Method and device for the embodiment of a depression in the chambers formed between an extractor a flat plate and of the hollow objects thermoformed

摘要

The invention relates to a device for the production of a depression in the chambers formed between an extractor to flat plate and of the hollow objects thermoformed. / p & & p & this extractor comprises a flat plate 10 to which the objects are attached by depression. In order to regulate this pressure to a value sufficient to suspend the weight of the objects, but insufficient to ensure that these do not collapse, air is sucked by means of a fan 6, the negative pressure is adjusted by an air inlet 18, but it allows air to enter into the chambers 17 formed between the objects 13 and the plate by the open channels 19.
