Apparatus for needling a non-woven material
View Patent ↗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.
1. An apparatus for needling a non-woven material with at least one needleboard which is drivable in a reciprocating manner in the needle-penetration direction and with a stitch base which is opposite of the needleboard and is made of a continuously revolving brush belt forming a conveyor for the non-woven material, characterized in 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.
2. An apparatus as claimed in claim 1 , characterized in that the traversing drive ( 20 ) comprises at least one axially displaceable deflection roller ( 6 ) for the brush belt ( 5 ) with guide disks ( 22 ) resting on the longitudinal edges of the brush belt ( 5 ).
3. An apparatus as claimed in claim 1 , characterized in that the traversing drive ( 20 ) comprises a guide table ( 3 ) for the conveying strand ( 4 ) of the brush belt ( 5 ) forming the stitch base, which guide table is displaceable transversally to the revolving direction ( 11 ) of the brush belt ( 5 ).
4. An apparatus as claimed in claim 1 , characterized in that the traversing drive ( 20 ) consists of a carriage ( 27 ) which receives the needleboard ( 15 ) and its drive ( 28 ) and can be moved transversally to the revolving direction ( 11 ) of the brush belt ( 5 ).
