Abstract
A vacuum device is provided for use with a textile processing machine having a rotating roller with cleaning locations. The device has a vacuum generator, a main vacuum line operatively associated with the vacuum generator, a plurality of individual vacuum lines, and a vacuum control valve. Each of the individual vacuum lines has at least one cleaning opening. Each of the cleaning openings is for positioning at one of the cleaning locations. The vacuum generator creates a first vacuum at the upstream side of the vacuum control valve when the vacuum control valve is in one operating position, and a second vacuum at the upstream side of the vacuum control valve when the vacuum control valve is in a secondary operating position. The second vacuum is stronger than the first vacuum.
