    Abstract: An apparatus is described for needling a non-woven material with a support (1) for at least one needleboard (3) with at least two eccentric drives (7, 8) which are drivably connected with the support (1) via connecting rods (9, 10) and with a device for adjusting the mutual angular position of the two eccentric drives (7, 8). In order to provide advantageous constructional conditions it is proposed that the device for adjusting the mutual angular position of the two eccentric drives (7, 8) consists of a superposition gear (17) in a gear train (11) for the drive connection of the two eccentric drives (7, 8).
