Cortex has developed a revolutionary way to maintain log control with the Modular Cam System. A common challenge with many chip and saw lines is log control. Even when the chipping heads are new - if an operational variable has changed (feed speed, log diameter, etc) and the heads are not in sync
with current settings, logs may tend to surge, or ‘shoot’ through the heads. This surging can cause band saw damage, poor board finish, and a host of other sub-par performance issues.
Traditional chipping head manufacturers will simply calculate the cam height based on the chip length (feed speed, RPM, knife count) and hope for the best. Some mills have been forced to spend thousands of dollars a month on replacing clamps in order to maintain log control. Others are stuck with
completely replacing the segments, a costly and time consuming project.
The Cortex Modular Cam system provides an adjustable height cam to compensate for wear, as well as adjust for a change in feed speed or chip length. Cam thickness is measured periodically to detect wear, and if needed, the cam can simply be shimmed out into specified height. Additionally, the cam can be lowered to compensate for longer chip length (faster speed). A Cortex service technician can monitor this cam height in order to maintain proper log control during regular service visits.
• Consistent log control
• Reduced costs on segments
• Versatility for an ever-changing operating environment
Segments include replaceable gullets and holders as well. The segment is not in the wear zone with these replaceable parts.
