Lacing – Belt Fabrications

The most common way of installing belting on conveyors is by Lacing. A laced splice is simple to attach to a belt with the proper equipment and easy to install on a conveyor. In order to achieve proper results the belting must be absolutely square and the proper size lacing must be installed. Following procedures incorrectly could result in the belt not tracking and/or lace failure. Use our Lacing Chart and the descriptions below to determine appropriate lacing. The FLEXCO Product Handbook outlines specific lacing products and tools.

Clipper

Individual clips are installed via a special machine with minimal damage to the belt and joined via a pin. It provides a smooth joint that is excellent for trough conveyors and large pulleys.

Unibar

Individual clips are welded together via common bar, installed with a special machine and joined via a pin. The common bar design prevents hooks from breaking away. Not recommended for troughing conveyors.

Staple

Strips of steel with teeth are hammered into the belting and joined via a pin. A popular style for its ease of installation. Not recommended for troughing conveyors or large pulleys.

Plastic Rivet

large plastic plates are installed with a machine and then joined via a non-metallic pin. This lacing is designed for areas where metal cannot be used such as metal detectors.

Spiral Lace

Polyester webbing is vulcanized or sewn into belt ends and then joined via a non-metallic pin. Used in X-ray machines or metal detectors.

Bolt Solid Plate

Steel plates are bolted together to form a belt splice. Inexpensive tools are used in the installation. Used in heavy duty applications.

Rivet Solid

Solid plates are riveted to the belt while it is on the conveyor. A special tool is used to install this lacing. Used in extra heavy duty applications.
