Abstract: A conveyor belt system for intermittently controllably transporting and arresting workpieces. The belt band of a conveyor belt runs between two upward facing shanks of an H-profile track. The conveyor belt is either actively or passively lowered in the area of the appropriate work station so that a workpiece carrier comes to rest on the U-shaped ends of a base support with positional exactness. During working on the workpiece, the belt band runs through underneath the workpiece carrier. The forces resulting from working on the piece are taken up by the two U-shaped ends of the base support. For the further transport of the workpiece carrier the belt band of the conveyor belt is again raised to contact the work piece carrier.
