Improved roller head unit
To meet the stringent requirements of the market, Kraiburg has started offering calendered plates produced on a new roller unit.

The production line sets new standards as regards quality due to the use of a cold-feed pin-type extruder that ensures gentle and uniform heating and mixing of the material, which is then processed to calendered sheets.

Processors including manufacturers of rubber rollers benefit from a number of improved properties like better surface finish with smoother plates that are nearly 100% free of blisters. The new calendered sheets are available in thicknesses of 0.3 to 10 mm and a maximum width of 1,500 mm. The combination of automated roller gap adjustment and integrated online thickness measurement also ensures dimensional accuracy during production.

The production line consists of the QSM 150 pin-type extruder with automated screenchange system; two-roller calender (600 x 2,000 mm) with hydraulic roller adjustment and continuously adjustable drive; laser monitoring of the dimensional accuracy and automated roller gap adjustment; four cooling drums; two semi-automatic centre winders with intermediate rotor unwinding station and process data recording with a roll weight of 30 to 500 kg.
