Continuous twisting or stranding machine A twisting, doubling and/or stranding machine in which one of the yarns (1) is supplied from elemental spools (B) supported on a creel (3) mounted at the upper part of the machine, it being possible for said creel to be moved between a lowered loading position and a raised working position and vice versa. According to the invention, control of the movements of the spool-holder creel (3) is provided by a ram (14) mounted on the articulated pantograph-form assembly and the end of the rod of which can pivot about a fixed point (15) of the plate (6) fixed to the structure of the machine, and can do so in such a way as to adopt two positions-one in which the rod of the ram is in the retracted position inside the body, positioning the creel (3) in a lowered loading position-movement into the raised position being obtained by action of a fluid, liquid or air under pressure, acting on the front face of the piston and tending thus to push the body of the ram (14) along the rod to bring it into the raised working position.
