Rewinder

Supertek's automatic rewinders or rewinding machines consist of unwinders or pay-offs and winders or take-ups. By using modular, intelligent units (smart winder units), compact, powerful rewinding systems can be configured. Our rewinding machines are ideally suitable for precise unwinding, winding and rewinding very thin, delicate wire, flat wire, fibre glass, fibre optic cables, fibres, silk, film, solder, filament etc.

Rewinding machines are available in different versions for different spools and spool sizes with rpm, speed, position, length and tensile force control. Highly accurate tensile force and tensile stress control of the unwound winding material is achieved by the modular integration of the patented electromagnetic dancer on the unwinder. Wire brakes or wire tensioners are thus a thing of the past.

Winders on rewinding systems consist of fully electronic, highly accurate laying systems with which different types of winding can be performed for different spool types. So that the product to be rewound always runs straight, the winder and the unwinder can be fitted with a traversing spool drive or a multiwinder in other words. In this version a contactless overrun control always keeps the product to be unwound on the traversing unwinder in a required position so that even flat wires and other materials can be coiled up, rewound and wound in short distances.
Depending on the use case and the customer's requirements, rewinding machines can be fitted with different systems, such as annealing furnaces, dyeing plants, extruders, cleaning channels, diameter measurements, lump detectors, straighteners, straightening equipment, marking systems, cutting equipment, sorting functions, memories etc.

For many wound materials, e.g. for flat wires, tapes, films or for unwinding with short distances it is important that the product is always managed on one line.
Winders with additional traversing coil drives, for example the MW class of multiwinders, can move the coil in the axial direction (traversing type) as well as in a rotating movement so that the unwound material can be unwound at a fixed transfer position perpendicular to the coil.
As far as unwinders are concerned, Supertek offers a sensor-controlled overrun control that ensures that the product is always unwound at right angles to the traversing coil in a line. This avoids, amongst other things, fluctuations in tensile force even in the most delicate range and the products are less stressed.

Rewinding machine with unwinder, wire straightener, rewinder
Unwinder, wire straightener and rewinder can be used individually or in combination as a rewinder.
Unwinder with tension controller and lump monitor, operation separately with CMC or in combination via touch screen of the rewinder.
Wire straightener with optional diameter measurement.
Winder with traversing feeder for coils with high loads and operation with HMI or touch panel and software SUMMIpro.

 

The rewinder can be operated via different HMIs using serial data communication.
Using Supertek's touch panel solutions with SUMMI PC-based software is a convenient solution for setting and monitoring the parameters.
Obviously, operation, monitoring, formula management and data saving can also be performed by another manufacturer's PLC or HMI, such as Siemens, Beckhoff or Allen-Bradley, etc.

Advantages of Supertek rewinders compared with traditional systems:

  • Intelligent, modular units
  • Digital specification of parameters, e.g. tensile force, laying parameters etc.
  • System can be networked, digital communication
  • Rpm, speed, position, length and tensile force control can be selected
  • Highly accurate tensile force control 
  • Digitally adjustable tensile force with high tensile force range at high resolution in mN steps
  • Increased quality, gentle, stress-free processing
  • Ideally suited to the most delicate wires, fibres, glass fibre and other delicate wound materials.
  • Reproducible, digitally documentable parameter settings (track and traceability for consistent traceability of the line tensile force, speed etc.).
  • Fully electronic system (no pneumatics or compressed air).
  • Process-dependent adjustment of the tensile force, speed, position etc. possible at any time
  • Suitable for dynamic processes
  • Easy to integrate other units, such as annealing furnaces, dyeing plants, measuring devices, memories, straighteners, extruders, marking, cutting tools, etc.
