Even on new machines there is always room for improvements. On this page you can read about different ways Cobra Technical Services is improving the performance of the high speed Gilbert Planer and Feed- Table. These findings have come by working close with certin mills who wanted more out of their performance. if you need more information not provided on this page please give us a call.
The tensioning and positioning of the planer rolls and the feed table rolls are just another area we can improve on the Gilbert planer Lines. We’ve noticed many of these machines are getting inconsistent tensioning forces on lumber, starting at the feed table, through the planer. This is due to pressure intensification in the air bag. This is also causing the position cylinders to retract not remaining in the required set position. This is more apparent with short lumber and a high piece count. Cobra tech has a upgrade kit that takes care of this issue. It is designed to give the top rolls a more consistent tensioning pressure at the same time, generates less shock, wear on the bearings, rolls, and shafts. And most importantly increased productivity!
Upgrades for the Gilbert Feed-Table
Upgrades for the Gilbert Planer
A few things we have noticed the last few years are, some mills have troubles maintaining a constant gap at the feed table, along with too much fiber being torn out. This is very critical area with the Gilbert planer because it causes break-ups, abuse to the planer and detracts from the ability to control the lumber landing on the landing table.  What we have done is to design and install new pineapples and bed rolls just for this machine. They have improved production by maintaining a better gap, tear less fiber and work together as one. In most cases the feed table speed will need to be slowed down due to the efficiency of our new designs for these Gilbert feed tables. 

The tensioning and positioning of the feed table rolls are just another area we can improve. We’ve noticed many of these machines are getting inconsistent tensioning forces on lumber, starting at the feed table, through the planer. This is due to pressure intensification in the air bag. This is also causing the position cylinders to retract not remaining in the required set position. This is more apparent with short lumber and a high piece count. Cobra tech has a upgrade kit that takes care of this issue. It is designed to give the top rolls a more consistent tensioning pressure at the same time, generates less shock, wear on the bearings, rolls, and shafts. And most importantly increased productivity!
Cobra Technical Services also offers an option to upgrade the top roll pneumatic/mechanical positioning cylinder to a system that is fully automated. This new system gives the operator the ability to independently position each roll to a predetermined set point with a touch of a button. These systems can be set up on a product recipe menu, controlled by servo or a less expensive, analog system. To find out more about what we are doing to increase the productivity of the Gibert feed-tables give Bill Jeson or Kevin Jenson call or email at
With the Gibert planer bed rolls we notice a lot of slippage and hesitation due to the design of the rolls. One way we helped increase the over all uptime and production with the planer was to rework the out feed rolls. We install top and bottom rolls with a texture that doesn’t mark or tear the wood, but most importantly pulls the lumber through the planer. This is eliminating the lumber hesitation problem, decreasing break-up and increasing planer uptime. 

Just like the feed table, the planer has the same problems: inconsistent tensioning forces due to pressure intensification in the air bags. This pressure intensification causes the position cylinders to retract, not remaining in the required set position as well as creating inconsistent forces. This is more apparent with short lumber and a high piece count. Our upgrade kit design gives the planer a consistent tensioning required to achieve optimum performance. This design also generates less shock, wear on the bearings, rolls, and shafts. Most importantly it results in increased productivity!


Cobra Tech offers mills an opportunity to optimize the Gilbert planer. This optimization package takes the top roll pneumatic/mechanical positioning cylinder and replaces it with a hydraulic/air system. This converts the manual adjustments over to independent positioning, where each rolls position and tensioning is controlled with a touch of a button. These systems can be set up on a product recipe menu, controlled by servo or a less expensive analog system. The Cobra kit for the Gilbert planer improves production by reducing break-ups, requiring less setup time, decreases shock, and produces a smooth flow of lumber through the planer.
