Martin Engineering updates industry-standard sealing system

New MARTIN® Double APRON SEAL™ Skirting

combines effective dual seal with double wear life

(Neponset, IL)—An improved version of Martin Engineering’s industry-leading APRON SEAL™ Skirtboard Sealing system now provides double the wear life.

New MARTIN® Double APRON SEAL™ Skirting provides two wear surfaces on a single elastomer sealing strip installed along the bottom of the skirtboard in a belt conveyor loading zone. When bottom side of the strip against the belt is worn, the sealing strip is inverted, providing a second service life.

Skirtboard sealing systems are installed on the sides of belt conveyor loading zones to contain material, eliminate spillage, and reduce cleanup expenses. MARTIN® APRON SEAL™ Skirting was the first dual-sealing system, as it incorporates a primary seal clamped to the steel skirtboard to keep lumps on the belt and a secondary or “outrigger” strip to capture any fines or dust that passes beneath the primary seal. The secondary seal lies gently on the belt and self-adjusts to maintain consistent strip-to-belt pressure despite high-speed material movement and fluctuations in the belt’s line of travel.

New Double APRON SEAL™ Skirting is available in lengths up to 300 feet (91 meters) to provide a continuous seal without seams that leak fugitive material. MARTIN® Double APRON SEAL™ Strips can be installed--using the existing clamps-as a replacement for previous APRON SEAL™ Skirting Systems or many other skirtboard sealing systems.

New Double APRON SEAL™ is one of the first products to be introduced as part of Martin Engineering’s New Architecture for Modern Conveying.
