• Blumis


  • Blumis is an individual electromagnetic sensor, that detects the movement of the traveller, detecting the speed of the traveller and the status of each yarn position.
  • Its special design, is developed especially and only for Zinser ™ 450 and 451 ring frame, and it is the first sensor for wool ring frames that works completely hidden, below the ring rail.
  • The sensor also reads the RPM of the traveller, detecting the spindles that are losing twist.
  • The status of the spindles is continuously monitored, and abnormal status (broken / low twist /disabled spindles) are signalized by bright red and blue L.E.D. situated in the corresponding spindle position.
  • A bright tower lamp with 4 different colour alarm, installed in each corner of the machine, alarm the operator showing the side of the machine that needs urgent piecing.

Special Features

  • No parts in movement: Less maintenance.
  • Electromagnetic Sensor: a proved technology that give good results with smaller costs.
  • The special design of the aluminium and pla­stic profile prevents the electronic pcb from aggressive oils and typical dust of the long staple spinning.
  • Linkable with most Pinterfani products and options. (roving stop; Eureka; LED display; etc)
  • No need for periodical maintenance
  • Available for 75 and 82.5 ring frame gauge, with J9,1 or 11.1 ring height.
  • Only for rings installed directly on ring plate; NOT WITH RING HOLDER


  • Dust doesn’t affect the performance of the sensors
  • L.E.D. Lights and sensor’s coils installed directly in PCB: ensure stronger system and easier maintenance.
  • From control unit Tbox (included), it’s easy to modify the settings of the sensors and analyse the sensors.
  • The only way to ensure 100% spindles without low twist
  • We only use high quality aluminium for Blumis’s casing. Rust never appears.
  • The tower lamps, combined with the individual sensor’s L.E.D, allow the operator to change completely the patrolling path, saving lost time and increasing operator’s performances.
  • The sensors are installed on the ring rail supports, allowing the operators to remove the ring rails exactly as without our sensor.  


BSF: Blumis Sensorfil TWO bright L.E.D installed for each spindle gives directly indication of the precise position where the problem is.

  • Red LED: yarn broken
  • Blue LED: yarn is losing twist.
  • Blue blinking: sensor is deactivated.

Thanks  to the system, operator can control more ring frames staying outside the machines.
Then he go first in the alley where more yarns are broken, avoiding the alley without breaks and reducing the piecing time.
