Installation for transporting container preforms, each preform having a cylindrical body and an open neck, this installation comprising: - a fixed frame; - a transport chain that is moved along a path and comprises a plurality of links that are articulated with respect to one another, each link bearing at least one sheath that is secured thereto, and a spinner provided: ∘ with a spindle mounted so as to slide and pivot with respect to the sheath, ∘ with a pinion that rotates as one with the spindle and meshes with the rack over an active section of the path, ∘ with a spinner tip removably fastened to the spindle by way of a bayonet mount; this installation being characterized in that it comprises at least: - a rack in the form of a chain or a belt and at least locally conforming to said path that comprises a local inactive section PI in which the pinions are decoupled from the rack and an active section PA in which the pinion and the rack are meshed, driving the spinner tip in rotation about the axis A of the spindle; and - a manipulator provided with a tool for removing the spinner tip, said manipulator being automated and situated in the vicinity of the inactive section PI of said path, a device for angular indexing of the spinners, which includes a cam, being arranged in line with said inactive section PI of the path in which the pinions are decoupled from the rack and each spinner being provided with a cam follower that is secured to the spindle and cooperates with the cam in the inactive section PI of the path so as to place the spindle there in a predetermined fixed angular position. - a fixed frame;
