Secure missing and off-center core detection: PRISMA is the solution, combining its unique simultaneous dual measurement with its core yarn features. Thanks to the simultaneous optical and mass sensor measurement, 100% of the yarn is analyzed in regard of mass and hairiness variations. This technique accurately detects the occurrences of missing and off-center cores.

Effortless operation with core yarn setting proposal: In addition to the unique measurement methodology, PRISMA also provides setting support. Thus, PRISMA creates a suitable core yarn setting proposal based on the settings of the yarn parameters and core properties. Providing the operator with maximum support for successful core yarn production.

Elimination of fluffy places: Clever yarn clearing is profitable, efficient, and easy. It requires precise removal of disturbing NSLT faults, such as fluffy places, to meet quality goals. PRISMA offers efficient NSLT clearing, ensuring accurate fault detection, classification, and cut execution.

Precise off-standard alarms & yarn count control: The PRISMA Software offers reliable and accurate detection of off standard bobbins through two Textile Alarms: OffStandard bobbin and Bobbin startup alarm. The Textile Alarm OffStandard bobbin detects yarn that falls below a predefined quality level during the winding process and promptly alerts the winding machine for a quick resolution. The Bobbin startup alarm is ideal for spinning mills aiming to enhance profitability by detecting bobbins with incorrect count and optionally color within the first 11 to 20m of winding, providing the fastest detection of faulty bobbins available. This alarm reduces waste, improves production efficiency, and allows for better monitoring of material processes.

Best contamination control: PRISMA’s all-color foreign matter detection provides spinning mills with new possibilities in terms of quality, profitability and raw material utilization. The unique RGB technology achieves outstanding measuring accuracy. Previously undetectable disturbing contaminations can now be removed while the non-disturbing matter are correctly classified. Offering the most efficient foreign matter detection, results in flawless yarn quality, increased profitability and improved raw material utilization.

Clever organic filtering: PRISMA increases efficiency with a holistic and unique approach. RGB technology enables color-oriented selection of organic material in cotton yarn, which does not necessarily have to be removed, as it does not cause disturbances in downstream process steps and is eliminated by other means. This contributes to a significant reduction in cuts while maintaining the yarn quality.

P-Sensor: Loepfe has been at the forefront of mastering the triboelectric effect for years, and PRISMA is the latest testament to this expertise. PRISMA DMFP is equipped with the latest P sensors from the 4th generation and a dedicated P-Matrix, ensuring accurate settings and reliable results. PRISMA is the solution to ensure reliable detection of white and transparent polypropylene in yarn production.
