Screen Sections in all Executions

Haver & Boecker offers a great variety of solutions for all types of screening machines in respect of weave and material, as well as of hook strips and tensioning techniques.

Strong hooks

Hook strips for Haver & Boecker wire screen sections are available in many different versions, and each of these for end and side tensioning. From standard hook strip to protection with PUR-strips, we manufacture industrial wire screens that suit your applications.

For special needs

Especially with hooked fine wire cloth screen sections, it is sometimes difficult to attain consistent tension of the screen section over the entire width or length. When tensioning is critical, we have two proven solutions: HAVER MONO and MULTISTRETCH screen sections allow for optimum tensioning. They cannot be overstretched.

Optional equipment

  • PUR-strips for extra wear protection
  • Stapled rubber seal / silicon seal
  • Glued silicon seal
  • Transfer plate
  • Flat tension profile
  • Tension screws
  • S-shaped hook strips
  • Wire cloth folded by 180°
  • Edge notching
  • Wire cloth cleaned by ultrasonic process

Secure fitting

Screen sections with hook strips can be tensioned along the sides or the end in reference to the flow direction.

Side tensioning has the advantage that screens are very easy to replace and re-tension: The tension screws at the side walls of the screening machine can be re-adjusted easily. In case of defect in a one- or multi-deck screening machine, just the damaged screen section must be replaced.

With screen sections for end tensioning machines, the area between the outside walls can be used over its full width. For improved sealing, additional rubber or silicon seals can be attached to the longitudinal sides.

Mono- and Multistretch

Especially with hooked fine wire cloth screen sections, it is sometimes difficult to attain consistent tension of the screen section over the entire width or length. When tensioning is critical, we have two proven solutions: HAVER MONO and MULTISTRETCH screen sections allow for optimum tensioning. They cannot be overstretched.

For multi-layer screen sections, HAVER MULTISTRECH provides for optimum tensioning of screen and support layer and for the proper adaptation of the length of the fine wire cloth. HAVER MONO and MULTISTRETCH screen sections are also suitable for use in food industry and with temperatures of up to 90°C..

Hook Stripe for the Food Industry

For use in the food industry with ambient temperatures of up to 120°C, Haver & Boecker offers a special food hook strip where the screen mesh is fixed to the hook strips and fully sealed with adhesives approved for use in foodcontact. Thus, complete cleaning of the wire screen sections is always possible, the formation of fungus and bacteria is prevented. All special hook strips are available for side- and end-tensioned screening machines.
