Honeycomb Conveyor Belt

Also known as Flat Wire belting

Honeycomb is an ideal choice for any application which requires both durability and an open belt design whilst maintaining a flat carrying surface. Its high strength-to-weight ratio also makes it an ideal choice for customers keen to improve their energy efficiency.

Honeycomb flat wire beltHoneycomb belting, also known throughout the industry as Flat Wire belting, is a straight-running belt with an extremely high strength-to-weight ratio. It is available in a wide variety of aperture configurations to suit applications as diverse as casting, baking, drainage and packaging.

Honeycomb is constructed from formed flat wire strips connected by cross rods running through the width of the mesh. The rods are finished with either welded button edges or hooked edges.

It is a strong, lightweight, positively driven belt.  A large open area makes this belt particularly suitable for processes such as washing, drying, cooling, cooking.

Sprocket Material

Available material types include:
  • 'Oilon' (Polyamide Cast Nylon 6 - lubricated) FDA approved.
  • PA6G (Polyamide Cast Nylon 6) FDA approved.
  • Stainless Steel
  • Mild Steel
  • Cast Iron

Drive, Idler and Belt support

The drive should pull the belt in the upper loaded segment.
For belt support guide rails made of plastic, steel or brass should be used. Material used for this, alignment and placement intervals depend heavily on the expected belt load, belt weight and the application it is used in.

For the lower run we also recommend to support the belt.

Honeycomb belt is being driven slipfree by using sprockets. These should be placed in intervals of no more than 150 mm across belt width.
For the idler shaft blanks may be used. As an option free rotating sprockets can be placed in the belt edge area in order to improve belt tracking.

Belt tensioning

Usually the use of an adjustable idler shaft is sufficient for belt tensioning. However, in long conveyors or applications with significant temperature variations a more sophisticated take-up system should be considered.

Installation Guidelines


Before installing a new belt, always check the conveyor structure;
  • Shafts to be at 90º to direction of travel and horizontal.
  • Rollers to be free to rotate.
  • Sprockets to be correctly positioned, and aligned.
  • Belt supporting surfaces are smooth and level.  Check that there are no parts of the structure that can catch up the belt.
  • If a take-up mechanism is fitted, ensure that it is functioning correctly.

Installation Procedure
  1. The belting should be pulled through the conveyor circuit until the two ends meet.
  2. Excess belting should be cut off at this point
  3. Temporarily, the two ends can be tied together; they may make assembly easier
  4. The belt is joined by inserting a connecting rod through the pickets at the ends of the belt.
  5. The connecting rod should then either have washers welded to the edges or be rotated until it hooks onto the next clinch, depending on type.

The belt has to be installed with the correct direction of travel. Splicing cross rods are supplied with the belt. Depending on the edge style they will either have one side having a welded button edge or a pre-clinched edge.
The apertures of both ends of the belt will then be aligned and, if necessary, can be fixed using cable ties. The splicing rod is then being pushed through the holes of the belt strands.
In the case of a welded edge the button head (nut) is being placed on the end of the rod and welded to it.

Note; Sometimes a belt can show signs of surging, hunting or jerking. What could be happening may be an effect sometimes referred to as “slip-stick” which can afflict some longer conveyors (with any type of belt). The belt can act something like a spring. The idle end of the belt can remain stationary until belt tension increases to the point that static friction is overcome; the belt can then surge ahead and the resulting drop in tension may then allow the belt to slow, or even stop. The cycle of surging can then become repetitive; if this problem persists then consult the designer or manufacturer of the conveyor.

Honeycomb Trouble shooting Guide

Belt Tracks to One Side

Possible Causes Solution
  • Drive/Idler shafts unaligned
  • Belt damaged on one side
  • Uneven loading of belt
  • Conveyor frame distorted or uneven
  • Ensure that all shafts are perpendicular to the direction of belt travel
  • Inspect belt for damage and replace if necessary
  • Adjust product distribution on belt
  • Inspect conveyor structure and repair any distorted/uneven members

Belt Grows in Pitch

Possible Causes Solution
  • Belt material unsuitable for operating temperature
  • Excessive tension in belt circuit
  • Consult technical sales to determine best material for application
  • Reduce belt loading or replace with stronger specification

Excessive Wear to Sprocket Teeth

Possible Causes Solution
  • Excessive tension
  • Belt mis-tracking (see above)
  • Sprockets set-up incorrectly
  • Insufficient sprockets
  • Deflection in drive shaft
  • Reduce belt loading or replace with stronger specification
  • Check for tracking issues and remedy if required
  • Consult Technical Sales for advice on drive shaft layout
