Turret WinderCost-effective non-stop winding with winding shafts up to 3,000 mm working width
1 / 3
The automatic turret winder ATW-E is the cost-effective variant with winding shaft support. Its main application is in printing lines as well as in paper finishing and laminated film processing. Other applications where web-form material must be continuously wound are also easily handled. The machine concept can be optimally adapted to individual requirements and perfectly integrated into new or existing production lines.

Applications
The SOMATEC ATW-E automatically winds virtually all web-based materials — the economical standard solution with winding shaft support for printing, coating and converting lines.
Film converting — Packaging films, shrink films, technical films and barrier films
Nonwoven processing — Nonwovens for hygiene, medical and filtration products
Paper and board processing — Coating, lamination and printing lines
Adhesive tape industry — Feeding of tape substrates, release liners and self-adhesive webs
Flooring production — PVC flooring (LVT, vinyl), carrier webs and decorative films
Artificial leather production — PVC and PU artificial leather webs
Technical textiles — Geotextiles, filter materials and coated textiles
Roofing membranes & construction films — Bitumen sheets, vapor barriers and sealing films
Why the ATW-E?
The ATW-E is the cost-effective variant with winding shafts, offering a wide range of equipment options for perfect winding results. Selectable contact or gap winding, motorized rider rolls and antistatic equipment ensure optimal quality. The automatic roll change takes place at full production speed — depending on the system with core preparation (TAC, up to 600 m/min) or without (NTC, up to 350 m/min). The machine concept can be individually adapted to your requirements.
Typical Configurations
Converting line: SOMATEC UW-E unwinder + ATW-E winder with splice synchronization for loss-free non-stop operation
Paper finishing: ATW-E with NTC system for roll change without core preparation and roll removal cart with up to 25 m travel
High automation: ATW-E with in-line slitting unit, roll support roller and automatic finished roll and winding shaft handling

Frequently Asked Questions
What is the difference between unwinder and winder? — The unwinder feeds the raw material into the line. The winder (rewinder) takes up the finished product at the line end. Both are winding machines but with reversed function.
What does automatic turret winder mean? — An automatic turret winder changes the winding position on-the-fly — without stopping the line. When a roll is full, the turret automatically swings and the next empty core takes over. Essential for continuous production.
Which industries is the ATW-E suitable for? — Adhesive tape production, nonwoven processing, film coating, packaging converting, technical textiles, artificial leather production and flooring finishing. Wherever continuous winding under controlled conditions is required.
Can the ATW-E be integrated into existing lines? — Yes — SOMATEC turret winders are available as new installations and as retrofit solutions for existing converting lines. SOMATEC assesses the installation situation and coordinates the technical interface.
How is the right machine selected? — SOMATEC analyzes your process: material type, web width, line speed, roll weight, web tension requirements and space constraints. Then SOMATEC recommends the appropriate variant and supports the project through to commissioning.
