timber produced.
The planer runs with a gap between each piece of wood and wood can be observed traveling through the planer. Using the pull through technology each piece of wood is drawn through independently of each other regardless of the space between each piece. Benefits of this system include reduced stops in production and elimination of offset defects. This becomes particularly important when you consider the jamb-ups that occur in planers due to brittle wood from over drying and large knots, the conventional system of running one board into the next, causes breakage of timber in the planer. This results in significantly less downtime (95% uptime is common with Gilbert Planers.) Timber can be seen passing through the planer the operator is able to remove broken pieces at all times.
Fully Electric Planer
To ensure a steady speed and precision feeding, the Gilbert Planer is powered by an electric motorization allowing a high feed speed of up over 900m per minute. The feed rolls are powered by heavy duty drive shafts utilization self contained casing to reduce maintenance. This unique, environmentally aware system improves production, eliminates downtime and there is no need for hydraulic oil.
With such diverse benefits as low maintenance, elimination of offset defects and unequalled feed speeds the Gilbert Pull Through Planers are worth a closer look!
