    Abstract: A mixing ring(4) moves between a front ring(2) and an end ring(3), each fixed to the shaft and having channels(2k,3k) either helical, parallel to or at an angle to the shaft axis. The multi-diameter front and end rings have sections with smaller external diameter facing the mixing ring. Both ends of the mixing ring have internal diameters large enough to accommodate the smaller diameter sections of both front and end rings. When the inner ring is in either end position it partly overlaps both front and end ring. At least one, preferably two, axially parallel channels(4k) run along the inside of the mixing ring(4) and are offset from each other. The shaft has a smooth surface in the section between front(2) and end(3) rings and may have one or more circumferential channels. Screw components are connected to the mixer at both ends. Independent claims are included for: a) a use of the mixer in a screw processing machine, particularly in conjunction the screw tip; b) a machine with plastic processing screw incorporating the claimed mixer.

    Abstract: Un dispositivo que comprende una flecha (1), un anillo (2) frontal, que esta conectado no positiva y positivamente a esta flecha, un anillo (3) de extremo, que esta conectado no positiva y positivamente a la flecha a una distancia A desde el anillo frontal, y un anillo (4) mezclador suelto, que es libremente giratorio y esta colocado entre el anillo frontal y el anillo de extremo, en donde el anillo frontal y el anillo de extremo en cada caso tienen cuando menos un canal (2k) o (3k), respectivamente, que corre axialmente paralelo, a un angulo con relacion al eje de la flecha o helicoidalmente, y tiene en cada caso cuando menos dos regiones (2b1 y 2b2) o (3b1 y 3b2) de diametros exteriores diferentes, de las cuales la region con el diametro exterior menos (2b2) o (3b2) esta respectivamente colocada en el lado orientado al anillo mezclador, y el anillo mezclador tiene una primera region (4b1) en la que su diametro interior es suficientemente grande para poder traslaparse con la region de diametro menor del anillo (2b2) frontal, tiene una region (4b2) adyacente en la que el anillo mezclador tiene en su lado interno cuando menos un canal (4k) que corre axialmente paralelo, a un angulo con relacion al eje de la flecha o helicoidalmente al mismo, y tambien una tercera region (4b3) adyacente, en la que el diametro interior es suficientemente grande para que el mismo sea capaz de traslaparse con la region de diametro menor del anillo de extremo (3b2) y el anillo mezclador es tan largo que, en las posiciones de extremo respectivas, el otro de los dos anillos (2) o (3) respectivamente esta parcialmente traslapado por el anillo mezclador.
