Abstract
The present invention relates to a process and device for the connection of a negative pressure channel provided with openings installed on a textile machine with a plurality of work stations. A service unit traveling alongside the textile machine is provided with a negative pressure line. The negative pressure channel has openings which are closed off by swiveling flaps. When the service unit is brought to a stop at one of the work stations, the flap associated with the work station is swivelled by means of an apparatus installed in the service unit and the negative pressure line is connected to the opening of the negative pressure channel. Before the service unit leaves the work station, the connection between the negative pressure channel and the negative pressure line is broken and the flap is necessarily swivelled by the apparatus so as to be in front of the opening in order to close the opening. The service unit has an apparatus capable of being moved in the direction of the closing surface of the flap in order to necessarily swivel said flap. The apparatus necessarily opens the flap as it moves in the direction of the closing surface and the flap is necessarily closed off ag…
