A device and process for extracting plastic preforms (5) from holders. Said device comprises a plate (23), which features straight slits (26) positioned parallel to each other, that is attached to a supporting table (20, 21). Each slit (26) comprises wider sections and constrictions (29, 30), which have a width (L2) smaller than the diameter of the ring (9) of the preform, so that the ring (9) can be fitted into the slit (26) through the wider section. The plate (23) is moved in the direction «D» by a specific length until the constrictions are positioned under the ring, and, thus, the preforms are removed by moving the plate away from the holders.
La présente invention concerne un dispositif et un procédé pour extraire des préformes en plastique (5) de supports. Ce dispositif comprend une plaque (23) qui présente des fentes droites (26) placées parallèles les unes aux autres et qui est reliée à une plaque de support (20, 21). Chaque fente (26) comprend des sections plus larges et des étranglements (29, 30) qui présentent une largeur (L2) inférieure au diamètre de la bague (9) de la préforme, de façon que la bague (9) puisse être intégrée dans la fente (26) à travers la section plus large. La plaque (23) est déplacée d'une longueur spécifique dans la direction "D", jusqu'à ce que les étranglements soient placés sous la bague et, ainsi, les préformes sont retirées en éloignant la plaque des supports.
