For a mechanical splice to function in a transfer point and allow effective sealing and cleaning, both the top and bottom splice sections must be recessed sufficiently into the belt to keep the belt thickness constant and the splice surface smooth, to avoid damage to components and the splice.
Cutting down the covers of the belt, typically called skiving, mounts the fasteners closer to the fabric of the belt carcass for a firmer grip. Skiving requires the top and bottom covers be cut down to the belt carcass. As the carcass provides the strength of the belt, and the top and bottom covers provide very little strength, this will not reduce the integrity of the belt or splice.
Mechanical splices that are not properly skived can cause sealing problems at the load zone and impede belt cleaning at the head pulley.
Great care is required when skiving the belt, as any damage to the carcass of the belt can weaken the splice and therefore reduce the strength of the belt. When the splice is properly recessed, the metal components of the mechanical hinge will move without incident past potential obstructions such as impact bars, rubber-edge skirting, and belt-cleaner blades. Skiving is recommended to ensure the integrity of the belt, splice and other conveyor components. Skiving the belt reduces noise in the conveying operation, as clips are now recessed and do not “click clack” against the idlers as the belt moves through the system.
Skiving equipment can be purchased from most splice suppliers.
