Full Digital Technology, Top Accuracy, High Flexibility


DIAPERFEEDER in a high precision measurement and control instrument providing a real time display of the exact yarn tension and guaranteeing, through an accurate adjustment, a constant tension feeding of the yarn itself in every working condition.


DIAPERFEEDER is fully programmable and can easily be adapted to any kind of yarn/fiber or tension adjustment and to any operating speed of the machine on which they are installed.

The data setting is easily done through a small three-button key-pad and a graphic LCD display. In normal operating conditions the LCD provides a real time display of the exact yarn tension (in grams) during the manufacturing process, the yarn consumption speed (LFA) (in m/min) and, in graphical form, both the average and peak values of the yarn tension.

Thanks to the BTSR 'Full Digital Technology', featuring a dual control on yarn feeding and yarn running speed, DIAPER FEEDER is able to guarantee absolute performance in terms of system acceleration/deceleration dynamics control with a very high resolution measurement capability (0.1 mm) of the yarn fed to the process.

Main Applicative Benefits

  • Fully programmable - easy parameter setting (Tension Profiler, % tolerances, ...) for diversified working conditions.
  • Fiber Constant Tension Control - high feeding tension values fiber control at very low running speed, without pretension
  • Constant yarn tension both when the machine speed changes and when the yarn packages gradually get empty
  • Best efficiency by eliminating the yarn breakage (tears and extratensions), and possibility of working at the highest speed offered by the machine
  • Drastic second-rate product reduction
  • Accurate yarn feeding speed measurement
  • Possibility of using the yarn up to the complete package emptying.
  • Machine efficiency improvement - A compact Solution easy and plug & play installation.

Main Technical Features

  • Programmable tension: 0,5gr. ÷ 1000 gr.
  • Yarn Feeding speed: up to 2.500 mt/min
  • Advanced Graphic Display for easy real time working parameters monitoring
  • Tension Profiler Function: yarn tension increment / decrement
  • Automatic function possibility during the working process phases.
  • TARGET Function: possibility to set a production target in meters with the relative automatic machine stop
  • Error tension alarms
  • IP54 protection degree, thus allowing to work with critical environmental conditions, like humidity, dustiness, etc.
