ENDS DOWN DETECTOR APPARATUS

An ends down detector apparatus for detecting the absence of any ends in a series of yarns on a textile machine, such as a spinning frame, and wherein the apparatus includes means for generating electrical pulse signals of varying magnitudes, the intact running ends of yarns cooperating with the generating means to effect electrical pulse signals of a predetermined magnitude denoting the presence of ends of yarns and wherein means are positioned in advance of the series of yarns to effect electrical pulse signals of a higher magnitude than effected by the intact ends of yarns for re-setting the electrical circuit and thereby controlling proper cyclic operation thereof as the ends down detector apparatus moves along the series of yarns.
