1. Pain Points of Conventional Manual Reel Turn-up for High-speed Paper Machines

Reel turn-up refers to the operation of transferring running paper web onto a new empty spool when the pope reel reaches target diameter, to realize continuous winding. For manual reel turn-up under high-speed conditions, multiple practical bottlenecks appear.

Operator safety risk

Operators need to approach rotating rolls to guide paper tails during reel change. Mis-operation or untimely response may cause collision and mechanical injury. Safety hazards are prominent in high-speed production environments.

Heavy dependence on operator experience

Manual turn-up requires skilled coordination: judging timing, guiding paper web, avoiding wrinkles. Turn-up quality varies greatly among different operators. New staff face long adaptation cycles. Unskilled operation leads to failed reel change repeatedly.

2. What Is a Paper Tape Automatic Reel Turn-up System?

The paper tape automatic reel turn-up system is special automatic equipment for the reel section of paper machines. It uses dedicated paper tape as the medium, cooperating with pneumatic actuators and PLC automatic control logic, to finish paper web transfer to new spool automatically. It replaces manual tail-guiding work.The whole set integrates electric control, pneumatic execution, paper-tape storage and delivery mechanism and automatic turn-up beam. It is not universal plug-and-play equipment; it needs matching according to reel-up mechanical structure, paper varieties and machine speed to achieve stable performance.

3. Working Principle of Paper Tape Reel Turn-up System

The system is designed for automatic reel change at paper machine reel section. Its complete action sequence is as follows:

Step 1-Paper tape standby preparation 

The paper-tape magazine stores special turn-up paper tape. The paper-tape conveying mechanism automatically takes paper tape out of magazine and transports it along guide rails to pre-set standby position, waiting for turn-up trigger signal.

Step 2-Receive reel-change trigger signal 

When the pope reel reaches the set diameter, paper machine sends turn-up trigger signal to the system through electrical interface.

Step 3-Paper tape delivery and attachment to new spool 

Upon receiving the signal, the mechanism pushes the pre-positioned paper tape forward, and attaches the paper tape onto the surface of standby new reel spool.

Step 4-Synchronous web cutting and web transfer 

The control system synchronously executes paper web cutting action. Guided by the paper tape, the running paper web is quickly transferred and adheres to the new spool.

Step 5-Complete reel change and return to standby status 

The new spool starts winding paper web. The whole turn-up action is completed in an instant. The mechanism resets automatically and enters standby state for next reel-change cycle. The full process minimizes manual intervention, shortens reel-switching time and reduces paper broke loss.

4. Application Scope and Adaptability

Most running paper machines can complete field-based transformation. Need to verify installation space, reserved signal interface of original reel-up and compressed-air conditions before implementation.

5. Key Parameters for Selecting a Paper Tape Reel Turn-up Solution

Paper machine reel-up structures differ greatly. One-size-fits-all solution cannot guarantee stable operation. The following parameters shall be confirmed before engineering design.

Paper machine operating speed

Machine speed directly affects paper web stability. Under high-speed conditions, paper web flutter, tension fluctuation will affect turn-up success rate. The system design should target actual running speed instead of only theoretical design speed of paper machine.

Paper grade and basis weight

Paper stiffness, tensile strength, surface property differ for thin paper and heavy-weight paperboard. These factors decide the selection of paper-tape specifications, pneumatic thrust, cutting timing and action speed of turn-up beam.

Reel-up mechanical structure

Need to confirm spool size, reel-up layout, movement stroke of existing reel-up mechanism. Check space for installing turn-up beam, paper-tape box and control cabinets, and avoid interference with original equipment.

Compressed-air supply condition

The system relies on compressed air to drive actuators. Confirm air pressure, flow rate, air quality and stability of on-site air source. Insufficient air supply will lead to unstable action and reduce turn-up success rate.

Electrical signal interface

Confirm signal interconnection mode between new system and original paper machine control system, to realize reliable receiving of reel-change trigger signal and feedback of system status signal.

On-site installation space

Retrofit projects often have limited space. Evaluate frame occupation, walk-way, maintenance space, roll-changing operation space to ensure equipment installation without interfering with daily operation and overhaul.

6.Core System Components
