Paper and packaging line spare parts support pulp preparation, paper-machine operation, web tension, cutting, printing and end-of-line packaging equipment.
| Application | What the automation system does | Typical spare parts |
|---|---|---|
| Pulp preparation, furnish and dosing | Controls furnish ratio, flow, level and chemical-additive quantity. | PLC/DCS, analog modules, flow meters and VFDs |
| Paper forming, pressing and drying | Coordinates section speed and adjusts steam pressure, temperature and related process conditions. | Controllers, I/O modules, drives, temperature and pressure sensors |
| Paper quality monitoring | Measures basis weight, moisture and other quality indicators to provide process feedback. | QCS measurement and control modules |
| Rewinding, unwinding and slitting | Controls roll speed, tension and cut length to reduce web breaks and uneven winding. | Tension sensors, encoders, servo drives and motion-control modules |
| Printing and registration | Coordinates web transport and print position so artwork aligns correctly. | Registration sensors, encoders, servo systems and controllers |
| Cartoning, case packing and sealing | Sequences feeding, folding, gluing, packing and closing operations. | PLC, DI/DO modules, photoelectric sensors and servo drives |
| Conveying, sorting and palletizing | Coordinates transport, counting, diverting and stacking of finished products. | PLC, VFDs, sensors and robot-control components |
As roll diameter increases, an unmatched drive response can pull the web too hard or wind it too loosely. A tension sensor measures the process and the controller compares it with the target before the drive adjusts motor torque or speed.
A registration sensor detects the mark, the controller calculates the error and a servo system corrects feed or knife position so the finished cut aligns with the printed design.
Procurement purpose: These spare parts replace failed controllers, I/O cards, drive boards, power supplies and communication modules, reducing line stops, web breaks and packaging waste.
Web-control example
As line speed or roll diameter changes, the control system adjusts drive speed and torque while feedback devices confirm position and tension. A replacement drive, encoder, motion module or remote I/O card must match the installed architecture and machine recipe.

Where spare parts fit
Exact-model replacements support continuity, synchronized motion and repeatable packaging quality across legacy and current equipment.
01 · Motion
VFDs, servo drives, motors, encoders and motion modules coordinate rollers, cutters, folders and packers.
02 · Process
Controllers, power supplies and distributed I/O collect sensors and execute machine sequences.
03 · Quality
Registration sensors, web guides, industrial networks, HMI and inspection interfaces support production decisions.
