Creating an Effective Corrugator Maintenance Schedule

Unplanned downtime is the enemy of corrugator profitability. A well-designed preventive maintenance program keeps your line running and prevents costly emergency repairs.

Daily Maintenance Tasks:

• Clean adhesive applicator rolls and pans

• Check web tension and alignment

• Inspect and clean corrugating roll surfaces

• Verify adhesive viscosity and temperature

• Remove paper dust from critical areas

• Check oil levels on lubrication systems

Weekly Maintenance Tasks:

• Deep clean glue systems and tanks

• Inspect doctor roll gaps and condition

• Check belt tension and condition

• Verify pressure roll settings

• Inspect steam traps (for traditional lines)

• Test safety systems and emergency stops

Monthly Maintenance Tasks:

• Full corrugating roll inspection

• Check and calibrate temperature sensors

• Inspect hot plate surfaces

• Verify cutter knife condition

• Check gear oil levels and condition

• Review and update maintenance logs

Quarterly/Annual Tasks:

• Major roll inspection and grinding

• Full electrical system inspection

• Comprehensive calibration of all sensors

• Structural inspection of frames and supports

• Update spare parts inventory

Documentation and Tracking:

Maintain detailed records of:

• All maintenance activities performed

• Parts replaced and their service life

• Unusual observations or conditions

• Correlation between maintenance and quality issues

Many plants now use CMMS (Computerized Maintenance Management Systems) to track schedules and history.
