One of the significant advantages of lightweight belting is the splicing versatility and excellent properties of the splices. In particular, the thermoplastic category of belts utilizes that property to allow heat-welded splices that exhibit a high percentage of the original belt flexibility and strength. Typical splices possible in the lightweight category are:

  1. Mechanical (metal): For all lightweight belt types. Offers quick installation and low cost with some potential disadvantages such as reduced flexibility, noise, pollution, and product damage.
  2. Finger and Double Finger: Primarily used on thermoplastic belts. These heat-welded splices offer excellent flexibility and high strength particularly with the double finger. The double finger is also more reliable in polluted environments, v-guided belts, and in side loading circumstances.
  3. Step: This splice retains the highest percentage of the belt strength and is used in heavier applications. It is also more reliable for trough applications. Hot or cold (glued) splices are used on the thermoplastic belt style while a glued cold bond is most commonly used on the rubber belts.
  4. Skive: This is a common splice for nonwoven belts and is an alternate splice for thermoplastic and rubber belting. This splice can be done as a hot- or cold-glued splice.
  5. Plastic spiral: Nonmetallic plastic lacing is mostly used with thermoplastic belting. A main use is in the food industry for metal detectors or wherever you want to avoid metal. It also is quieter and more reliable than metal lacing in many high-speed applications and is, therefore, finding wider use in the logistics industry.
  6. Quick butt weld: A convenient and quick butt weld is possible with the solid plastic belts using specialized splice equipment.
