Abstract
The needling machine includes a support and a stripper defining a path for a lap. A needle board supported by sliding rods has a reciprocating motion between the represented maximum penetration position and the withdrawal position by means of two rod-eccentric devices, each having a rod hinged to the sliding rod. Each pair of rods is hinged to a crankshaft supported by bearings and carrying an equilibration device. The bearings are supported in a crankcase by partitions in a position situated axially between the eccentrics and the equilibration device. The crankshaft extends from the crankcase through simple sealing liners. An advantage of the present needling machine is that the crankcase is stiffened and crankshaft deformations are reduced to increase the striking rate.
