ABSTRACT:
A perforated table is pivoted on a vertical axis to a machine frame on one side thereof. An upper set of juxtaposed, closely spaced needling units is arranged over the table in a transverse row. A perforated stripper is disposed between the upper set of needling units and the table. A lower set of juxtaposed, closely spaced needling units is secured to the table and arranged on the underside thereof in a transverse row. Each row of needling units has the same length, which defines the working width of the machine.Drive means for operating the needling units of the upper and lower sets in unison are provided and comprise flexible couplings between adjacent needling units in each set. Each needling unit is provided on the underside with needles and operable by the drive means to move the needles up and down. The needles of the upper set of needling units are operable to penetrate through the stripper and from the outside through an endless fibrous web which lies on the table and extends across the row of needling units of the upper set. The needles of the lower set of needling units are operable to penetrate from the inside through the fibrous web when the same extends around one end of the table and on the underside thereof and across the row of the needling units of the lower set toward the opposite end of the table.
