Water-Jet Turn-Up System

A fully automatic, non-contact water-jet turn-up system for all paper grades — compatible with conventional tape and pneumatic-assist turn-up equipment, delivering over 99.9% turn-up success rate and dramatically less reel-spool broke and spool damage.

Product Overview

Installed above the reel drum, the Tecno Turn Up System uses a servo-driven carriage carrying the cutting water jet to cut the sheet at high speed, instantaneously transferring the sheet from the parent reel to the new core at full speed — turn-up without stopping the machine.

Non-contact water-jet cutting produces a perfect tail edge, and flexible turn-up modes adapt to any paper grade and machine speed. The system works alongside conventional tape or pneumatic-assist turn-up equipment, and can also be specified as the standard turn-up solution for new machines.

How It Works

One Turn-Up, Step by Step

Turn-up principle diagram — Turn-up principle: the jet travels at high speed from the web centre outward to both edges, cutting a V-shaped tail that transfers to the new core

System Composition

Five Core Units

Traversing Beam

Servo-driven cutting nozzle slices the web at high speed; trajectory, speed and starting point are precisely controlled.

High-Pressure Pump Unit

Advanced air-driven intensifiers generate ultra-high-pressure water with long-term pressure retention — turn-up is available even during a sheet break.

High-Pressure Water Valve Cabinet

The distribution valve cabinet precisely controls the firing timing of the water jet with millisecond precision for consistent turn-ups.

Sealant System

The air-driven intensifier sealant pump holds pressure over long periods; combined with high-pressure dripless sealant valves, it precisely controls spray coverage and sealant consumption to secure every turn-up.

Control System

Connected to the paper machine DCS for fully automatic turn-up with no operator intervention.

Technical Advantages

Why Water-Jet Cutting

Reliable Turn-Up Efficiency

High pressure retained over long periods — turn-up available even during sheet breaks; millisecond-level program control delivers over 99.9% turn-up success rate.

Independent of Speed & Grammage

Ultra-high-pressure water carries enough energy to cut any sheet; diamond nozzles offer unmatched wear resistance and tiny orifices use minimal water per turn-up without disturbing production.

Less Spool Broke

Cutting speeds up to 12 m/s minimize spool broke; the cut tail lies flat on the spool — no folding, no nip marks.

Less Parent-Reel Damage

On wide machines, chevron tails can shatter at high speed and throw debris into the reel, causing breaks or defects — the edge sealant system solves this effectively.

Customer Benefits

Very Short Payback Period

✓ Turn-up success rate above 99.9%

✓ Less spool broke

✓ Less parent-reel broke

✓ Flat full-width reel — no nip marks, no glossy spots

✓ No frayed tail edge

Thick, curled spool broke produced by conventional turn-up

Case Study

Turn-Up Units Idle for 6 Years, Back in Service

Five 5600 mm high-speed tissue machines at a large tissue mill abroad had turn-up units out of use for over six years — restored one by one inside existing production stops.

CASE 02 · TISSUE · TURN-UP

Water-Jet Turn-Up Restored on Five High-Speed Tissue Machines

Invited by management, we surveyed the site in June 2026 and proposed the recovery plan on the spot. Equipment arrived within three months, ~60% of hardware was replaced and programs re-optimised, and all five units were restored during 1–10 hour production stops — accepted by the customer.
