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.

A vacuum device for use with a textile processing machine having a rotating roller with cleaning locations, the device comprising:
- a vacuum generator;
- a main vacuum line operatively associated with the vacuum generator;
- a plurality of individual vacuum lines, each of the individual vacuum lines being operatively associated with the main vacuum line and having at least one cleaning opening;
- and
- a vacuum control valve operatively positioned between the main vacuum line and the plurality of individual vacuum lines and having an upstream side and a downstream side, the upstream side being opposite the vacuum generator,
- wherein 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,
- the vacuum generator creates a second vacuum at the upstream side of the vacuum control valve when the vacuum control valve is in a second operating position, and
- the second vacuum is stronger than the first vacuum.
The device of 3, wherein the second vacuum is sufficient to pull the waste material through the vacuum control valve.
A textile processing machine, comprising:
- a rotating roller with cleaning locations;
- and
- a vacuum device including
- a vacuum generator;
- a main vacuum line operatively associated with the vacuum generator;
- a plurality of individual vacuum lines, each of the individual vacuum lines being operatively associated with the main vacuum line and having at least one cleaning opening;
- and
- a vacuum control valve operatively positioned between the main vacuum line and the plurality of individual vacuum lines and having an upstream side and a downstream side, the upstream side being opposite the vacuum generator,
- wherein each of the cleaning openings is positioned 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,
- the vacuum generator creates a second vacuum at the upstream side of the vacuum control valve when the vacuum control valve is in a second operating position, and
- the second vacuum is stronger than the first vacuum.
