Top performance in diverse use scenarios

As Take-up Winder
Continuous yarn production/treatment processes.
As Assembly Winder
Continuous/discontinuous rewinding of one or several assembled yarn ends from creel-loaded supply bobbins with/without intermingling or rewinding from a driven spindle.
As Direct Spinning Winder
Implementation of winding positions into spinning plants for speeds up to 3,000 m/min. Also as a retrofit solution: replacement of manual winders in existing spinning plants.

Compact and modular design - Peak performance with minimum space

Your advantages

Design your own TWINSTAR II

For peak winding performance customized exactly to your needs


Bobbin push-off device with parking position

Bobbin push-off device with parking position

During automatic bobbin changeover, the finished bobbin is pushed into a parking position while the next bobbin is already being wound. Perfect for automated doffing and higher flexibility for manual doffing.

Yarn reserve

Yarn reserve

Adjustable yarn reserve with minimum yarn tail after automatic changeover.

NEW: Flexible Traverse

NEW: Flexible Traverse

You get full adjustability for: traverse width, bobbin shape, bobbin positioning and yarn reserve choice.

Pull roll (godet)

Pull roll (godet)

Godet per winding head pulling the yarn from the preprocess.

Winding direction

TWINSTAR II series provides a winding head assembly for q-wind direction as a standard while a mirror-inverted assembly for p-wind direction is available as an option.



Air entanglement of single or assembled multifilament yarns while the yarn length of several assembled ends is kept equal (low catenary effect) and the cumulative strength of the yarn is maintained.

Quality sensor

Quality sensor

Monitoring of yarn thickness to check for broken filaments and problems with material quality.

Customized yarn guide assemblies

With/without knot deflector and/or melt catcher.

Diameter monitoring/control

Online yarn diameter monitoring, with optional closed- loop system for control of the diameter regulated by the winding speed. Separation of the production whenever material leaves the tolerance range.

Double cam

Double scroll cam for two different traverse lengths.

Yarn cutter

Automatically controlled pneumatic cutting device per winding position provides a clear shear cut of yarns during start-up and refeeding processes.

Yarn suction device

Automatic yarn suction device per winding position for higher operator convenience during start-up and refeeding processes.

Winding head change connector

Easy maintenance unit with and without easy change connector (ECC), helps to quickly disconnect and remove the winding head for maintenance purposes.

Lifting loader

Lifting loader

Exclusive SAHM maintenance feature for secure, quick removal of the complete winding head.

NEW: Smart View

NEW: Smart View

Monitoring application to track the production of each winder.

Chill Unit | Easy Storage Doffer (ESD)

Chill Unit | Easy Storage Doffer (ESD)

Yarn cooling and relaxing chamber helps avoid residual shrinkage and preserve material properties.

Easy Storage Doffer enables automatic bobbin and tube changes and intermediate storage of finished bobbins.


The TWINSTAR II can be adapted to different handling systems. From Easy Storage Doffers for individual winding stations to fully automated robotic solutions for large and complex production lines.


Central process control unit (HMI touch screen) for input, display and storage of process and machine parameters.


Interface to DCS (Distributed Control System) or OPC UA data exchange system.

Remote support

Remote access and support for diagnosis and guidance during troubleshooting.

Ready for automation

Ready for automation

SAHM offers scalable automation solutions for TWINSTAR II winder lines ranging from an Easy Storage Doffer for single winding positions to AGV fleet integration with robotic options and temporary bobbin storage for lines with several winding positions.
