Supply material such as wire or backsplice foil is often wound around rolls. If the roll is changed too early or too late, material loss and machine downtimes are the result. The KTS and KTX contrast sensors from SICK reliably detect the difference between supply material and roll, so necessary roll changes are automatically signaled at the right time.
