In general, the latches are used to connect conveyor belts on which adhesives and melting techniques cannot technically be applied. A latch allows us to insert the belt on the machine as an open circuit, mount the belt without opening the chassis or the rollers, and close-circuit the machine after locking the latches in each other through a special pin. In terms of mold and appearance, the belt conveyor latches are classified into single-bolt and double-bolt, needle and hook.
