Tension Levelling Plant

Tension Levelling Plant

Strip processing guidelines have been developed for the high demands of the end products.

This tension levelling plant is designed as the final production stage in the manufacture of screen mask foil.

The strip is a substantial component of colour picture tube systems, which must be manufactured with metallurgical purity, a systematically defect-free surface, faultless flatness and very small thickness tolerance.

The line performs trimming, matting, cleaning and tension levelling.

Special Features:

  • Endless operation through strip joining the strip ends with a welding machine
  • Trimming facility for strip edges
  • Quarto - matting facility with strip cleaning
  • Flatness optimisation through roll-stretching facility
  • Roll-stretcher with automatic strip feed
