Page 11: Yarn Clearing (General)
YARN CLEARING GENERAL Yarn Clearing (General) Definition of Yarn Faults The Open End spinning process supplies a relatively uniform yarn. However, differences in yarn diameter cannot be com- pletely avoided. Thus, it is first necessary to distinguish be- tween normal yarn irregularities and actual yarn faults. Yarn faults may be defined as yarn irregularities which can lead to difficulties in subsequent production stages or to faults in the end product. - Page 12 YARN CLEARING GENERAL Accumulations of Faults (Moiré) ƒ Periodic defects (moiré) Periodic Periodic defect where the period is related to the rotor diam- eter of the OE rotor. They can be caused by contaminated or used rotor ƒ Other periodic defects Other periodic They can be caused by defects or wear from components of defects...

Page 13: Yarn Fault Classification
YARN CLEARING GENERAL Yarn Fault Classification Figure 1 Yarn faults are defined in terms of a transverse dimension and a longitudinal dimension. The transverse dimension is ex- pressed as a deviation of normal diameter and the lon gi tu di- nal dimension in millimeters. -

YARN CLEARING GENERAL Yarn Clearing Base Curve Figure 4 The distinction between yarn faults which are to be cut out and those which are to be left in the yarn (unacceptable and acceptable yarn faults), which is made in the interest of Open End spinning efficiency, has already been pointed out. -
Page 15: Foreign Matter (F)
YARN CLEARING GENERAL Foreign Matter (F) The human eye is determining color differences by detecting differences in light absorption. The sensor for foreign matter incorporated in 3N1 is measuring these differences in light absorption to detect foreign matters in the yarn in a most ef- MASTERS IN TEXTILE QUALITY CONTROL fective way. -

When starting the test each rotor of the chosen rotor range will go into a forced lock one by one starting with the smallest rotor number. At the same time also the rotor position will go into red light if the interface cable between the SE and the machine section electronic is connected the right way.
- Page 38 Hardware Locks / Recommended Action LOEPFE 3N1 has a built-in diagnostic function. Technical problems are indicated by means of hardware locks. Hardware locks can be cancelled by using the unlock card, from the SCU or with button on sensing head. Since hardware failures of this kind can have a severe influence on yarn quality, they should be corrected and reset by qualified personnel only.
