The tools (36) of the various machining heads (33) are housed on a common drum (57), which is remote from the heads (33) and rotated to select a given row of tools (36). At each head (33), there is provided an intermediate station (62) having a container (63) housing a row of tools (36); and a shuttle (82) provides for sequentially transferring the tools (36) between the drum (57) and the intermediate stations (62). Each container (63) is rotated 90 DEG between a position cooperating with the shuttle (82) and a position cooperating with a device (43) for exchanging the tools (36) between the head (33) and the container (63). The container (63) is also movable with respect to the device (43) to select the location of the tool (36) to be changed. <IMAGE> |
