Apparatus for needling non-woven material

摘要

An apparatus for needling a non-woven material (1) has at least one needleboard (15) which is drivable in a reciprocating manner in the needle-penetration direction and 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). 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). The brush belt (5) and the needleboard (11) are 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. This arrangement is intended to reduce uneven wear on the brush belt 5 caused by the needling operation. Transverse motion is effected by oscillation of the belt by actuation of the rollers 678 or guide table 3 or by oscillation of the needleboard whilst the belt is held stationary.
