Abstract
High speed apparatus for the extraction and opening of bags contained in a magazine in which they are arranged in a flattened condition so as to form a pack. The apparatus is composed of a pair of extracting devices comprising elements provided with suction cups and supported oscillating between a position of extraction of the bags from the magazine and one of release of said bags onto a receiving device. The suction elements are actuated in opposite phase so that while one element, after extracting the related bag, is about to transfer it onto the receiving device, the other element is in the return phase. In order to prevent the extracting elements from colliding with one another, it is provided that the path followed by the elements during the extracting and transfer phase be different from the path followed during the return phase. The apparatus also provides an extended time for opening the bags.
