摘要

The tool assembly (11) has a tool holder (12), a tool (13) and a locking device for detachable locking of the tool with the tool holder, where the tool holder has a compressed air channel. The locking device is configured such that it is unlocked in a predetermined pressure in the compressed air channel. A vent hole (27) stands in fluid connection with the compressed air channel and is arranged such that it is closed in a contact between the tool and a counter tool (14). An independent claim is included for a sealing station with an upper tool.
