Abstract
A multistation press has a three-axis transfer provided with transport rails onto which carrier rails are placed. The carrier rails carry grippers for the workpieces. During the tool change, the carrier rails are deposited on corresponding receiving devices of the sliding table. The transport rail is at first moved to deposit a first carrier rail connected therewith on the receiving device. Then the transport rail is separated from the carrier rail and is moved to bring a second carrier rail still connected therewith to the receiving device. The receiving device receives the second carrier rail in the immediate vicinity of the first carrier rail, whereby two carrier rails overlap and are spaced closely side-by-side. The receiving device is then laterally swivelled away. The carrier rails are deposited on the receiving device without the aid of driving devices operating between the transport rail and the carrier rail.
