<p>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.</p> |
