E+L Systems on the FABRIC CALENDAR LINE

Komponenten von Erhardt+Leimer an der Reifenmaschine
  • Precise tension measurement
  • Output signal for closed loop tension control
  • High overload rating

The SRS63 steering roll system (option: ELGUIDER) corrects the web position to the machine centerline before it reaches an accumulator, calender or wind-up. Digital infrared sensors constantly monitor the edges of the web. The liner material is correctly wound using SR41 steering roll systems at the wind up station. 

The digital E+L system regulates the tire cord web to a defined width. Using a combination of electronic broadband edge sensing system guarantees smooth and clean production. The CordAliner BCS21/31 allows the entire width of the tire cord web to be stretched before entering the calender heating cans or wind-up.

The EPILiner BCS11 edge spreading system works directly on the edges of the web using two independent three-finger spreaders. The required width is achieved before the web reaches the calender nip.Optionally available with pre-positioning VE53.

  • Automatic splice detection
  • Automatic detection of thread thickness and spacing
  • Flexible controls (outer edges, centre cord, thread count or even thread distribution)
  • Recipe management incl. settings for web width and web guiding controller
  • Automatic recipe change on detected splice
  • Recipe changeover within the web width controller and web guiding controller at the time of splicing pass
  • Online viewing and logging of defects Interface for automated transfer of the next roll data (recipe)
  • Parallel control via OP panel possible 

In combination with a CCD camera system with 12 cameras, the EPI Cord Distribution Measurement sets new standards in the measurement and control of cord distribution. With an intelligent combination of control and inspection, the system automates the production process and guarantees higher quality and efficiency.

  • Contactless laser & Eddy Current sensor
  • High precission thickness measurement
  • Thickness profile with traversing sensor
  • Output signal for thickness control
Beispielzeichnung Traversing Thickness Measurement

Detection of missing rubber on top or bottom. An array of CCD cameras OL 91 is mounted on the front and back side of the calendered steel cord. High intensity LED lights provide the illumination. The cameras evaluate the surfaces continuously and save defect data in a database for quality control.

  • Defect signal communicated to PLC
  • Complete image processing within cameras
  • Optional with tension control
  • Integrated loadcell
  • Single sided sensor for easy liner handling
  • Compact guider
  • Integrated to existing network

Highly compact CCD line scan camera systems OL 82 measure (without touching the web) the rubberized steel cord. The width can be fed back to the pre-calender spreading systems.
