Abstract

A transporting apparatus serves for transporting containers in a container-handling installation, which has a first container-handling arrangement for handling containers, and a second container-handling arrangement, which is arranged downstream of the first handling arrangement and serves for handling the containers once they have been handled by the first container-handling arrangement. The transporting apparatus includes a transporting path, which has its entire length arranged between the first and second container-handling arrangement and along which the containers can be transported from the first container-handling arrangement to the second container-handling arrangement. The apparatus includes at least one transporting element, which is mounted in a movable manner on the transporting path and is intended for retaining and transporting a container. The transporting path and the at least one transporting element are configured such that the at least one transporting element, en route between the first and second container-handling arrangements, compensate for a difference in speeds of transportation of the containers in the first and second container-handling arrangements.
