Abstract: A winding-up attachment for a long, flexible element, in particular a hose, comprises a rotatable drum for winding-up and for unwinding the element. A return device rotates the drum in the winding-up direction or in the unwinding direction, respectively. It comprises an automatic brake for stopping the winding-up process or the unwinding process, respectively, at a predetermined rotary stop position of the drum in which the element has been wound up or unwound, respectively, in full, except for a defined residual length. The brake comprises a winding-up device that rotates together with the drum and winds/unwinds an elongated, flexible braking element, e.g. a cord. The braking element is wound about an outer surface of the drum in several windings. One terminal end of the braking element is connected with a circumferential surface of the drum. The braking element is sized such that when the drum reaches the predetermined stop position, it is stopped by a tension force within the braking element.

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.

Abstract: A system serves for exhausting and collecting gases, in particular motor vehicle exhaust gases in an assembly or factory hall. A stationary slotted exhaust conduit (18) is provided on one face with an elastic, axial lip seal for guiding in sealed relationship a suction nozzle of at least one carriage (16) which can be moved in the axial direction along guide sections (41). The suction nozzle is connected to a hose and a vacuum is generated in the slotted exhaust conduit (18) through an exhauster.
