<p>An apparatus is described for needling a non-woven material with a support (1) receiving at least one needleboard (3), which support is drivable in a reciprocating fashion both in the needle-penetration direction (5) as well as the direction of passage (6) of the non-woven material and on which are coupled the connecting rods (9, 10) of two oppositely drivable eccentric drives (7, 8) for the drive in the needle-penetration direction (5) and on which acts at least one additional eccentric drive (7, 8), and with a device for setting the movement component of the support in the direction of passage (6) of the non-woven material. In order to provide advantageous constructional conditions it is proposed that the connecting rods (9, 10) of the two oppositely drivable eccentric drives (7, 8) extend inclined in an opposite direction with respect to the needle-penetration direction (5), that the additional eccentric drive (7 or 8) revolves synchronously with one of the two other eccentric drives (7, 8), that the connecting rod (9 or 10) of the additional eccentric drive (7 or 8) which is also articulated on the support (1) forms a parallelogram of links with the connecting rod (9 or 10) of the synchronously revolving eccentric drive (7 or 8) for the purpose of guiding the support (1) and that the oppositely drivable eccentric drives (7, 8) are drivable through separate motors (18) which are adjustable with respect to their mutual rotational angle position through a control device (19).</p> |
