Abstract

The invention relates to devices and to methods for transporting preforms in the region of a blow-molding machine, in particular a sorting device (10) for transporting preforms (20) composed of a thermoplastic material in the region of a blow-molding machine for the blow-molding of containers, comprising a transportation wheel (12), which has a plurality of accommodating recesses (18) for accommodating and conveying the preforms (20), which accommodating recesses are arranged on the circumference of the transportation wheel in such a way that the accommodating recesses are distributed in the circumferential direction, a guide collar (16), which extends circumferentially around the transportation wheel (12) in some regions in such a way that the guide collar is radially spaced apart from the transportation wheel, wherein the preforms (20) are transported in suspension between the transportation wheel (12) and the guide collar (16) in the region of the sorting device (10), and a selection unit for selectively removing a respective individual preform (20) transported in one of the accommodating recesses (18) of the transportation wheel (12), wherein the selection unit comprises a pivo…
