The device for guiding round parts rotating about their axes comprises three segments (2, 3, 4) which form a closed passage (26) for the guided bar (1). The lower segments (2, 3) form a V-shaped support for the bar (1). The lower segment (2) may pivot about the shaft (8). The upper segment (4) may pivot about the shaft (9) and its lower edge (31) sweeps, during its opening or closing run, the guiding surface (10) of the fixed segment (3) while maintaining a slot (13). The segments (2, 3, 4) are dimensioned and arranged so that they always form, during the opening and closing motions and except during the insertion of a new part, a variable cross-section closed passage (26). The segments (2, 3, 4) guide the parts throughout their length. The motions of the segments are synchronized by means of the rod (6). |
