Abstract:
The invention concerns a forming head for an apparatus for the production of a non-woven fabric by depositing fibers on a conveyor belt, comprising a fiber feeder which opens into a fiber processing chamber and which has a lower deposit opening for the delivery of fibers, wherein arranged in the fiber processing chamber are interengaging needle rollers with longitudinal axes oriented in mutually parallel relationship, which can rotate about their respective longitudinal axis, and the interengaging needle rollers enclose an inner chamber and are arranged with respect to the fiber feeder and the deposit opening in such a way that fibers fed to the forming head in operation enter the inner chamber by passing through between interengaging needle rollers and leave the inner chamber also by passing through between interengaging needle rollers.
