Abstract
An apparatus is described for needling a non-woven ( ) with at least one support ( ) for a needleboard ( ) held in a frame ( ) and with two parallel eccentric drives ( ) which are disposed between the frame ( ) and the needleboard support ( ) and are made of two parallel eccentric shafts ( and ) each for the needleboard drive in the needling direction on the one hand and in the direction of passage of the non-woven on the other hand. In order to provide advantageous constructional conditions it is proposed that an intermediate support ( ) is provided between the needleboard support ( ) and the frame ( ) and that the intermediate support ( ) is guided with respect to the frame ( ) and the needleboard support ( ) with respect to the intermediate support ( ) in circular paths by way of the two eccentric drives ( ) which are disposed on the one hand between the frame ( ) and the intermediate support ( ) and on the other hand between the intermediate support ( ) and the needleboard support ( ).
