<p>The method involves actuating needle punching equipments (2, 3) with a phase difference between them such that progressing back and forth motions (91a, 91b) of moving parts are in the opposite direction. The back and forth motions are generated in each needle punching equipment by an angular oscillation of the moving parts around an axis parallel to the width of laps, where the moving parts carry needles (47). An independent claim is also included for a needling installation including needle punching equipments.</p> |
