The SCT.400 NEXUS electronic ball-winding machine is suitable to produce high-quality balls in wool, acrylic, mixed and fancy yarns, cotton and similar fibres from 150 to 500 grs with length from 20 to 36 cm.

 

It is equipped with the most advanced ball shape and pattern control ever built.

 

TECHNICAL FEATURES:

 

Number of winding positions: 12 and 16.

 

Multi-language programmable 9.7″ TFT colour touch screen operator panel where the following parameters can be set:

 

• Winding speed, adjustable from 50 to over 700 rpm.
• Beam movement (shape of the balls).
• Patterns and thread laying of the balls. The device is also able to change automatically ball patterns during the winding cycle to obtain more voluminous and softer balls.
• Pattern selection infinitely variable from 1:2,000 to 1:600,000.
• Weight of the balls.

 

All the parameters can be stored in 200 programs, so it is possible to recall them as needed.

 

The panel also displays useful messages for the operator, including:

 

• Alarm messages, chronology of the alarms.
• Status of Input and outputs of the PLC and the encoders.
• Functional messages.
• Real time working data.

 

Selectable languages: Italian, English, Spanish, Portuguese, Chinese, Russian, French, German.

 

• USB port: to download the database of ball programs on a USB key (pendrive), to have a copy and / or to be able to transfer the database to another ball-winding machine.
• Program Lock Key.
• Automation control via PLC with integrated motion control.
• Multicolour Tower lamp signalization.

 

The machine is also equipped with:

 

• Automatic opening and closing of the mandrels.
• Simultaneous calibration of the diameter of the mandrels.
• Automatic yarn cutting with tail-clamping device for the next cycle.
• Automatic yarn ends release device during the winding cycle.
• Beam movement controlled by motorized cylinder.
• Cone holder reel suitable for all types of cones with reserve positions.
• Yarn-cutter knives made of hardened K100 steel.
• Pneumatic yarn threading device into the winding flyers (one valve per flyer).
• Timing belt transmission.

 

Safety equipment according to EU and US safety regulations:

 

• Photoelectric safety barriers (front and rear operator detection), SIL3 Type 4, interfaced with safety relays.

Dimensions: see PDF file.

 

OPTIONALS:

 

• Conveyor belt driven by inverter.
• Pneumatical creel for easier unwinding of yarn in cakes.
• Yarn break detection device (BTSR IS3F sensors) with self-adapting system able to detect yarn presence in the flyer at cycle start and automatically exclude the sensor if yarn is absent.
• Electronic positive yarn feeder device.
