Apparatus and process for transferring at least a portion of a running web from a first section of a web making machine to a second section of the web making machine arranged downstream from the first section, relative to a web run direction, the second section including a portion adapted to receive a full width of the running web and a rope section located outside of the full width receiving portion. The apparatus includes at least two pulleys, in which at least one is a driven pulley, a suction box coupled to a vacuum source, an air-pervious endless conveyor belt tensioned over the at least two pulleys to form a conveying run and a return run, and a device for creating a negative pressure at an inner surface of the conveying run. The at least one driven pulley being adapted to drive the endless conveyor belt over the at least two pulleys while the negative pressure propagates through the conveying run. The endless conveyor belt includes an upstream and a downstream end and the endless conveyor belt is pivotable around a pivot axis located in a region of the upstream end. The endless conveyor belt is pivotable to move the portion of the running web between the rope section and the portion is adapted to receive a full width of the running web. The apparatus also includes a control system for moving the downstream end into an area of the web width when a beginning of the at least a portion of the web has entered the rope section. The process includes rotating the endless conveyor belt by driving the at least one driven pulley, creating a negative pressure at an inner surface of the endless conveyor belt as the endless conveyor belt is guided over the suction box, and guiding the at least a portion of the running web onto the endless conveyor belt. In this way, the at least a portion of the running web is suctioned onto the endless conveyor belt. The process also includes transferring the at least a portion of the running web from the endless conveyor to the rope section located outside of a web width, pivoting the endless conveyor belt around the pivot axis to move the downstream end into an area of the rope section one of at and before the transferring, and pivoting the endless conveyor belt around the pivot axis to move the downstream end into an area of the at least a portion of the running web and inside the web width.
