COMPARISON OF 1524 AND 1250 DIAMETER PRESSURE FORMER

The 1524mm diameter cylinder mould has a larger circumference, resulting in a lower RPM compared to the 1250mm diameter at the same speed as the paper or board machine. The advantages of 1524 diameter are as follows:

• Due to the cylinder mould, the forming zone also gets longer, which allows increased drainage, resulting in more machine speed.


• Better formation even at higher machine speeds due to reduced mould RPM and stock pressure.


• Better formation and brightness are achieved with less pick-up, thus saving material in the top layer, protective layer, and Bottom layer. Minimizing production costs.


• Longer wire and couch roll life due to reduced mould RPM.


• Higher Machine speed, hence increased productivity.


• It can be installed as a single unit or coupled with multiple units in a sequence of 1250mm-diameter formers.
