Abstract
A tool unit 20 and a press 21, particularly an embossing press. The tool unit 20 is simply and quickly arranged in or removed from a holder 23 of the press 21 in order to carry out a quick tool change with short downtime of press 21. For this purpose the tool unit 20 comprises a first tool 45 and a second tool 46 that are arranged along a tool axis A on a tool carrier 31. By means of a tool guide device 47, the second tool 46 is movably supported in a guided manner relative to the tool carrier 31 and the first tool 45, independent from guide devices of press 21. Therefore, the tool unit 20 can be prepared and set up during the ongoing operation of press 21. If desired or necessary, the prepared tool unit 20 is exchanged against the presently used tool unit 20.
