  • Facility for needling of fleece
    Patent number: 6481071
    Abstract: The description refers to a facility for needling of fleece with a needle bar (6) taking up at least one needle board (1), which is driven to and fro via axially displaceable pushing rods (7, 8) by means of an eccentric drive (11). To facilitate a longer needle board in fleece feed direction, we suggest to fix the needle bar (1) at two rows of pushing rods (7, 8), arranged in tandem at some distance from each other in fleece feed direction and connected via a crosshead (9), and to make the eccentric drive (11) act upon the crosshead (9).
