Corolab XQ/XF –
the yarn clearing system with a future
Simple – Compact - Precise
Yarn faults are a topic that those in the textile business have lived
with for generations. Possible complaints about wovens and knits
arising from these can become a high cost factor for any company
- costs that are a thing of the past thanks to the Corolab XQ/XF
sensor system.
The Corolab XQ/XF sensor system comprises digital sensor technology
that is integrated into every spinning unit on the Autocoro rotor spinning
machine. Current clearing information is displayed on the operating
and display unit belonging to the system. Receiving the clearing
settings requested individually by the user and communicating these
to the individual sensors is one of the tasks of this unit.
To make the settings easy and compact for the user, Oerlikon
Schlafhorst has developed a matrix system for Corolab XQ/XF that
can be used universally for the individual yarn clearing sections. This
matrix principle is also used for classifying and displaying the yarn
faults. The clearing setting and clearing result are accessible to the
user at a glance. The clearing parameters can be saved easily in the
article memory and are thus always available for later applications.
Matrices of the Corolab XQ/XF:
• Short fault matrix for the areas thick places,
thin places and faults appearing in bulk
• Long fault matrix for the areas of sliver defects
and yarn count faults
• Foreign fibre matrix for the area of foreign fibres
Defining the clearing limits for the short fault and long fault matrices
is generally based on the criteria yarn fault length [mm] and yarn
diameter deviation [%], for the foreign fibre matrix on the criteria
foreign fibre length [mm] and brightness deviation [%]. The level of
clearing is determined precisely by activating individual matrix classes.
Short fault matrix
The short fault matrix is divided into the thick place and thin place
range. Cleared faults as well as faults remaining in the yarn are
recorded in the individual matrix classes. Short, consecutive thick
places appearing in bulk can be cleared precisely by additionally
activated matrix fields.
Long fault matrix
Innovations
The long fault matrix is divided into the areas sliver defects and yarn
count faults. Sliver defects, which cause yarn faults up to 10 m in
length with a positive or negative yarn diameter deviation, are detected
in the ranges sliver thick and sliver thin and cleared. Yarn count
faults, which cause yarn faults up to 10 m in length with a positive or
negative yarn diameter deviation, are detected in the ranges yarn
count thick and yarn count thin and cleared.
