Abstract
A needle loom including a support and a stripper defining a path for a fiber lap. A needle board supported by sliding shanks moves back and forth between a maximum penetration position and a retracted position, by means of a connecting rod/crank assembly including a connecting rod hingedly connected to the sliding shank. A slide bearing remote from the needle board has a greater diameter than the other slide bearing, and engages a tubular portion of the shank. The hinge connection between the connecting rod and the sliding stank is located within the axial section covered by the slide bearing and the interval therebetween. For this purpose, the hinge is arranged in the tubular portion. Bearing wear, extraneous stress and vibration may thus be reduced.
