Abstract:
An apparatus is described for needling a non-woven (2) with at least one support (6) for a needleboard (4) held in a frame (12) and with two parallel eccentric drives (7, 8) which are disposed between the frame (12) and the needleboard support (6) and are made of two parallel eccentric shafts (9 and 10) each for the needleboard drive in the needling direction on the one hand and in the direction of passage of the non-woven on the other hand. In order to provide advantageous constructional conditions it is proposed that an intermediate support (13) is provided between the needleboard support (6) and the frame (12) and that the intermediate support (13) is guided with respect to the frame (12) and the needleboard support (6) with respect to the intermediate support (13) in circular paths by way of the two eccentric drives (7, 8) which are disposed on the one hand between the frame (12) and the intermediate support (13) and on the other hand between the intermediate support (13) and the needleboard support (6).
