PrimeRun web stabilization system

ANDRITZ PrimeRun web stabilizers enable a trouble-free paper run at reduced draw, even at high machine speeds. There are different modules and configurations to meet individual requirements.

The PrimeRun web stabilization system is ideally suited for fast single-tier and double-tier paper and board machines. It can easily be retrofitted to existing machines as part of a rebuild project.

Modules are the key

The PrimeRun web stabilization system consists of three modules that can be combined according to customer requirements:

Basic module 1 suction box PrimeRun D
Intermediate module 1 suction box and 1 roll PrimeRun D
PrimeVac
World-class module 2 suction boxes and 1 roll PrimeRun D
PrimeVac
PrimeRun HV

The PrimeVac roll is a core component of the new ANDRITZ web stabilization system and can be combined with the PrimeRun M and T. During the threading process, the PrimeVac roll fixes the web on the fabric with a pressure vacuum. This results in stable threading of the web through a single-tier drying section.

Ropeless tail threading is possible with the ANDRITZ PrimeFeeder for single-tier and double-tier machine configurations.
