Web Stabilizers and Pocket Ventilation

Maximum draw reduction is achieved with AirCurtain for center roll sheet release.

Benefits:

• Excellent runnability
• No mechanical contact between the stabilizer and the press felt / drying fabric
• Easy and safe tail threading
• Draw reduction between the press and dryer section
• Reduced number of breaks and defects
• Better paper quality
• Increased speed potential
• More tolerance to process fluctuations
• Maintenance free construction due to no wearing parts

The negative pressure level required on the dryer fabric side of the opening nip is highly dependent on the production speed. The negative pressure must exceed the pressure on the paper run side, thus making the paper web to follow the fabric instead of the smooth cylinder surface.

High release nozzle technology of the EasyOne enables the required under pressure levels without edge or cross direction nozzles. Thus, there is no further need to blow hot supply air to the stabilizer saving a great deal of energy. Moreover, the construction is maintenance free enabling 100% efficiency without any service requirements to the web stabilizers. In addition to the reduced running costs, the development means lower investment costs for any traditional air system equipment or lay-out demands.

Benefits:

• Draw reduction typically between 15 - 40 %
• Possibility to reduce furnish quality
• Possibility to increase steam pressure without losing runnability
• Reduced porosity due to lower tension between the press and dryer section
• Increased sheet elongation
• Reduction in web breaks typically 20 - 60% compared to standard “low vacuum” stabilizers
• Easy ropeless tail threading and less widening breaks
• Significant cost savings in consumable costs due to no need for wear parts
