Abstract (en)
A feeder (1a, 1b), particularly for feeding lids in vacuum crimping machines, comprising a passage channel (2) adapted to guide lids (3) to a crimping station (4) contained in a vacuum chamber (5). The passage channel (2) has a closed profile and passes through a wall (50) of the vacuum chamber (5) so as to connect the environment inside the vacuum chamber (5) to the outside environment. The peculiarity of the invention resides in that it comprises means (7) for pushing the lids (3) which are accommodated slidingly along the passage channel (2) so as to push the lids (3) along the passage channel (2). Advantageously, a hermetic seal is provided between the inner walls of the passage channel (2) and the pusher means (7) so as to prevent the air of the outside environment from filtering through the passage channel (2) into the vacuum chamber (5).
