Abstract
The description relates to a facility for needling of fleece with at least one needle board driven to and fro in stitching direction, which can be additionally driven in pendulum fashion in fleece feed direction ( ) by means of an eccentric drive, which is provided with a connecting rod ( ) articulated to a rocker arm ( ) and a connecting pitman ( ) to the needle board effective on this connecting rod assembly. To be able to easily adjust the rocking amplitude of the needle board in fleece feed direction ( ) it is suggested that the swivel bearing ( ) of the rocker arm ( ) is seated on a rotatable crank arm ( ) and that, for adjustment of the rocking amplitude of the connecting pitman ( ), the neutral rocking position of the rocker arm ( ) is adjustable via the crank arm ( ) between an end position essentially running in the direction of the connecting pitman ( ) and an end position running transverse thereto.
