ABSTRACT:
An apparatus is described for needling a non-woven material (1) with at least one needleboard (15) which is drivable in a reciprocating manner in the needle-penetration direction and with a stitch base which is opposite of the needleboard (15) and is made of a continuously revolving brush belt (5) forming a conveyor for the non-woven material (1). In order to provide advantageous constructional conditions it is proposed that the needleboard (15) comprises rows of needles which have an even distance of the rows and extend in at least in one section in the revolving direction (11) of the brush belt (5), and that the brush belt (5) and the needleboard (11) can be moved back and forth in a reciprocating manner by means of a traversing drive (20) during the conveyance of the non-woven material transversally to the revolving direction (11) of the brush belt (5) to an extent corresponding to the distance of the needle rows relative to each other or an integral multiple thereof.
