STRC - Introduction
01
STRC
In-line and continuous measurement of your textile cloth.
Monitoring console
The monitoring console enables the display and recording of curves as well as access to all system functions.
Travelling bridge
The STRC bridge is available in widths up to 7 m of product in steps of 25 cm.
Description
02
Checking the quality of textile products at line output
The STRC (Serel Travelling Regularity Control) has been designed to continuously measure the transverse and longitudinal regularity of a textile (or other) product. It enables the checking of fine and light cloths as well as dense and thick products.
The X-ray generator is chosen for this particular application in order to ensure optimal levels of accuracy.
Points Clés
03
No radioactivity
The system uses an X-ray generator and not a radioactive source. Therefore, it is totally safe when it is switched off.
Compton scattering
By combining the measurements of absorption and Compton scattering, the STRC makes it possible to measure highly heterogeneous blends of fibers such as glass and PP fibers. Indeed, this method is sensitive to both light and heavy materials in a blend.

Options
Thickness measurement
Either in addition to or in place of the X-ray density measurement system, the STRC can be fitted with a system for ensuring the thickness of the cloth, which is based on laser technology. Similar to the measurement of density, the measurement of thickness is continuous across the entire width of the cloth and it is displayed in the form of curves on the monitoring PC.
Entry and/or output rollers
Height adjustable rollers for the travelling bridge are available as an option for integration into an existing production line. They can be matched accordingly in order to suit the most efficient progress of the textile.
Closed loop
The STRC enables the automatic regulation of the quantity of material that enters the card in order to attain the target weight at the end of the line. However, this option is only available if the automatic operation of the STRC is coupled to the regulation of density at the entry to the card (SLDC).
The STRC can also be connected to a PC of any kind via a Profinet or Profibus connection that permits the transfer of composite curves and curves which display information regarding the status of the STRC.
Remote maintenance
The presence of the PC or STRC enable Serel’s engineers to access equipment in record time and thereby minimize any production downtime.
