A world of accessories

Ratera provides a wide range of useful accessories necessary for obtaining the desired final product and adapting to the needs of each factory.

  • A wide range of tensioners for multiple threads and tension control: Ceramic Discs for textiles, ball tensioners for coarse products, or electronic feeders for constant tension for very fine threads such as sutures, etc.
  • The touchscreen of the new winder is useful to adjust different variables, and the parameters entered are stored using recipes in the PLC, increasing speed and improving an easy use.
  • Cutting is both mechanical and electrical, depending on the fiber. There is an option for automatic insertion of clips to hold loose ends after cutting. Ideal for multiple monofilament strands.
  • Option for heads with independent traction and metering, to reduce product waste to practically zero.
  • Bobbins with the same number of meters.
  • Constant head speed or linear speed.
  • Ceramics and finishes for any type of fiber: Textile, Synthetic, Monofilament, Fiberglass, Carbon Fiber, etc. Taking care of the product is vital for good braiding.
  • Protection of the winding area as an option.

Solutions for all the bobbins

This winders are designed to complement Ratera braiding machines, from the smallest bobbins of Gauge 80 with dimensions of Ø39×110 mm to medium-sized bobbins of Gauge 140 with dimensions of Ø 78×280 mm.

  • Automatic cycles of 4 by 4 maximize efficiency.
  • Flexibility. Possibility to wind various sizes of bobbins on the same machine. For example, the ML-100 model allows winding bobbins from gauge 80 to gauge 115.
  • Customized heads for filling spools from other brands and sectors.
