FLANGED FEEDER BELT COMPOUNDS Beltservice offers a variety of flange compounds to match the cover compound of the desired base belt. For special applications, consult our Feeder Belt Department to create the exact construction needed by your customer. Matching the flange compound to the belt compound provides superior construction and uniform properties for the entire belt. The majority of Beltservice flange profiles are fabricated with rubber compounds, PVC, or urethane: • Rubber Flanges – Standard rubber flanges are 60 durometer and available in black SBR, black Nitrile, and white Nitrile. For high temperature applications, special flange compounds of white or black Butyl are stocked. A unique problem-solving flange is our 40 durometer rubber flange. This flexible flange will operate on smaller diameter pulleys and can be flexed upwards on conveyors requiring a change in elevation. • PVC Flanges – In some applications PVC is an economical alternative to rubber flanges. Flange heights range from 1” to 4” (25mm to 102mm). PVC flanges are hot welded to a PVC base belt and stocked in black or white. Ideal for wet, oily, or acidic conveying conditions. • Urethane Flanges – Available for super rugged applications. Urethane flanges are strong and abrasion resistant. Siping (also called slitting) of urethane flanges is recommended. All standard heights are available. • 1-1/2” (38mm) Rubber 90° one side • 2” (51mm) Rubber Standard • 2” (51mm) Rubber Special 90° one side RUBBER FLANGE PROFILES The following are Beltservice’s most common rubber flange fabrications that help increase conveyor capacity while decreasing material spillage. • 1/2” (13mm) Rubber • 3/4” (19mm) Rubber • 1” (25mm) Rubber FLANGE FABRICATION OPTIONS There are five options available to help a flanged feeder belt operate on smaller-diameter pulleys: • Solid – Styles available: Gumdrop, Tapered One Side, and Tapered Both Sides. Note that all styles are not available in all the standard heights. • Siped – Siping involves slitting the flange down to the surface of the base belt. This allows the outside edge of the flange to expand as the belt navi- gates the pulley, decreasing the stress on the flange. • Drilling and Siping – Similar to siping, except that a relief hole is drilled at the base belt’s surface. This prevents the siping from propogating further. • Notching – The most effective method of relieving stress on a flanged belt. A notch with a radius allows the flange to easily negotiate the curvature of the pulley or weigh span. When accuracy is the top priority, this style flange offers the precision necessary for weighing • Corrugated – Corrugated sidewalls can be used when the feeder’s pulleys are too small for flanges or greater height is required for higher capacity feeders. Sidewalls can be hot bonded with matching compounds. Y AND INNOVATION FROM THE LEADER IN Siped Flange Corrugated Drilled & Siped Flange Notched Flange
