Abstract: An apparatus (1) for the production of tear-off lids (27), in which a tear-off film (24) is sealed or glued onto the upper side thereof on a sealing surface (18) arranged around a removal opening (17). The apparatus includes a conveying device (13) for lid blanks (9), lid rings (8), and tear-off lids (27), as well as processing stations (14, 19, 21, 25, 26, 29) which are provided in succession in the conveying direction for processing the lid blanks (9), lid rings (8), and tear-off lids (27) and form a processing zone of the apparatus (1) extending in the conveying direction. At least some of the processing stations (14, 19, 21, 25, 26, 29) have lifting tables (5) for receiving lower machining tools which, in the intended operation of the apparatus (1), execute an intermittent upward and downward movement along lifting table guides (6) and, in doing so, work with the lower machining tools from below against associated upper machining tools which are supported on stationary yokes (4). According to the disclosure, the lifting table guides (6) are arranged in an area adjacent to the processing zone of the apparatus, as seen in the conveying direction, on exactly one of the two sides of the processing zone. This leaves the area on the other side of the processing zone largely unobstructed and provides excellent accessibility to the processing zone for inspection purposes and maintenance work.
