Abstract (en)
[origin: WO9621764A1] The needling machine comprises a support (1) and a stripper (2) defining a path for a lap (3). A needle board (7) supported by sliding rods (11) has a reciprocating motion between the represented maximum penetration position and the withdrawal position by means of two rod-excentric devices comprising each a rod (19) hinged to the sliding rod (11). Each pair of rods is hinged to a crankshaft (23) supported by bearings (34) and carrying equilibration means (27). The bearings are supported by wholes (39) in a position situated axially between the excentrics (22) and the equilibration means (27). The crankshaft (23) comes out of the crankcase through simple sealing liners (36). Utilization for rigidifying the crankcase and reducing the deformations permitted to the crankshaft in order to increase the striking rate.
