Below a series of processing units as bending and assembling tools a guide rail (12) for a plurality of carriers (20) for work pieces (18) is arranged. The guide rail (12) has a longitudinal bottom slot through which equally spaced dogs (36) of a conveying rail (34) can engage with the carriers (20). The conveying rail (34) is repeatedly moved along a rectangle path including a working stroke with the dogs (36) in working engagement with the carriers (20) and including a return stroke by-passing that carriers (20). Clamping devices (62) clamp the carriers (20) in their working positions at the guide rail (12) during the rectangle path of the conveying rail (34) excluding the working stroke. Work pieces (18) of different shape and size can be conveyed through a processing and assembling machine without requiring modifications of the conveying system.
