Abstract
A drive apparatus for the needle bar of a needle machine includes a first drive mechanism connected with the needle bar and which applies a first movement component extending perpendicular to the needle bar, a second drive mechanism connected with the needle bar which applies second movement component parallel to the needle bar, and an additional mechanism for varying the movement stroke of the parallel component. Two eccentric shafts are assigned to the second drive mechanism, these eccentric shafts being driven at the same speed and the eccentric sections of which having a connecting rod supported thereon converting the rotating movement of the associated eccentric section into a linear oscillating movement. The two linear oscillation movements are supplied to a coupling bridge at two first and second hinge points spaced apart from one another. The coupling bridge is coupled with the needle bar or a carrier thereof at a third hinge point arranged between the first and second hinge points. The additional mechanism for varying the movement stroke of the horizontal component varies the rotary angle position of the two eccentric shafts with respect to one another.
