dynamometrisk avkenningsanordning for overvakning of rorelsetillstandet in tradformade foremal

摘要

The present invention relates to monitoring devices of the type making use of the principle that frictional contact between two bodies gives rise to electrical charges or voltages on the bodies. The monitoring device of the invention comprises yarn guiding means, at least one signal electrode and at least one ground electrode. Means are provided for generating yarn travel signals exhibiting improved continuity and a high signal-to-noise ratio.
