SF-180 Automatic Stitching Wire Flattening & Coiling Machine

From Round Wire to Finished Flat Stitching-Wire Coils in One Automated Process

The SF-180 Automatic Stitching Wire Flattening & Coiling Machine is designed for manufacturers producing flat stitching wire used for corrugated cartons, box closing and industrial packaging applications.

In conventional production, wire flattening and finished-coil handling may be carried out in separate steps. The SF-180 integrates the main operations into one coordinated production process.

The machine can automatically complete:

Wire Pay-Off → Wire Monitoring → Wire Flattening → Preset-Length Control → Servo Traverse Coiling → Automatic Tying → Automatic Coil Discharge → Next Production Cycle

By combining wire flattening, flat-wire coiling and finished-coil handling, the SF-180 helps reduce intermediate handling, repetitive manual work and unnecessary production steps.

==================================================
Higher Output per Operator
==================================================

For stitching-wire manufacturers, production efficiency depends not only on flattening speed but also on how much operator attention is required between one finished coil and the next.

Frequent material loading, coil removal, tying and other handling operations can limit the number of machines one operator can supervise.

The SF-180 is designed to automate these repetitive operations.

With Large-Coil Pay-Off

Under stable production conditions, one operator can supervise up to approximately 6–8 SF-180 machines when a suitable large-coil pay-off system is used.

Large incoming coils reduce the frequency of material replacement, while the SF-180 automatically performs coiling, tying and finished-coil discharge.

With Small-Coil Pay-Off

When smaller incoming wire coils are used, one operator can typically supervise around 3 machines because material replacement and wire joining are required more frequently.

For this reason, the pay-off arrangement is an important part of the overall production configuration and can directly affect labor efficiency.

==================================================
Integrated Wire Flattening & Flat-Wire Coiling
==================================================

Conventional Multi-Step Production

Depending on the existing production method, flat stitching wire may involve separate processing and handling steps such as:

Wire Flattening → Intermediate Wire Handling → Rewinding / Coiling → Manual Coil Handling → Manual Tying / Removal

This type of arrangement may require:

– More separate processing stations
– More intermediate wire handling
– More operator involvement between processes
– Additional floor space for separate equipment
– More manual handling of finished coils

SF-180 Integrated Production

The SF-180 combines the main production operations into one coordinated process:

Pay-Off → Wire Flattening → Servo Traverse Coiling → Preset Length → Automatic Tying → Automatic Coil Discharge → Next Coil

The result is a more integrated stitching-wire production flow with less intermediate handling.

==================================================
Automatic Coil Handling Beyond Basic Wire Flattening
==================================================

A high wire-flattening speed alone does not necessarily reduce labor.

The main difference of the SF-180 is that automation continues after the wire has been flattened.

Preset-Length Control

The required coil length can be set through the HMI.

The control system coordinates the winding cycle according to the preset production requirement.

Servo-Controlled Traverse Coiling

The traverse mechanism is servo controlled to distribute the flat wire during coiling.

This supports orderly coil formation and repeatable finished-coil production.

Automatic Tying

After the preset coil is completed, the machine automatically performs the tying operation.

This reduces the need for the operator to manually tie every finished coil.

Automatic Coil Discharge

After tying, the finished coil is automatically discharged from the winding position.

The machine can then prepare for the next production cycle.

Less Manual Handling Between Coils

The operator does not need to manually complete every step between one finished coil and the next.

This automated coil-handling cycle is one of the main reasons several SF-180 machines can be supervised by one operator under suitable production conditions.

==================================================
Stable Flat-Wire Forming
==================================================

Consistent stitching-wire production starts with stable wire entry and reliable flattening.

Carbide Flattening Rollers

Wear-resistant carbide rollers are used to cold-roll the incoming round wire into the required flat-wire profile.

The durable rolling surface helps maintain stable forming conditions during continuous production.

Adjustable Inlet Wire Alignment

The inlet round wire can be aligned horizontally with the center of the flattening rollers.

Correct wire alignment supports stable feeding and helps reduce off-center loading on the rollers.

Servo-Controlled Coiling

After flattening, the flat wire enters the servo-controlled coiling section.

Coordinated winding and traverse movement supports orderly and repeatable finished-coil formation.

==================================================
Typical Stitching-Wire Size Reference
==================================================

Wire Size: 16#
Inlet Round Wire: Ø1.65 mm
Outlet Flat Wire (W × T): 2.15 × 0.75 mm
Typical Material: Q195 galvanized / copper-coated steel wire

Wire Size: 17#
Inlet Round Wire: Ø1.60 mm
Outlet Flat Wire (W × T): 2.00 × 0.80 mm
Typical Material: Q195 galvanized / copper-coated steel wire

Wire Size: 18#
Inlet Round Wire: Ø1.45 mm
Outlet Flat Wire (W × T): 1.75 × 0.75 mm
Typical Material: Q195 galvanized / copper-coated steel wire

Wire Size: 20#
Inlet Round Wire: Ø1.20 mm
Outlet Flat Wire (W × T): 1.35 × 0.65 mm
Typical Material: Q195 galvanized / copper-coated steel wire

The above sizes are typical production references. Other specifications should be confirmed according to the customer’s inlet wire, required outlet dimensions and finished-coil specification.

==================================================
Process Monitoring for Continuous Production
==================================================

High-speed production requires stable wire feeding and controlled machine response when abnormal conditions occur.

The SF-180 therefore includes monitoring and control functions designed to reduce avoidable production interruptions.

Anti-Tangle Detection

The pay-off path can be monitored for abnormal wire movement, tangling or knotting.

When an abnormal condition is detected, the system can trigger an alarm and controlled stop to help prevent abnormal wire from entering the flattening section.

Wire-Break Monitoring

The machine monitors wire continuity during production.

When the wire path is interrupted, the control system supports an appropriate machine response.

Material-End Detection

The incoming material condition can be monitored so the machine can stop in a controlled manner before the wire is completely consumed.

This can help retain sufficient tail wire for connection to the next incoming coil.

PLC + HMI Control

A Xinje PLC coordinates the machine sequence.

Production length and operating settings can be entered and monitored through the HMI.
