Dimensional Control Engineering for
Pulp and Paper
Alignment of rollers, planing tables, calenders, and wood chippers. Eliminate sheet breaks, vibrations, and premature wear of the blankets.
THE CHALLENGE OF SOLID LINES
The pulp and paper industry operates with gigantic machines running at full speed (24/7).
Under these extreme conditions, even minor deviations in parallelism or leveling can have severe consequences:
- Downtime and losses: Frequent sheet breaks and premature wear of felts and screens.
- Loss of quality: Variations in paper basis weight, roughness, and moisture content.
- Mechanical damage: Excessive vibrations that destroy bearings, roll heads, and gears.
Critical Solutions and Applications
Wooden Deck, Digesters, and Boilers
Chippers and Peelers Geometric calibration of shafts and bases to reduce vibrations and standardize chip size.
Digital Twins (As-Built)
3D scanning of recovery boilers and digesters for expansion projects and analysis of thermal deformations.
Stainless Steel Piping (CIP/Mass)
Inspection and assurance of assembly without mechanical stress for perfect flow.
Pulp and Paper Machines
Drying Rolls and Cylinders Geometric inspection of parallelism and leveling in the press, drying, and calender sections.
Smoothing Tables and Headboards
Precise adjustment to ensure uniform distribution of the pulp slurry.
Rewinders and Cutters
Alignment of shafts, drive rolls, and blades to prevent wrinkling and tension variations.
QUALITY ASSURANCE AND OEE IMPROVEMENT
Ensure compliance with the tolerances recommended by leading manufacturers (OEMs). Your plant will reduce paper breaks, extend the service life of felts and bearings, and achieve maximum operational efficiency (OEE).
WHAT SETS US APART: ALIGNMENT OF LONG SECTIONS
Maintaining precision in machines hundreds of meters long requires measurements that account for structural deflections and thermal expansion.
Roller Alignment
Tecnimex performs real-time alignment of rollers and structures during scheduled shutdowns, providing precise guidance so that the maintenance team can take swift action.
