Application Based Wedge Bar Designs
Parason has developed different wedge wire profiles considering open area requirement, slot size, strength, and fiber length for each application
3 Wedge Wire
1 Unit Length
Compact wedge configuration for fine screening with high open area and strength balance.
4 Wedge Wire
1 Unit Length
Standard wedge configuration offering optimal balance of throughput, slot accuracy, and structural rigidity.
5 Wedge Wire
1 Unit Length
Extended wedge configuration for maximum open area in high-capacity screening applications.
Design Considerations
Parason Low Pulse Screen Technology
Key activities that set Parason slotted baskets apart in screening performance
Cleaning Efficiency
Wedge wire baskets deliver higher open area compared to conventional baskets at the same slot size, with computer-controlled manufacturing for precise profile accuracy.
Rigid Construction
The special profile ensures a smooth and burr-free basket surface, providing consistent slot geometry across the entire screening area.
Uniform Flow
Flow across the profiled edge creates controlled turbulence, improving throughput capacity and cleaning efficiency throughout the basket.
Natural Flow Technology
Engineered flow dynamics for superior screening performance
Flow Advantages
Flow Balancing
More Flow, More Area
Flow Cleaning
Low Power
Applications
Developed for Parason screens and all existing non-Parason screens with associated rotor combinations from other manufacturers
Stock Preparation
Primary and secondary screening stages in stock prep lines
Broke System
Efficient screening of broke pulp for reuse in paper production
Approach Flow
Final screening before the headbox for clean sheet formation
Pulp Mill
Screening applications in virgin and recycled fiber processing

Manufacturing Excellence
Continuous improvement in our manufacturing methods delivers the highest precision in different slotted designs and roundness of the screen baskets. Each screen undergoes a hard-chrome plating process to improve wear resistance for extended service life.
Hard Chrome Plating
100 to 400 microns plating thickness for superior wear resistance
Electro Polishing
Smooth surface finish for reduced fiber adhesion and plugging
Stress Relieving
Counters welding-induced stresses for dimensional stability
