ABSTRACT:
The present invention pertains to a transfer press which achieves a reduction in the overall length of the press line and, hence, in the total weight, while ensuring high efficiency and safety of preparatory work, such as changing of idle nests, owing to a facility which permits such a preparatory work to be performed externally of the press. To these ends, the transfer press has: an upright (3) disposed between and commonly possessed by adjacent press units (P1, P2); locating means (4A, 2A) for locating adjacent crowns (4, 4) with respect to each other and adjacent beds (2, 2) with respect to each other, respectively; and a tie rod (7) extending through the boundary between the adjacent beds (2, 2) and through the boundary between the adjacent crowns (4, 4), the adjacent crowns (4, 4) and the adjacent beds (2, 2) respectively being tied together through the upright (3).
