Conveyor belt joints and joining clips

HBS Wild has developed and adopted a wide range of conveyor belt joining methods – all designed and implemented to ensure minimal difficulty for consumers and easy replacement if parts break, or for general wear in some cases.

General clip forms are now categorised as ‘F’ type clips – where the links of the joiners form an ‘F’ shape, seamlessly interlocking when fixed the correct way at opposite ends of the conveyor. The interlocking ‘F’ type clips are secured using a turned rod. The joining rod, which is lathe-turned to fit into the interlocking clip, is grabbed by the ‘F’ type fingers. This prevents lateral movement of the rod, and lessens damage to the harvesters' fabricated body, drives and rollers.

There are three other types of steel clips used as conveyor belt joints. These are referred to as short pin joiners, ferule clips or a ‘male’, ‘female’ type clip.

Typically, short pin joiners are used in such cases as pintle webs, where the pitch of the conveyor does not need to be detailed in the pitch of the joiner – but parts of the joiner need to be regularly replaced due to high speed and water-based use. Short pin joiners are made up of a number of parts; the clip itself, male and female ferules, 10mm joining pins and fixing screws and nuts.

Ferule clips are based on similar principles; this belt joint method allows conveyors to circulate with disregard to the pitch of the web itself. Generally, this type of clip is used when sprocket drives are not used. Ferule clips also use a steel sleeve or ‘ferule’ to reduce wear on the clip, which means a straight rod is used for joining, as opposed to a turned rod. These rods are locked in place using a locking collar, which is fastened internally to the clip using a chamfered grub screw.

Alternatively, endless joining, overlapping or splicing can be used. This method is clip-free and essentially hides the join – limiting any chance of the join catching and reducing the number of parts needing replacing. This method is the strategic cutting or splicing of the belt at each end in a stepped form. This can be a one-step, two-step or three-step cut depending on the size of the join. This stepping is designed so the belt thickness remains the same when the belts are ‘lapped’, therefore seemingly endless. The lap joint is fastened using tapped or threaded bars of the same sort throughout the conveyor.

If you're looking for conveyor rollers, HBS Wild provides precision-made parts for a variety of conveyor types.

CLIP JOINER, TYPE A

  • Highly used and recommended joining solution produced by HBS Wild.
  • Uses an ‘F’ formation to join conveyors at each end, meaning clips can be used at either end.
  • Available for used on 60, 50 and 40mm wide belting.
  • Respectively, available in 32, 25 and 20mm hole centres.
  • 3mm spring steel to avoid dramatic deformation and weak point reinforcement.
  • Utilizes a lathe turned joining rod (10, 11 0r 12mm spring steel rod)to joining interlocking ‘F’ style fingers and prevent lateral movement of the rod.
  • ¼” threaded bolts and nuts for fastening.
  • Can be used for any number of traction belts.
  • Easily replaceable
  • Available in pitches: 25, 28, 30, 32, 35, 38, 40, 42, 45, 50
  • Highly customisable.

CLIP JOINER, TYPE B (male and female)

  • Old style conveyor joining systems.
  • Requires designated ends for each clip as it uses a ‘Male’, ‘Female’ locking formation.
  • Available for used on 60, 50 and 40mm wide belting.
  • Respectively, available in 32, 25 and 20mm hole centres.
  • 3mm spring steel to avoid dramatic deformation and weak point reinforcement.
  • Utilizes a lathe turned joining rod (10, 11 0r 12mm spring steel rod) to join interlocking ‘Male, ‘Female’ style fingers and prevent lateral movement of the rod.
  • Can be used for any number of traction belts.
  • ¼” threaded bolts and nuts for fastening.
  • Easily replaceable
  • Available in pitches: 25, 28, 30, 32, 35, 38, 40, 42, 45, 50
  • Highly customisable.
  • Works identically to clip joiner, type A.

SHORT PIN JOINER, TYPE C

  • Very common conveyor joining method for Pintle webs and harsh metal surfaces must be hidden to avoid damaging crop.
  • ‘Male’, ‘Female’ type joining systems used, meaning clips are used a specified ends.
  • Used only with friction drives as clip pitch may differ from belt pitch.
  • Ferules inserted in male and female arms to prevent wear on clip when pintles travel at high speeds.
  • Ferules are easily replaceable and avoid the need for new clips.
  • 5mm spring steel.
  • ¼” threaded bolts and nuts for fastening.
  • 38mm pitch from bar centre to bar centre.
  • Standard available for 60mm at 32mm hole centres but can be customized to suit smaller.
  • Used a 10mm flanged joining, fastened by washer and split pin.
  • Systems ensure pintle covers clip and avoids damage to crop.
