This eliminates any need for a further transfer of the sewing-material part 92 to a clamping rail for guiding it along the sewing machine 2. The plate edge parts (54, 55) serve, in the clamped position of the sewing-material part (92), for holding the sewing-material part (92) during the sewing process.

Abstract: The invention relates to a rail for accommodating and guiding a conveyor for transporting goods hanging on hangers. The conveyor may be a roller chain which travels and is guided in a chain channel in the rail. The tips of the hanger hooks rest on the roller chain. The chain channel is recessed with respect to the top side of the rail, which faces the hanger hook, and a conical groove extends upward from the roller chain and opens upward toward the outside of the rail. These features make it possible to transport the hanger hooks on their tips. The bevel which is formed by the conical groove, as well as the shape of the rail and the relative positions of the chain channel and the side edge of the rail, ensure that the hanger hook always slides in a well-defined position and orientation on the roller chain regardless of how it has been placed on the conveyor.
