ABSTRACT:
The drive and guide device for a needle bar of a needle loom having a machine stand includes a first crankshaft rotatably supported in the machine stand; a needle bar supported in the machine stand; a first connecting rod supported on a first cam of the first crankshaft and connected to the needle bar; and a guide device for guiding the needle bar along a path extending perpendicular to the needle-punching support surface. The first connecting rod and/or the guide device comprises a leaf spring, which is rigidly connected to the needle bar to transmit a drive or guide force. As a result, lubrication points on elements of the needle loom which move from place to place are eliminated.
