Yarnmaster PRISMA
The new YarnMaster yarn clearer generation PRISMA astonishes everyone with its innovative fusion of sensor technologies.
The YarnMaster PRISMA world has a new integrated function: the MillMaster TOP management system for analysing and optimizing yarn quality.
A WORLD OF SENSORS
YarnMaster PRISMA combines established sensor technologies for the first time in one device.
- Optical Infrared ( D )
- Mass ( M )
- Optical RGB ( F )
- Triboelectric ( P )
This world first sets the benchmark and increases the productivity and efficiency.

A WORLD FIRST
DM SENSOR – DUAL MEASUREMENT FOR BASIC CLEARING.
Two dominant sensor technologies are integrated into one single sensing head.
This unconventional approach to use an optical and a mass sensor, functioning in perfect harmony, offers unprecedented possibilities and new levels of precision in yarn clearing.
With the intelligent fusion of the two sensor technologies, all technology-based advantages of both sensors are at your disposal and consolidated for your advantage.
YarnMaster PRISMA yarn clearers backed with DM sensor technology – ready for any challenge and ensuring an economic production without compromising on quality!

A WORLD OF COLORS
RGB F-SENSOR – THE FULL SPECTRUM OF LIGHT.
YarnMaster PRISMA takes once again the leading role in foreign matter clearing.
The all-new RGB F-sensor illuminates the yarn in the full spectrum of light.
Enabling so the recognition of the smallest shade and glossiness differences in any type of yarn and color and mixtures thereof.
Thus, a today required new milestone for contamination control during winding is set.

A WORLD OF UNIQUENESS
P4 SENSOR – THE INVISIBLE BECOMES VISIBLE.
The reliable detection of white and transparent polypropylene is a most difficult task in yarn clearing and requires a creative solution!
- Mastering the triboelectric effect
- Evaluate the signal of a electric charge difference generated by different raw materials during the winding process.
- YarnMaster PRISMA yarn clearers incorporated with the new generation of P4-sensors complements the unique approach of Loepfe’s unconventional yarn clearing concept of total quality control in the winding process
Four sensor technologies interact intelligently and ensure unprecedented fault visibility and data quality.

A WORLD OF CONNECTIVITY
A WORLD OF COMFORT
PRISMA GUI – EASY AND INTUITIVE OPERATION.
The heart of the YarnMaster PRISMA yarn clearing concept is the simple and intuitive new PRISMA operating system. Easy operating and navigation controls ensure a high user acceptance and productivity.
The menu guidance by an intelligent wizard enables a straightforward and intuitive operation of the comprehensive information provided by the innovative new YarnMaster PRISMA operating concept.
- With the intelligent settings assistant, you can continually optimize processes and make them more efficient.
A WORLD OF DIGITALISATION
MILLMASTER TOP 2.0 – CONNECTS AND INFORMS
Effective online quality management is one of the key success factors for winding and open-end spinning machines today.
Loepfe allows you to analyze yarn quality more easily than ever and to evaluate data individually.
- Our data management cockpit has never been easier to operate.
- Intuitive and consistently focused on benefits.
