Control slack with photoelectric sensors

To make the supply of material layers continuous, there is usually some slack between the conveyor belts of the tire building machine. This compensates for the time offset between continuous feed and stepped processing stages. Photoelectric distance sensors continuously monitor this slack. They ensure that the slack isn’t less than a predetermined minimum or long enough to touch the floor, which would create a delay in the tire building process. The tire’s black material layers are highly light-absorbing, but this does not present a challenge for our optical sensors. They are also simple and intuitive to operate with their display and setting buttons.
