Abstract: A method of manufacturing a brake cylinder. The brake cylinder is made form an extruded profile by severing a required length of profile and closing an end thereof with a cap (19). The profile consists of a cylinder jacket (11) with connection ribs (13, 14, 15) projecting therefrom a flange member (22) is fastened to the cylinder jacket (11). The bores (26) for the filling ports and the bores (27) for the pressure connections are bored into the connection ribs (13, 14, 15) radially to the cylinder jacket (11). The bores (26, 27) are also provided with female threads (29) so that respective components may be fastened to the ports and/or outlets. Producing the cylinder by extrusion provides a cylinder jacket of a surface quality high enough to make finishing superfluous.

Abstract: A conveyer (10) is provided for the transport of workpiece carriers (12) to be received by a positioning and holding member (15) for processing of the workpieces arranged on the carriers. A stopper member (30) is arranged behind the positioning and holding member (15) as seen in transport direction. A leading workpiece carrier (I) is stopped by the stopper member (30) in such a manner that a following workpiece carrier (II) is brought to a standstill exactly in the receiving position of the positioning and holding member (15). This allows exact positioning and separation of the workpiece carriers without the need of highly precise control of a separating member. A leading workpiece carrier (I) will remain in its position at the stopper (34) until having stopped a following workpiece carrier (II) in the positioning and holding member (15).
