Abstract
An apparatus for exhausting and collecting gases comprising a slotted exhaust conduit fixed in position and provided on its one face with an elastic, axial lip seal for guiding in sealed relationship a suction nozzle of at least one carriage which can be moved in the axial direction along guide sections. The suction nozzle is connected to a hose, and a vacuum is generated in the slotted exhaust conduit through an exhauster. In order to make such a system suited for use in factory halls in which the space above the assembly system and the operating space must remain clear from obstructions in order to permit cranes or assembly installations, or the like, to be positioned and operated in this clear space, the slotted exhaust conduit is arranged below axially movable assembly frames. The carriage can be moved in synchronism with the assembly frames. The lips of the lip seal are directed upwardly and the hose takes the form of a bellows and can be attached to an opening in the assembly frame from below.
