<p>A device (10) for receiving bars (11) incoming along two parallel guides (12) in a siderurgical facility, in order to lay said bars onto a cooling bed (38), comprises at least one first element (15) having, at its bottom portion, two channels (16) each of which displays a downwards orientated opening, with said channels being lined up with said parallel guides (12), in order to constitute a substantial extension thereof. For each channel, a shutter means (23, 24) is provided in order to act as a closure means for each of said openings of the channels, and said shutter means are supported by respective arms (17, 18) swinging arounds respective pivot means (19, 20). Each of said arms (17, 18) is linked, through a respective tie-rod (27, 28), to an idle crank (29, 30) installed on a cam (31, 32) rotatably actuated by a ratiomotor (35) in order to reciprocate the shutter means (23, 24) between a closed-channel position and an open-channel position. <IMAGE></p> |
