Abstract: A device for converting rotational movement into axial movement includes planetary rollers driven by a drive shaft projecting from a drive device and maintained peripherally at a same distance, in addition to a push body axially displaced by the planetary rollers. These planetary rollers are peripherally fixed on a support which is driven around the axis thereof, the rollers being rotationally mounted and provided with peripheral grooves or threaded grooves; the support is connected in a fixed manner to the drive shaft rotating around its axis; the planetary rollers engage in at least one thread-like groove of the push body that is displaced along the axis of the support by means of their peripheral grooves or threaded grooves.

Abstract: The invention relates to a device for coiling a thread or wire-type object (1) onto a winding jig (10) by means of a flyer (7) circling the winding jig (10). The object (1) is guided to the flyer (7) by a tube (2) and the flyer (7) is positioned on the tube (2) in rotating manner. Said winding jig (10) is coupled to a carrier sleeve (18) which is arranged approximately in the direction of the longitudinal axis (A) of the tube (2), at a distance (A) from the same, in order to pass the object (1). Said carrier sleeve (18) is associated with the fixed tube (2) in a fixed manner.
