ABSTRACT:
Apparatus for handling and cooling preforms, comprising a collection element provided with a plurality of receptacles arranged according to a definite geometrical distribution pattern and adapted to accommodate a corresponding plurality of preforms, as well as a cooling element. The collection element is displaceable from a preform loading position to several distinct positions, arranged above the cooling element, which is provided with a plurality of cups collected into a plurality of distinct, but similar geometrical distribution patterns that are translated with respect to each other in such a manner as to prevent them from interfering with each other. The collection element can be selectively positioned in a number of such positions as to ensure that, in each one of said positions, the geometrical distribution pattern of the receptacles comes to be placed exactly above a specific geometrical distribution pattern of the cups, so that the preforms are capable of falling from the receptacles exactly into respective cups.
