The belt (32) is made of flexible material and engages at least two belt pulleys (33, 34), each cassette (21) being housed in a corresponding cassette holder member (37), so that the row of tools (14) is at right angles to the closed trajectory. The cassette holder members (37) are guided by two fixed guides (48). At a tool (14) change station (58), the fixed plate (20) is fitted with a notch (55). Two locking arrangements (59) are able to operate two jaws (61) to lock the sticks (21) in the tool (14) change position. The tool (14) change that is carried out by pincers (62) movable vertically and transversely.
