Screens for classifying, sizing, straining, sieving, are typically secured to a vibrating deck by clamping rails that apply tension across the screening surface.
The tension is applied through edge treatments on the woven wire cloth screen panel commonly referred to as "hooks" , "hook strips" or "hooking strips".
Proper screen tension is crucial for effective screening and longer screen life.Banded edges prevent flattening of hook edges and eliminate mesh pull-out on fine wire mesh or high tension screens.
Plain Hooked Edge
Without Reinforcing, Typically provided on screens of 5/16" and larger wire diameters. Edges are annealed before forming to eliminate cracking and breakage.
Inside Reinforced Formed Edge
This hook strip is utilized for screens 5/16" and larger wire diameters. Edges are annealed before forming to eliminate cracking and breakage.
Reinforced Shroud Banded Edge
Provided as standard on screens up to 1/4" wire diameter. Standard shrouding is 16 gauge with other thickness' available on request.
Double Folded Reinforced Shroud Banded Edge
This treatment eliminates screen pull-out on screens woven of smaller wire diameters. Standard shrouding is 20 gauge with other thickness' available on request.
Double Reinforced Shroud Banded Edge
This treatment also eliminates screen pull-out on finer wire sizes. It includes a internal metal insert for reinforcement. Standard shrouding is 20 gauge with other thickness available on request.
End Tension Reinforced Shroud Banded Edge
Specially reinforced to prevent pull-out under extreme screen tensioning. Also available in Double Reinforced Style.
When ordering screen edge preparations, give vertical height of hook (H) and angle of formed edge (A).
