Abstract
Abstract A drive for a needling machine including a crank shaft for reciprocating a needle board and linkages for connecting the crank shaft to said needle board. One of the linkages is fixed to the needle board and guided for movement in a rectilinear path, while the other of said linkages is connected to the crank shaft for movement therewith at one of its ends and the other of its ends is pivotally connected to the linkage fixed to said needle board at a point intermediate spaced bearing means which guides it in a rectilinear path.
