An apparatus for treating molded objects all having a predetermined object length in a treatment station has first and second transversely spaced conveyor strands extending longitudinally in a travel direction into the treatment station for displacing the object in the travel direction into the treatment station. Respective first and second holding bolts are supported by the respective strands and secured in respective ends of the objects with the objects extending transversely between the strands. A plurality of longitudinally spaced and transversely extending support elements are fixed to and longitudinally displaceable with the first strand. The first bolts are supported on the elements that each have a transverse length equal to at least 30% of the length of the first holding bolt between the respective end of the respective molded object and the first conveyor strand, or 10% of the length of the molded objects, or 30 mm.
