Screening with Tension: Pre-Trensioned Frames and Re-Screening Service

Before commissioning a screening machine, the operators must properly tension all screen sections with hook strips. In particular fine wire cloth sections may be accidentally damaged during the installation. For this reason, pre-tensioned screen sections are used for many types of screening machines. To produce these screen sections, the pre-tensioned wire cloth is carefully and evenly glued to the screen frame in a device developed by Haver & Boecker. In this way, optimum quality is guaranteed right from delivery, which is a precondition for high performance and a long service life. You only need to install the frame, then you can start screening right away. Haver & Boecker screen frames are manufactured in SCREENING WITH TENSION: PRE-TENSIONED FRAMES AND RE-SCREENING SERVICE. compliance with all applicable standards, monitored by our quality management system certified according to DIN EN ISO 9001-2008.
