Belt Technologies has developed an innovative concept in flat belt tracking called the ISP (independently steerable pulley), which can be used in the following system designs:
• Two pulley conveyor systems in which the ISP is the idler or driven pulley
• Systems with multiple idler pulleys on a common shaft
• Systems with serpentine or other complex belt paths
Steering flat belts with an ISP is based on the concept of changing tension relationships across the width of the belt by adjusting the angle of the pulley relative to the belt.
Rather than moving the pulley shaft left/right or up/down by pillow block adjustment, the ISP fits a variable steering collar and sealed bearing assembly to the body of the pulley.
