Zusammenfassung:	V²choz polotovar se postupn , v dan m po°ad p°ih²b , tvaruje, kalibruje a rovn , p°i em jednotliv pracovn f ze se prov d j v jednom a tomt lisu (1) po v²m n ch pracovn ch n stroj (6, 13, 14). Lis (1) k uskute ov n tohoto zp sobu je opat°en manipul torem pracovn ch n stroj (6, 13, 14), kter jsou vym niteln uspo° d ny na hydraulick²ch agreg tech (4) a na stole (7) lisu (1).\ Disclosed is a process for manufacture of large bore pipes from steel plates during which the operations such as edge bending, pipe forming, sizing and straightening are carried out in sequence in the same press (1) after interchange of appropriate tooling (6, 13, 14). The press (1) for carrying out the operations is provided with a manipulator of working tools (6, 13, 14) that are exchangeable arranged on hydraulic units (4) and on the press (1) table (7).
