An open-ended, cylindrically configured cleaning cloth sleeve having elasticized openings at both ends for the purpose of securing the device, as positioned, on the hand, wrist or forearm of a user. Certain applications of the present invention are its use in various embodiments of a system for inspection of a printed circuit board substrate. An emission value of a second pollutant component is monitored in order to determine whether the emission value of the second pollutant component remains below a maximum value for the second pollutant component and whether an increase in the emission value to the maximum value for the second pollutant component is permitted. The upper guide portion restrains upward movement of the conductor material during the shaping operation.
