Positive Drive Chain Edge (PDCE)

Positive Drive Conveyor Belts for Exacting Applications.

When your application requires positive drive, indexing or synchronization, a chain edge design is the practical choice. Positive drive conveyor belt assemblies employing a chain edge are also widely used due to their uniformity in pitch, high tensile strength with relatively light belt/chain weight, and good durability under severe loads.

CUSTOM DESIGNED FOR YOUR APPLICATION
PDCE are truly custom conveyor belts, whereby either standard or special chains are added to a custom designed support system for your product and process. PDCE conveyor belts can be produced using many different materials including various grades of malleable iron, high strength cast alloys, heat treatable malleable iron, stainless and carbon steel.

ASHWORTH BELTING PROFESSIONALS ARE READY TO ASSIST YOU
Many different wire mesh configurations are available, including balance weave, compound balance weave and conventional weave. Plastic modules are also available to serve as the product support surface. However, the appropriate wire mesh or module is both application and belt support member specific. Ashworth belting professionals stand ready to assist you in selecting the proper combination of chain, cross supports and mesh overlay, plus any required guard edge plates, lifts or lane dividers to meet your specific requirements.

Positive Drive Chain Edge

Available Options:
  • Guard Edges

    Guard edges are located on the inside of the chain. Height above the belt surface and material is customer specified. Guard edges are usually used with round cross supports (rods, turned down rods, or pipe/ rod) which are inserted through holes in the guard edge.

    Guard edges are generally plates that may be offset, of interlocking design, or flat plates that are assembled in either a shingled or staggered arrangement. Plates can be square or rectangular and either flared or notched as required (Figure 18). Plates with double tabs may be used. The bottom tabs may be inserted through the mesh or the tabs may straddle the mesh and are welded or brazed to it. Whenever guard edges are specified, the inside guard edge (IGE) dimension should be specified by the customer.

     

  • Flights (Lifts or Cleats)

    Generally, flights are attached to the belt by welding or brazing them to the mesh and/or the guard edges (if applicable). The style, material, height, and spacing above the belt surface is customer specified. The length of the flight is usually the same as the mesh width but can be narrower if specified.

    Usually, flights are produced from formed angle stock, although commercially available flat bar, keystock, cut sheet metal, or other customer specified shapes may be used. Angle types usually have slots or holes punched in the bottom to facilitate plug-welding to the mesh. It should be noted that flights are not meant to carry product up inclines but are just to prevent product slippage.

  • Wipers

    Wiper attachments, typically fabricated from wire mesh, hang from the bottom surface of the belt to wipe debris from drip pans, trays, bins, etc. These attachments are typically attached to belt mesh with a straight or crimped connector rod. Mesh designation (if applicable), material, length below belt surface, width of wiper, and spacing are customer specified.
