Patent ID: 8057728

Claim:
A device for extracting plastic preforms provided with a first portion having a predetermined transversal dimension and a second adjacent portion having a transversal dimension greater than the first portion, the device comprising a supporting structure, gripping means suitable to extract the preforms from conditioning cavities, a plate fixed to the supporting structure and incorporating gripping means, which comprise a plurality of straight slits parallel to a predefined direction, wherein each slit is provided with first sections of a first predetermined width and second sections forming constrictions of a second predetermined width, wherein the second predetermined width is smaller than the transversal dimension of the second portion of the preform and greater than the dimensions of the first portion of the preform, whereby the first width is such to allow the second portion of the preforms to fit into the slit, and the second width is such not to allow the second portion of the preforms to fit into the slit, wherein there are provided control and operating means to make the plate move in said direction by a predefined length, whereby the preforms are hooked by the plate when portions of the plate defining the second width register against the second portions of the preforms so as to extract the preforms from the conditioning cavities by reciprocally moving away the plate from the conditioning cavities.
