Optimized Preform Feed

A device for transporting plastic preforms to a stretch blow molding machine comprising a feeder device, which transports the plastic preforms, which each comprise a mouth and a body section, to a separating device, which is arranged in transport direction upstream of the stretch blow molding machine, wherein the feeder device comprises an actuable blocking device, which in a first position deblocks the path of transport for the plastic preforms and in a second position blocks the path of transport for the plastic preforms, characterized in that the blocking device is inserted between two consecutive preforms in the area of the preform body sections.

A method for transporting plastic preforms to a stretch blow molding machine wherein the plastic preforms are transported by a feeder device along a transport path to a separating device, said method further involving a blocking device that is switched from a first position for deblocking the transport path to a second position for blocking the transport path, characterized in that a signal for actuating the blocking device is conveyed from a central signal processing unit directly to a valve via a bus system or via a connection means connected to a separate output card.
