Rider roll load variations affect wound-in tension which can affect roll quality and resulting in poor performance in downstream processes. These load variations result from hydraulic pressure swings which can be caused by either electrical issues and / or defective hydraulic circuit components. Detecting such anomalies can be challenging as...

Winders run different grades, each requiring a specific set of winding parameters (torque, nip , tension), to produce rolls with optimal structure and free from defects. The winding parameters are either selected automatically or manually by operators. Detection & Corrective Actions Tap for Bigger version of this image! Out of...
A reliable sheet tension control is an essential component for optimum winder operation and roll quality. Abnormal deviation in tension due to defective tension control is likely to go undetected at the mill as the variations in the wound-in tension are often only detected when rolls are consumed at the...
When several motors are used to drive an equipment section composed of several mechanically coupled rolls, loosing one motor will cause a redistribution of the load among the remaining motors. This can become an issue if the necessary load exceeds the remaining motor capacity. Detection Tap for Bigger version of...
Whether dealing with legacy or modern digital drives, it is what is being fed from the drive output to the motors that counts as this is what will affect the process and product quality.The quality of the drive motor current output relies on a good operation of the rectifier bridge...
Shifts in load cell calibrations or defective load cells cannot be detected in closed loop systems, since the control is continuously aligning the load cell feedback signal on the reference.

VP Operations
"By resolving most of our production problems through remote support, SPN Consultants managed to dramatically reduce our downtime and maintenance costs. For problems that require special attention, SPN's experts are always available to address issues."
Jean-François Poirier
Supervisor
"Just in the past year, we've saved over $220,000 in rejected paper rolls by monitoring our winder with SPN's solution, which consistently alerts us about potential issues that may impact the quality of our paper rolls."
Nathan Gallant
Reliability Engineer
"With the challenge of aging equipment, SPNs services provide us with constani reliable insight to effectively maintain the paper, winder and dryer machines, identifying the weak links and preventing critical problems before they even happen."
