  • Patent number: 3995417
    Abstract: An electrical process and device are described wherein interruptions in the passage of yarn from a series of supply bobbins, used in succession, to a wind-up bobbin are detected by a yarn breakage surveying device that transmits an impulse for each interruption. Some of these interruptions are due to supply bobbin changing and others to yarn breakages. Only the interruptions due to breakages are transmitted to a counter by way of a gate that receives the said impulses as well as periodic signals from a timing device. The timing device is actuated for spaced periods initiated by signals from a differentiating circuit for each change from "no yarn" to "yarn present" indicated by the surveying device, the latter being connected to the differentiating circuit as well as directly to the timing circuit.
