The manufacture of an endless abrasive belt from a roll of abrasive paper or abrasive cloth requires that both ends of the previously cut-to-length section of the roll be joint by Abrasive belts splicing tape permanently. The so-called belt joint usually runs at a 55˚, 57˚, 75˚ angle to the running direction of the belt in order to prevent an abrupt transition at the junction.
The abrasive backing (paper, cloth, plastic) used and the application (machine, contact element, work piece) determine the type of the Abrasive belts splicing tapes.
The butt splicing joint which is formed by two ends that abut each other and are joined by means of a narrow strip of Abrasive belts splicing tape on the reverse side of the belt.
