De este modo es posible ajustar la posición de los rodillos con respecto al brazo basculante al aflojar la pieza portadora de los rodillos, haciendo correr en una o más ranuras dicha pieza hasta nueva coincidencia con el ranurado inferior para variar el posicionado lateral de los rodillos de la manera deseada. La fijación de la pieza ranurada portadora del conjunto de rodillos se efectuará por un sistema rápido, por ejemplo, un dispositivo de excéntrica, de manera que las posibilidades de ajuste quedan ampliamente incrementadas y la operación de ajuste resulta muy simple y rápida.To achieve its objectives, the present invention provides for the realization of a support arm for the pair of rollers wire guidance comprising a wide central opening for the lateral displacement of the roller bearing shaft support, being fixed in position by combining a grooved surface made in a joint part of the arm swingarm and other grooved piece conjugated and arranged in opposition, which is the carrier of a shaft support rod equipped with rollers In this way it is possible to adjust the position of the rollers with respect to the swing arm when loosening the piece roller carrier, running in one or more grooves said piece until new coincidence with the lower grooving for vary the lateral positioning of the rollers as desired. Fixing the grooved carrier part of the roller assembly it will be done by a fast system, for example, a device of eccentric, so that the adjustment possibilities remain widely increased and the adjustment operation is very simple and fast.
La pieza superior portadora del conjunto de rodillos y la pieza inferior asociada al brazo basculante pueden llevar referencias marcadas que facilitan el trabajo de ajuste y la reproducción eventual del
\hbox{mismo}.The upper part carrying the roller assembly and the lower part associated with the tilting arm can have marked references that facilitate the work of adjustment and the eventual reproduction of the
\ hbox {same}.

Las figuras 4, 5, 6 y 7 muestran sendos detalles de la pieza asociada al brazo basculante, según secciones por los planos de corte indicados, una vista en planta y una vista en alzado.Figures 4, 5, 6 and 7 show two details of the piece associated with the swing arm, according to sections by indicated cutting planes, a plan view and a view in raised.
Las figuras 8, 9 y 10 representan sendos detalles de la pieza superior soporte de los rodillos respectivamente según una vista en alzado frontal, sección longitudinal y vista en planta.Figures 8, 9 and 10 represent two details of the upper part support of the rollers respectively according to a front elevation view, longitudinal section and view in plant.
Tal como se aprecia en las figuras, el dispositivo objeto de la presente invención queda acoplado al brazo basculante (1) portador de los rodillos (2) y (3) de guiado de los hilos en sus respectivas gargantas (4) y (5), disponiendo de una pieza (6) que queda acoplada en el extremo de dicho brazo (1), por ejemplo, por ensartado de el extremo de dicho brazo en ranuras de la mencionada pieza y tornillos y tuercas transversales de fijación (7) u otro mecanismo similar, poseyendo dicha pieza (6) un amplio escote (8), figura 3, que es atravesado por el eje (9) portador de los rodillos, poseyendo además una abertura transversal superior (10), en forma de coliso, a lo largo de la cual se puede desplazar el vástago (11) asociado a una pieza (12) portadora del eje (9) de los rodillos.As can be seen in the figures, the device object of the present invention is coupled to the arm swingarm (1) carrier of the rollers (2) and (3) of guiding the threads in their respective throats (4) and (5), having a piece (6) that is coupled at the end of said arm (1), by for example, by skewering the end of said arm in grooves of the mentioned part and screws and cross fixing nuts (7) or another similar mechanism, said piece (6) having a wide neckline (8), figure 3, which is crossed by the axis (9) carrying the rollers, also having an upper transverse opening (10), in the form of a colosseum, along which the rod (11) associated with a shaft bearing part (12) of the rollers
La pieza (12) es solidaria del vástago (11), el cual atraviesa una pieza superior (13) susceptible de desplazarse a lo largo de la ranura (10) para conseguir las posiciones de ajuste deseadas para los rodillos (2) y (3). Para realizar dicho ajuste, las piezas (6) y (13) presentan sendos ranurados de forma conjugada en sus caras opuestas entre sí, que se han representado en las figuras 4 a 8, observándose que la pieza (6) presenta un ranurado (14) en su cara superior sobre el que coincide un ranurado (15) de la cara inferior de la pieza (13). Al variar las ranuras de acoplamiento entre dichas piezas, se cambia la posición transversal de los rodillos con respecto al brazo (1).The piece (12) is integral with the rod (11), the which crosses a top piece (13) capable of moving to along the groove (10) to achieve the adjustment positions desired for the rollers (2) and (3). To make such adjustment, the pieces (6) and (13) have both grooves conjugated on their faces opposite each other, which have been represented in the Figures 4 to 8, observing that the piece (6) has a grooving (14) on its upper face on which a grooved (15) of the underside of the piece (13). By varying the slots of coupling between said parts, the transverse position is changed of the rollers with respect to the arm (1).
La fijación de la pieza (13) en su posición de trabajo se consigue mediante cualquier dispositivo conocido en la técnica, por ejemplo, un dispositivo de excéntrica (15) sobre el que actúa un resorte (16) mantenido inferiormente por medio de un tapón ajustable (17).Fixing the part (13) in its position of work is achieved by any known device in the technique, for example, an eccentric device (15) on which a spring (16) operated inferiorly by means of a plug acts adjustable (17).
Mediante la disposición de elementos explicada se observa que el dispositivo objeto de la presente invención presente unas características de notable simplicidad y eficacia funcional. En efecto, es suficiente aflojar el dispositivo de excéntrica (19) para permitir el desplazamiento de la pieza (13) al lugar deseado, eventualmente con ayuda de las marcas de ajuste (18) de la pieza (13) y eventualmente de la pieza (6), volviendo a apretar a continuación la excéntrica (19) para que la nueva posición de ajuste quede debidamente fijada.Through the arrangement of elements explained, Note that the device object of the present invention is present characteristics of remarkable simplicity and functional efficiency. In effect, it is sufficient to loosen the eccentric device (19) to allow the movement of the piece (13) to the desired place, possibly with the help of the adjustment marks (18) of the piece (13) and eventually the part (6), tightening again to then the eccentric (19) so that the new adjustment position is properly fixed.
Para posibilitar el guiado de la pieza superior (13) en el sentido del eje del brazo (1), la misma posee inferiormente un cuello (20) que ajusta de modo deslizante en el interior de la ranura (10), posibilitando su desplazamiento transversal con respecto al brazo (1), pero imposibilitando el desplazamiento axial del mismo.To enable the guidance of the upper part (13) in the direction of the arm axis (1), it has inferiorly a neck (20) that slides in the inside the groove (10), allowing its displacement transverse with respect to the arm (1), but making it impossible to axial displacement thereof.
Todo cuanto no afecte, altere, cambie o modifique la esencia del dispositivo descrito, será variable a los efectos de la presente invención.Everything that does not affect, alter, change or modify The essence of the described device will be variable for the purposes of The present invention.
