The machine is principally constituted by a wheel comprising at its periphery two rows of hammers adapted to overlap one another alternately, each of the hammers of one row being carried by a slide moving transversally on said wheel, means being provided to ensure the alternate pivoting of the hammers, from one row to the other, during the rotation of said wheel in order to provide particularly, by the transversal movement of the slides, the cambering of the thread and the disengagement of said hammers when the thread is cambered, the latter being eventually taken up by a second device composed of two plates arranged facing one another symmetrically with respect to the direction of advance of the thread and each comprising spiral grooves for the reduction of the pitch of the zig zag cambered thread.
