YarnMaster® Zenit

YarnMaster Zenit, the online quality control system by Loepfe, has a completely new design, but also incorporates the extensive experience gained from the successful YarnMaster Spectra. It is intended for customers with the highest demands on yarn clearing and yarn quality who want to be assured of safety and reliability, even under the most problematic ambient conditions. Moreover, the system offers a platform for the addition of future innovations.

The main features are given as under:

• Sensing head user interface: A 7-segment display is built into the sensing head providing information of occurrences at the spindle.
• Central unit user interface: A color touch screen with multi-lingual capabilities, clearly organized graphical display, offer ease of use to operators.
• LabPack functions: The online laboratory for the detection of off-standard bobbins with respect to hairiness, neppiness and irregularity (CV).
• Improved detection of foreign matter: now also in colored yarns.
• For all staple fiber yarns, independent of the spinning process and fiber material used.
• For all splicer types.
• For large yarn count ranges, such as  TK YM Zenit for Ne 2.4-320 and TK YM Zenit F(P)           Ne 4.1-320.
• Channel Clearing offers Opto-electronic precision and Yarn clearing with clearer channels. (see diagram)
