ABSTRACT:
There is described an apparatus for needling a web, comprising at least one needle board (2) reciprocatingly movable in stitching direction of the needles via an eccentric drive (5), which needle board is reciprocatingly movable in direction of web movement (16) by means of an additional eccentric drive (15), which consists of two parallel eccentric shafts (17) which are movable in opposite directions and are provided with connecting rods (19). To create advantageous constructional conditions it is proposed that in a manner known per se the needle board (2) is articulated at the eccentric drive (5) for driving the needle board in stitching direction (4) of the needles via push rods (3) which are each movably mounted in a guiding sleeve (10), that the guiding sleeves (10) are pivotally mounted about an axis (12) extending parallel to the eccentric shafts (7, 17) and via a rigid guiding arm (21) are articulated at a coupler (20) connecting the connecting rods (19) of the two eccentric shafts (17) of the additional eccentric drive (15), and that the additional eccentric drive (15) has a means for adjusting the mutual phase position of the two eccentric shafts (17).
