Proven Expertise Across the Paper Mill Process
For over a century, TMEIC has delivered complete drive, control, and modernization solutions to the pulp and paper industry. Our experienced engineers provide cost-saving technologies across the entire mill—from tissue machines and calender rolls to winders and off-machine coaters. These systems are tailored to meet the unique demands of each application and paper type, including coated paper, fine papers, fiber board, newsprint, and more.
Reliable Drive Systems and Modernization for Long-Term Performance
With over 1,000 drive systems installed globally, TMEIC designs, tests, and commissions coordinated drive solutions built for efficiency and reliability. Whether supporting a new installation or modernizing aging equipment, our systems improve production, reduce downtime, and extend equipment life. From headbox to winder, our high-performance motors, drives, and automation hardware help paper mills meet the increasing demands of today’s global market.
Applications
Recent paper machines utilize AC drive technology. The latest newsprint paper machine has line data of 1700m/min speed, paper width 9000mm, and the total drive capacity of about 20,000kW. For larger paper machines, each motor capacity exceeds 1000kW, so large capacity single drive inverters are being applied.
In the case of a large sectional paper machine drive system, beyond 1000kW capacity, medium voltage (1200V) IGBT inverters are applied. If the capacity is below 1000kW, 400V IGBT inverters are applied.
Common converters provide DC power to these inverters.
For paper rolls and small capacity motor applications, a multi-stage structured inverter is utilized to save space. The interface between programmable controllers and inverters is via fiber optic transmission.
TMEIC provides innovative solutions for paper machine controls. TMEIC offers sectional control systems to satisfy paper and machinery requirements including monitoring systems, improving operational efficiency and product quality, tension fluctuation control, speed draw tracking systems and so on.

AC drive systems provide nearly maintenance-free control of a winder. When the AC drive systems switch to regeneration from powering, or from regeneration to powering, the uncontrolled states near zero current of a conventional DC drive are eliminated. Operation at stall tension is limited in a DC Drive System because a DC motor is damaged if full current is applied at zero speed. AC drive technology does not have this type of restriction. AC drives can provide 100% current at zero speed without damaging the motor.
TMEIC provides drive systems and monitoring systems for various kinds of winding machines characterized by machine suppliers. Our drive system includes load sharing control between drums, residue unwinder (parent’s roll) diameter control, taper tension control, and automation system for sheer repair so that our customer can get the optimal product qualities.
Systems Applications
- Two drum winder
- Single drum winder
- Center roll winder
- Rereeler
- Finish winder (winder products)
- Salvage winder
A centralized monitoring system is necessary to reduce a startup period, to minimize MTBF and to increase uptime. The integration of Process Control, Production Management and Quality Control systems achieves high production efficiency and consistent product quality.
TMEIC provides electrical drive systems, instrumentations and computer control designed for Pulp and Paper applications. TMEIC supplies a C.I.E. (Computer & I.E.) integrated control system and I.E integrated control system surpassing customers’ requirements.
