Abstract
An apparatus for monitoring the yarn delivered by an open end spinning turbine which has an electric motor for driving the turbine with a predetermined rpm. The apparatus includes a measured value transmitting arrangement responsive to changes in the current consumption of the electric motor for generating a signal when the change in the current consumption exceeds a predetermined threshold value. The measured value transmitting arrangement is responsive to a reduction in the current consumption of the electric motor and generates a yarn breakage indicating signal when the reduction in the current consumption falls below a predetermined value indicative of yarn breakage.
Claims8
In an apparatus for monitoring the yarn delivered by an open end spinning turbine including an electric motor for driving the open end spinning turbine with a predetermined rpm;
- the apparatus including a measured value transmitting means responsive to changes in the current consumption of the electric motor for generating a signal when the change in the current consumption exceeds a predetermined threshhold value;
- the improvement wherein said measured value transmitting means includes sensing means responsive to a reduction in the current consumption of said electric motor and signal generating means operatively connected to said sensing means for generating a yarn breakage indicating signal when the reduction in the current consumption of said electric motor falls below a predetermined value indicative of yarn breakage.
