There are a number of popular conveyor layouts that are appropriate for using Flat-Flex belts. We have divided these into General Best Practices and Application-Specific Practices. The most frequently used are shown here below and include: Simple Conveyor Layout; “S” Drive Layout; Alternate “S” Drive Layout; the Infeed, Twin Layouts, Center Drive Layout and the Bi-Directional Layout.
Flat-Flex belts are designed to be positively-driven by sprockets to eliminate the tracking and slipping problems that commonly occur with other types of belts. Whenever possible, the drive should be placed so that the loaded portion of the belt is pulled (not pushed). For best results, the drive shaft should be located as close to the discharge end of the conveyor as practical. The drive sprockets positioned on the shaft assembly should engage the belt along 120° to 180° of the sprocket circumference. (This is sometimes referred to as “sprocket wrap.”)
Flat-Flex typically uses pairs of drive sprockets located in the odd-numbered spaces, with blanks supporting the outside edges of the belt. This arrangement facilitates sprocket alignment and allows the use of splicing clips for installation and belt repair.
Several of the typical conveyor layouts include one or more reverse bends. A reverse bend occurs when the belt flexes in the opposite direction from a transfer. Reverse bends are typically used to increase sprocket wrap or for take-ups.
The conveyor frame should be rigid enough to support the hardware which will drive and support the belt. Suggested materials include: stainless steel (for food processing applications), aluminum, painted, or galvanized steel.
The design of Flat-Flex wire belts provides one of the tightest possible transfers… with some meshes bending around end-rolls the diameter of a pencil. Various types of end-rolls and nosebars are used to facilitate the transfer of product between conveyors.
