Abstract
Aparato para fabricar tornillos del tipo auto-taladrador que tienen porciones de extremidad de penetración puntiagudas y unas ranuras dispuestas en oposición e inclinadas que se cortan con dichas porciones de extremidad, caracterizado porque incluye un dispositivo para cargar los primordios de tornillo en un trayecto circular predeterminado, un dispositivo para transportar los primordios sucesivos provistos de vástagos descubiertos a lo largo de un trayecto circular predeterminado, incluyendo el dispositivo de transporte unos receptáculos en la periferia de dicho trayecto para recibir y mantener en él los sucesivos primordios, cuatro puestos de trabajo separados circunferencialmente alrededor del dispositivo de transporte y en una posición adyacente a éste, incluyendo cada uno de dichos cuatro puestos de trabajo unos medios de soporte móviles para el montaje de las sierras circulares giratorios de modo que corten selectivamente dicho trayecto de desplazamiento para formar unas ranuras longitudinales en los vástagos de los primordios, incluyendo por lo menos un puesto de trabajo suplementario adyacente al dispositivo de transporte, unos medios para dar una forma puntiaguda a la extremidad de cada primordio, incluyendo además el dispositivo de transporte unos medios para sujetar las cabezas de los primordios y para hacer girar selectivamente cada primordio alrededor de su eje durante el desplazamiento entre los puestos de trabajo de modo que una primera sección periférica predeterminada de cada primordio esté sometida a la acción de dos de dichos cuatro puestos de trabajo y que una segunda sección periférica predeterminada, dispuesta en una posición opuesta respecto a dicha primera sección periférica predeterminada, esté sometida a la acción de los otros dos puestos de trabajo.
