WINDER / ROVING / ROTOR / RING
The new machine, manufactured in Qingdao, is in position to offer to the local market the updated technologies together with enhanced technical features, developed in compliance with the international markets requirements.This automatic winder summarizes all the expectations required by the local as well as by the international markets, thanks to various innovations in terms of package formation quality and splicing technology, to cover any materials and yarn types, including yarn with elastomeric thread, either single core or duo core, as well as siro spun yarns.
Electronic anti ribboning device
The drum speed is controlled by the machine PC, and changes its value (electronic anti patterning system) only at the pre-set package critical diameters.
• The drum speed variation and frequency are set on the machine PC.
• The system operates also during the acceleration after
the splicing cycle.
• Patterns on the package are minimized for a better use in the downstream processes.
• Axial displacement (optional) can also be used for dyeing package in combination with the electronic anti patterning.
Flexible cycle
Thanks to the individual motors and PC, the splicing cycle is automatically made,as per the actual requests of the splicing steps, improving,as consequence, the efficiency and production of the winder.
Consequently:
• Greater productivity
• Consistent package quality(no presence of double yarns or yarn scrambling)
• Power and compressed air savings because unnecessary splicing cycle are avoided
• Minimum wear of the parts
• Minimum yarn waste

Computer Aided Tension
The winding tension is detected continuously by the Tensor, which interacts with the yarn tensioner device, through the machine PC, in order to adjust the load on the yarn as required. The Tensor, being positioned just before the drum detects on line the real winding tension. The sensor does not have any movable parts and performs also as “antiwrap system”.
Tensorflex (standard)
In presence of elastomeric yarn blended with wool/cotton the tension values must be diversified during the package formation to ensure a perfect shape.
--------------------------------------------------------------------------------------------------------
Optimised acceleration curves
Package start with yarn deposit control Acceleration can be set via the computer. The operator sets the optimum acceleration each time according to the work parameters (count and material, waxing, etc.) thus allowing a perfect drive of the package with a regular deposit of the yarn.The computerised control system automatically adapts the acceleration ramp as package diameter varies.
--------------------------------------------------------------------------------------------------------
Booster
The device that adjusts itself at a constant distance from the nose of the tube, combines its action with the square section balloon breaker and significantly modifies the shape of the balloon, drastically reducing unwinding tension. This effect, also combined with the Tensor action, contributes to a considerable reduction in winding tension. During splicing, the Booster, coming into contact with the nose of the tube, acts as yarn antikink and economiser.
--------------------------------------------------------------------------------------------------------
Uniform yarn tension and waxing
Uniform yarn tension and waxing
The motorised yarn tensioner, with centralised adjustment via the Computer, is a guarantee of control uniformity with minimum yarn stress. Large, oscillating pressure washers for a constant, effective control.
Waxing unit (optional)
The yarn is waxed with a positively driven adjustable deflection device that guarantees waxing uniformity. Air jets keep the yarn tensioner and waxing unit free from dust.
Clearing logic
The machine is equipped with the Loepfe model ZENIT, totally integrated with the Polar process logic embedded in the machine PC with 15” screen, in a way that each single head becomes a technological laboratory to ensure the total quality of the wound yarn.
• Splice control
• Long defects
• Repetitive defects
• Foreign fibres (optional, in presence of electronic clearer model ZENIT FF).
Defects due to yarns with off-standard hairiness that are intercepted by the clearer, are automatically removed from the package. Polar flexible cycle minimizes machine production losses due to these “quality cuts”.
--------------------------------------------------------------------------------------------------------
Controlling the winding process
All parameters of the winding process are controlled by the Computer: • yarn quality • package quality
• production quality
• control of all peripheral units
• energy consumption.
The Computer has a large touch screen and an USB port. The data are displayed in a descriptive and graphical form. Ethernet interface for connection to higher level information systems. The peripherals’programme can be updated directly on the PC (also with remote loading).
Spindle Monitoring System
Each winding head is equipped with an alarm monitoring system. The operator is notified in real time of the ongoing alarm. Each spindle indicates technological as well as functional alarm.
