ABSTRACT:
In a method of conditioning preforms to be molded into containers which includes feeding them in groups to a temperature-conditioning zone where they are reduced to orientation temperature for immediate molding into containers, improvements are provided which involve diverting other groups away from the temperature-conditioning zone to an adjacent cooling zone wherein they are reduced to a temperature whereat sticking together cannot occur, prior to collecting them for later molding.
