Details About Paper Machine

  • Back layer headbox

Hydraulic step – diffuser headbox with PE- tank. The Headbox is of proven hydraulic step fiffuser design to creat a high degree of microturbulences in the stock suspension to improve the formation. This very homogeneous stock suspension, as well as the possibility to adjust the jet geometry, is the basis for excellent sheet formation. The slice opening and jet speed ( pressure in the nozzle) can both be adjusted, accoring to the flow volume and basis weight.

  • Press Section

The first and second consists each of an X-ROLL as top roll with the SHOE-PRESS MATING ROLL( HV ROLL BCD) in the bottom position, double felted. Optimal felt conditioning is considered as well as measures towards keeping the press section “clean’, like splash walls, pans and enhousings. Easy roll and felt changed determaine the main framing struction on cantilever design.
