Abstract (en)

The method involves executing an elliptic type combined movement in a pre-needling apparatus (3), where the combined movement includes back-and-forth movement and a forward movement of pre-needling needles (47). The forward movement of the needles is utilized for providing a movement to a stack of the apparatus (3) for allowing the introduction of the stack in a consolidation apparatus (2). The stack is directly passed from the apparatus (3) to the apparatus (2), where the apparatuses (2, 3) are combined in a common case (11) for forming a single machine. An independent claim is also included for an installation for working a stack in a pre-needling apparatus.
