SS+ Filament Winder

Small-Scale Production


The SS+ model is a standardized filament winder with all the benefits of our standard product line: optimized price, reduced lead time and trusted reliability. The machine may be customized and automated to any level of customer needs.


The SS+ is a compact, accurate, affordable three or four axes machine that is suitable for bottle or tapered part manufacture. The winder, table and control cabinet are integrated together to bridge the gap between laboratory and light production needs.

Servo Tensioning (ST2) Creels

An innovative and compact tensioning creel developed for high-speed and accuracy. The configuration of the guide rollers reduces stringer wrap-ups and fuzz. The standard ST2 can hold up to sixteen 9-inch diameter bobbins in an 82”x72”x40” footprint. The system can be customized and is compatible with towpreg and wet winding systems.

Wet Winding Drum Baths

ETC’s wet winding drum resin bath is a small scale resin bath ideal for the SS and SS+ winding machines. A 3.5” wide drum can handle up to 6 tows and a 1 liter resin pan reduces resin waste for small parts or R&D work. Available as a dip-style or roller-style bath.

Wet Winding Dip Resin Baths

Provide resin for up to 60 tows with ETC’s Dip Resin Bath. Adjustable drag bars and squeegees provide resin content control. Ideal for applications requiring wide fiber bands or operations that use center-pull spools.

Delivery Systems (Towpreg & Wet Winding)

Modern filament winding is all about delivering fiber where it’s needed. ETC’s delivery systems delivers fiber from the tensioner to the delivery head, minimizing contact points and maximizing control. Each delivery system is customized for facility layout, fiber type, and number of tows.

Towpreg Delivery Heads

ETC’s towpreg delivery head provides the same level of control as the wet winding head but with all rolling contacts to work with today’s advanced towpreg fiber systems. Each head is configured for a specific tow width and number of tows.

Wet Winding Delivery Heads

ETC’s wet winding delivery head allows precision fiber control as it is placed onto the mandrel. The standard configuration provides flat bars, a comb and a D-ring to adjust the fiber band width and thickness. Custom D-ring radii, pin count, pin spacing and additional fiber band adjusting options are available to meet customer’s needs.

Tape Tensioners

Give any ETC filament winding machine the ability to place shrink tape, veil or other spooled materials onto your mandrel. Tapes up to 3” wide can be placed with the same accuracy as fiber and with tensions up to 20 lbf.

Safety Fences

Acts a physical barrier around a workcell to keep operators safe from moving machinery. Safety fences can include interlocked doors for workcell access and be combined with Light Curtains and Foot Controls for customized safety needs.

Safety Light Curtains

Light curtains provide additional operator safety to any ETC winding machine. Each system is customized to protect hands, limbs or bodies from touching moving components inside the work cell. The machinery will stop immediately when a beam is broken, ensuring a safe work environment.

Safety Control Systems

Allow operators to maintain hand contact with the mandrels for tie-on/cut-off or placing local reinforcement while still being able to rotate the mandrel (forward and reverse) or stop it immediately as needed with foot operation.

Tailstock Chucks

Solidly support mandrels with the addition of a tailstock chuck. Ideal for unbalanced mandrels or delicate mandrels that may not withstand the axial force of a live center. The chuck is mounted to a standard Morse Taper and can be swapped with the tailstock live center for mandrel supporting flexibility.

Filament Winder Casters

Turn ETC’s line of small-scale filament winders (SS, SS+, SM) into portable winders by adding rolling casters. Ideal for lab use or facilities with limited floor space.
