A rocking station includes a frame in which there is a powered rocking board onto which are fed objects to be rocked. The board is supported on the floor supports arranged near its two opposite ends with the supports defining two parallel rotation axes of the board with each one near one of the opposite ends and transversal to the board. On each side of the board there is a chain defining two main lifting branches with each main branch being arranged between one part of the frame above the board and couplings to the board being arranged near one of the opposite ends of the board. A motor causes the chains to run on command in one or the other direction to alternately place one main branch or the other under tension and lift the corresponding board end by rotating the board around the rotation axis near the opposite end.
